LAN Modules with Low Insertion Loss and High Interference Suppression

Specifically for LAN applications, EPCOS has developed magnetic modules for both electrical isolation and suppression of common-mode and differential-mode interference. These modules are available in single, dual and quad-port versions and are qualified to IPC/JEDEC J-STD-020C and IEEE 802.3. The electrical isolation can withstand a breakdown voltage of 1500V AC.

The insertion loss of the modules is only -1.0dB. Values of -16dB and -40dB are attained for return loss and crosstalk, respectively. In addition to the standard temperature range from 0ºC to +70°C, versions with an extended temperature range from -40ºC to +85°C were developed for industrial applications. Typical applications are 10/100 Base-T, 1000Base-TaswellasPoweroverEthernet(PoE).

Ethernet Protocol is the common basis for data communication in LANs. The physical layer of the Ethernet is standardized in IEEE 802.3. Dependingon the technology, different transmission speeds can be distinguished: 10 Base-T with 10Mbit/s, 100 Base-T with 100Mbit/s and 1000 Base-T with 1 Gbit/s transmission speed. IEEE 802.3af describes transmission of power via the Ethernet port. This technology iscalledPoweroverEthernet (PoE)andis necessary to implement applications like Voice over IP (VoIP)where thephone is powered via the Ethernet connection.

The transceiver chip side (PHY) and the medium side (connecting cable) must be galvanically isolated. EPCOS magnetic modules provide minimum 1500V dielectric isolation combined with excellent insertion and return loss as well as crosstalk and differential to common-mode rejection.

Superior Connectivity

32-Bit Microcontroller with USB OTG, Ethernet with IEEE 1588, Dual CAN and Audio Class I²S

The STM32 Connectivity Line makes networking economical as a result of an embedded Ethernet MAC with a dedicated DMA controller. The IEEE 1588 precision time protocol hardware support providesaccurateclocksynchronizationover thenetwork and retains ample CPU bandwidth to implement an embedded application.

USB 2.0 OTG makes the STM32 Connectivity Line a turnkey solution to add a USB device, host or OTG function to a product. Firmware upgrades in the field, data logging or data storage are now as easy as connecting a standard USB mass storage device to the STM32. Adding a USB keyboard, mouse or any other device is just as easy.

The dual CAN 2.0B makes the STM32 Connectivity Line a turnkey solution to implement a CAN gateway. Also since dual CAN and USB peripherals can be used simultaneously, the STM32 is the perfect fit to connect a computer or USB device to CAN networks.

Superior Audio: Audio Class I²S

The two audio class I²S of the STM32 Connectivity Line, combined with the embedded Ethernet and USB OTG peripherals, address the connectivity and features required of many home audio applications.

The high quality audio is achieved thanks to a new PLL block with the two I2S peripherals, which then generate the accurate master clock for the audio DAC.

The USB 2.0 OTG controller can connect any USB device, including USB mass storage devices and portable audio players. The powerful Cortex-M3 core running at 72MHz is able to handle audio decoding of music files stored on an SD card or USB mass storage device connected to the STM32, as well as the user interface.

The OM7622/BGU7003,598 demonstration board that lets the designer evaluate noise figures, gain, input and output reflection coefficients and reverse isolation.

General Purpose Microwave MMIC LNAs

The BGU7003 general purpose LNA uses NXP Semiconductors’ latest 110GHz Ft SiGeC microwave possessing technology QUBiC4X. The LNA is useful from 40MHz to 6.0GHz in home automation applications where high performance wireless links are a key requirement. Its small footprint, low cost and high performance make it an attractive alter-native to devices that use GaAs technology.

The BGU7003 is easily configurable to produce the balance of gain, current consumption and IIP3 required by RF and microwave receiver front ends.ItssmallsizereducesthePCBfootprintand reduces overall system cost. Its low noise and stable gain improves receiver sensitivity. Its high IIP3 reduces the requirements on front end filtering and susceptibility to jamming signals. An internal biasing circuit keeps current constant over a wide temperature range. Low active and shutdown current consumption allows for longer battery lifetime.

ZigBee operates in the industrial, scientific and medical (ISM) radio bands; 868MHz in Europe,915MHz in countries such as USA and Australia and 2.4GHz in most jurisdictions worldwide. Toextend the functionality of these devices into other application spaces, it is possible to trade low power consumption for range by adding an external Power Amplifier (PA) and/or a LowNoiseAmplifier(LNA).Thetablesprovidegeneral guidance on selecting these external components. A major consideration is the selection of a PA and/or LNA, are the limits imposed by regional standards. In the US it is limited to 1W, in Europe 100mW and Japan 10mW. Adding an external PA and low noise amplifiers can increase the transceiver range to approximately 1.5 km.

The new SSL Designer software, avail-able through Future Lighting Solutions at: www.futurelightingsolutions.com/ssldesigner takes the target light specifications such as the efficacy, illuminance, system lifetime, along with the maximum LED drive current as input parameters. It then determines the required minimum number of LEDs to meet the provided specifications. Moreover, it calculates the us-able light (lm), the usable efficacy (lm/W), andthe total power consumed by the LED-based system(W),amongstotheroutputparameters.

As shown in Figure 2(b), the SSL Designer hasconcluded that at a preset maximum current of 375mA due to the selected LED driver output current limitation, the LED-based low-bay lighting system requires 48 LUXEON Rebel LEDs to meet

Enabling Low-Bay Lighting Leveraging LED TechnologyBy Robert Zadeh, Technical Marketing Engineer, Future Lighting Solutions

Background on Low-Bay Lighting

Low-bay lighting is used in warehouse facilities, assembly areas, parking garages and workshop areas. All these applications typically require mounting heights of less than 3m.

HighIntensityDischarge(HID)lamps,HighPressure Sodium (HPS) lamps, fluorescent lamps and compact fluorescent lamps have been used until the recent years. Until the mid 2000s, the use of Light Emitting Diodes (LEDs) in general lighting applications such as street lighting, industrial factory floors and low-bay lighting was considered expensive and inconvenient. The reason was the inability of early LEDs to produce the required light output needed for such applications. As a result, it was considered costly to leverage the LED technology given the very high number of required LEDs.

Recent years have seen drastic changes in LED lighting technology. It is now possible to achieve flux values of 100+ lm from a single LUXEON® Rebel LED driven at 350mA and flux values of 200+ lm from the LUXEON® K2 with TFFC LED driven at 1000mA. Hence, higher light output can now be achieved using lower power and smaller LED count. Moreover, the average LED lifetimes have improved significantly. This makes LED technology an ideal solution for low-bay lighting applications.

This article focuses on the process of converting the existing low-bay lighting systems from con-ventional technologies to LED-based technology. The main goal is to meet the requirements such as light output, Correlated Color Temperature (CCT),efficacyandlifetime.Twopowersolutionswill be presented: The first one, referred to as the basic power solutions, corresponds to turning the LEDs on and off and to efficiently achieving lighting requirements. The second one, referred to as the intelligent power solutions, will give users the flexibility of adding sensors, wireless control, and dimming.

Achieving a LED-Based Low-Bay Lighting System

Future Lighting Solutions has developed a LED-based low-bay lighting system leveraging 48 LUXEON Rebel LEDs and Carclo Bubble Optics, as shown in Figure 1. This demo unit has been tested and simulated according to the specifications of Table 1.

Low-Bay Lighting Requirements

Since there are no official requirements on low-bay lighting performance available through ENERGY STAR for solid-state lighting, customer surveys have been conducted on the requirements oflow-baylighting,andhavebeensummarizedinTable 1. These parameters are used as a starting point in developing LED-based low-bay lighting system.

Meeting the Low-Bay Light Output Requirements

Generally, there are two options available when selecting the number of LEDs and the drive current. The first one involves producing high efficacy (lm/W) by using high number of LEDsat low drive currents. The second one involves producing high light output (in lm) by using lownumber of LEDs driven at higher currents, which result in lower efficacy values.

Basic Power Solutions

The basic power solution includes only ON/OFF functionality with no control or communications features.

Referring to the requirements of Table 1, a univer-sal LED driver is needed for powering the LEDs used in the low-bay light. The SSL1750 from NXP isanisolatedSwitchedModePowerSupply(SMPS)Controller Integrated Chip (IC), used to driveLEDs in low-bay lighting applications with power requirements of 25–250W. Figure 5 illustrates the evaluation board leveraging the SSL1750 IC.

The SSL1750 is fed by the 60-Hz universal ACmains (110–227V

AC).Withanefficiencyof85%andaPowerFactorCorrection (PFC)higher than0.95, the SSL1750 will facilitate an AC to AC step-down conversion. This will provide the constant current required by the LEDs.

Alternatively, a dual-stage AC-DC solution can be designed where the first stage will lever-age the SSL1750 in voltage mode to provide a constant output voltage of 48V

DC. The second stage will leverage four LM3402HV driver ICs from National Semiconductor to provide 4 constant current strings of 12 LEDs to drive the required 48 LEDs. Figure 6 illustrates the LM3402HV.

lighting application. However, the radiation pattern of the LEDs is lambertian which doesn’t provide a uniform illumination on the target surface.

In order to achieve a uniform illumination, the Carclo Bubble Optic (Part Number: 10403) hasbeen utilized for each LED as shown in Figure3(a). Its radiation pattern at a mounting heightof2.5misshown inFigure3(b).As thedistancefrom the center axis increases, the optic maintains the illumination level over the surface. The optical efficiency of this solution is greater than 90%, which maximizes the light output utilization andminimizestheLEDcount.

Thermal Solution

As shown in Figure 2(b), the SSL Designer hasdetermined that the 48 LUXEON Rebel LEDs must be driven at 375mA and the junction tempera-ture should not exceed 103°C to meet the target specifications, set by Table 1. Using the thermal simulation software QLED, the heat sink has been designedandoptimized.

Figure 4 illustrates the thermal distribution across the matrix of 48 LUXEON Rebel LEDs used in the low-bay light system. The maximum LED junction temperature in the model is calculated by QLED to be 104°C. This is an indication that the calculated resultsofFigure2(b)areaccurateandbelowthemaximum simulated value of junction temperature. This junction temperature is below the maximum rated value of 150°C for the LUXEON® Rebel LED.

It is important to note that the LED-based low-bay lighting fixture simulation shown in Figure 4 assumes a sealed enclosure that does not allow any ambient air in. In order to compensate for the heat generated inside the fixture, a high ambient temperature of 72.5°C has been entered into and has been used by the SSL Designer to calculate the resultsofFigure2(b).

the specifications. The power consumption of each LED is 1.11W. Using this system, the resulting efficacy is calculated to be 82.11 lm/W. The LED-based low-bay lighting system will have a total light output of 3940 lm and light efficacy of 62.82 lm/Wafteropticalandpower lossesof10%and15%,respectively.

The LED part number, lumen maintenance, circuit and heat sink details, and the efficiencies of optics and power solutions have been entered into the SSL Designer, as shown in Figure 2(a).Also, as shown in Figure 2(b), the LUXEON Rebel LEDs leveraged in the low-bay lighting system will be expected to perform 60,000 hours at maximum current of 375mA per LED, and average junction temperature of 103°C per LED. This is below the maximum rated value of 150°C for LUXEON Rebel, and therefore will attain 60,000 hours operation.

The(B50,L70) is interpretedas50%oftheLEDpopulation thatwill be less than the 70% lumenmaintenance criteria after 60,000 hours at the specified current and junction temperature.

ON Semiconductor’s NUD4700 LED Shunt technology facilitates open-circuit protection for LEDs connected in series. If one of the LEDs fails, the electric current would still pass through the path to the next LED in the strip.

Intelligent Power Solutions

Power solutions that facilitate more than just the basic capabilities for the LED-based low-bay lighting system are categorized under the “intelligent” alias. Features such as temperature sensing, motion sensing, ambient light sensing, power backup, wireless control and dimming can be added to low-bay lighting systems featuring LUXEON Rebel LEDs.

Power Programmable System on Chip (PowerPSoC®)

Cypress’s PowerPSoC® technology is a compre-hensive embedded system solution that combines an 8-bit microcontroller, flash memory, Static Random AccessMemory (SRAM)with program-mable analog and digital blocks, and a 4-channel LEDdriver,showninFigure7(a).Emergencybat-tery backup, ambient light and temperature sens-ing and wireless communications modules are be-ing added to and controlled by the PowerPSoC® microcontroller. The PowerPSoC® is the core com-ponent to implement all the mentioned intelligent features.

AsillustratedinFigure7(b),sensordaughtercardsused for motion, light, and temperature sensing can be implemented either for each fixture via a I2C communication link or remotely via a wireless communication link in order to send sensor signals to several fixtures at a time or to a central unit (i.e.computer).

output is directly connected to the circuitry that will leverage the measured temperature value in making the next decision of shutting down the circuit, dimming the LED accordingly, or continuing to drive the LED at the same current level.

Motion and Ambient Light Sensing

Ambient light sensors such as Avago’s APDS-9003 are used to detect light in the environment surrounding the LED-based low-bay lighting system. Supplied by 2.4–5.5V, they can be leveraged by the PowerPSoC in order to dim the LEDs if the ambient light is at high levels. Motion detectors, such as the NaPiOn Passive Infrared (PIR) from Panasonic can also be leveraged to help save power, and turn the light on when a per-son or an object enters the room or facility.

Using this sensor, the LED-based low-bay lighting system will go into “power saving mode,” where lightwouldbe30-50%dimmer.Upontheentranceof a person to the area, the motion detector would send signal via a wireless communications link to the LED-based low-bay light fixtures to return to100%lightoutput.Thiswillhelpinconserving energy and prolonging the lifetime of the LEDs being used in the low-bay light system.

Enabling Low-Bay Lighting Leveraging LED Technology (cont'd)

Emergency Battery BackupAs illustrated in Figure 7(b), the PowerPSoC® microcontroller core can be programmed to continuously charge the battery and to simultaneously drive the LEDs used in the low-bay lighting application.

UsingthecircuitofFigure7(b),2emergencyLEDsper12-LEDcluster(i.e.atotalof8outof48LEDs)will be powered by one 12V battery during a power outage. A minimum light output of a few lux will be available during the emergency for at least 3 hours of battery life.

Board Temperature Sensing

National Semiconductor’s LM75 provides 9-bit digital system-temperature sensing between -25 to 100°C and -55 to 125°C, depending on the operating conditions. The LM75 sensor will monitor the board temperature in order to protect the LEDs from thermal over-stress. It will be connected to the Power PSoC® board.

The LM75A supply voltage is 2.7-5.5V. This sensor doesn’t require additional external components and proves helpful in general thermal management and environmental monitor-ing of the LED-based low-bay light systems. The

Traditional lamps used in low-bay lighting proj-ects are being replaced by LEDs. Future Lighting Solutions has utilized numerous cutting edge solutions for LED-based low-bay lighting. An

Enabling Wireless Communications

Some LED-based low-bay lighting solutions may require wireless communications to control the low-bay lights or to receive information from the sensors. As illustrated in Figure 7(b), the men-tioned sensors will communicate with the fixture using either wireless or I2C methods, depending on the system design and requirements.

The ZigBee RF4CE standard implemented by Freescale has been primarily developed for consumer electronics, and for applications requiring device-to-device signal communications that do not necessarily need the full-featured mesh networking capabilities.

Using this standard, control signals from a maxi-mum of 8 master detectors can be detected and analyzed.Eachmasterdetectorisuniquelycodedand paired with the devices it controls. Therefore, intelligent LED-based low-bay lighting solutions are made possible via the ZigBee RF4CE wireless communication protocol.

Microchip Enables AC Measurement/ Metering with Product Line of ICsBy Mark Hofmann – Microchip Dedicated AE, Future Electronics

Microchip Technology, Inc., known for their industry leading 8-, 16-, and 32- bit micro-controllers, has introduced a line of products that can enable energy metering and energy measurement applications.

AC line power measurement, once relegated to utility meters, is finding applications in smart home/smart building and smart grid installations. Microchip Technology offers a range of metering solutions to fit your needs whether you are look-ing for a simple, cost effective way of measuring input power or if you are designing a Class 0.2 IEC compliant meter.

AC Power Metering Basics

Electronic meters are generally preferred over their mechanical counterparts due to more desirable attributes of the electronic system:

• Reliability• Accuracy - Non-linear loads - Ease of calibration• Automatedreading• Security• Advancedbilling - Net metering - Time of use

AC Power Measurement

Almost all power meters measure both voltage and current to calculate the power being delivered. The sum of this power over time is the energy that is con-sumed by the load. While measuring voltage in these systems is fairly straightforward, there is a decision to be made for measuring the current. Meters can either directly measure the current through a shunt or indirectly through the use of an isolation transformer. The tradeoffs of this decision of whether to use a shunt or transformer affects the design of the analog front end of the system. The shunt is essentially a piece of metal that acts as a sense resistor that can handle large currents. Typically this method is not usedinmeterswithamaximumcurrentof>100A.

The following figure shows the implementation of a shunt type power meter. This meter is designed with the microprocessor ground as the ‘hot’ of the AC. The power for both the Energy Meter IC and optional processor is derived from the AC line. There are four measurements points that connect to the AC line, two for the voltage divider and two for the shunt.

Meters using transformers can handle much more current than shunts and are more power effi-cient(usuallyenergycompaniesonlyallow2Wofpowerconsumptionforresidentialpowermeters). However, they are more expensive and can be less accurate due to the properties of the magnetics. (saturationandphaseresponse).

Microchip Devices

There are four different devices that Microchip offers for their energy metering applications: MCP3905A, MCP3905L, MCP3906A and MCP3909.

The Microchip energy metering devices have the following internal structure:

These devices are monolithic ICs that have two out-puts, one for real power measurement and one for instantaneous power measurement. Both of these outputs are proportional to the input power, with the instantaneous power giving a much higher fre-quency output. Both input channels use 16- bit, second-order, deltasigma ADCs that oversample the input at a frequency equal to MCLK/4, allow-ing for wide dynamic range input signals. Typically MCLK is between 1-4MHz, and acommon lowcost option is to use anNTSC 3.579MHz oscillator. AProgrammableGainAmplifier (PGA) increases theusable range on the current input channel and gain

can be changed from 1x to 32x. The calculation of the active power, and the filtering associated with this calculation are performed in the digital domain, ensuring better stability and drift performance. Two digital high-pass filters cancel the system offset on both channels such that the real-power calculation does not include any circuit or system offset. After be-ing high-pass filtered, the voltage and current signals are multiplied to give the instantaneous power signal. This signal does not contain the DC offset compo-nents, such that the averaging technique can be ef-ficiently used to give the desired active-power output.

The details of the differences are located in the following table:

Metering Implementations

The pulse outputs of the MCP3905/06/09 can directly drive electromechanical counters or two phase stepper motors. This allows these devices to work stand-alone in an installation. However when paired with a PIC microcontroller, there are greater opportunities for system flexibility. For instance, the MCP3905/06/09 devices con-nected to a PIC with an RTC allows for some advanced metering applications, such as time of use information. When coupled with a PIC and an integrated segmented LCD driver, the system allows greater communication between the user and the power being consumed. When connected to a PIC with an 802.11 module (Like the Silex SX-550),themetercouldthenattachtoawirelessnetwork and the user can see the power consump-tion in real time – either on their network or across the internet.
