2) DESCRIPTION
Figure 1-1-1 shows the basic principle of the SSFC. The 50/60 Hz mains voltage is converted into a galvanic isolated 3-phase, 400 Hz output voltage. A functional description of each part is provided in the following sections.
Figure - 1-1-1. Basic Principle
Input Disconnect (Q1)
The input disconnect removes all power to the ground power unit. On closing, the ground power unit starts up and enters standby mode.
RFI (Input)
Filter to reduce the EMC emission into the mains to such a level that surrounding equipment is not disturbed. In addition, the filter prevents voltage transients from reaching vital parts in the ground power unit.
Input Choke and 12-pulse Transformer (L1 / T1)
The combination of the choke, the 12-pulse transformer and the rectifier situated at the inverter module, ensures an almost sinusoidal line current and a power factor ~ 1. This means less stress on the main supply network and distribution transformers.

Solid State Converter
Chapter 1-1 June 15, 2013 Page 4
Inverter Module
Beside the rectifier and the DC-filtering capacitors, the module consists of a 3-phase inverter, which generates a 400 Hz voltage system with a very low harmonic content and individual phase control. Two PCBs (gate drives) are used to interface between the control unit and the thyristors/IGBTs. Voltage supervision of the DC-filtering capacitors is likewise performed at the gate drives.

June 15, 2013 Chapter 1-1 Page 5
Output Transformer (T2)
The output transformer secures galvanic separation between input and output. It also transforms the voltages from the inverter module into the required aircraft voltage (3 x 115/200 VAC). The filter choke for the output AC-filter is an integrated part of the transformer.
AC Filter Capacitors (C7-C9)
The harmonic content of the inverter voltage is further reduced by means of the AC Filter, resulting in a total voltage distortion of less than 2%. Complementing the filter choke (integrated in the transformer) and the AC capacitors, the ground power unit is equipped with an RFI-filter that reduces the high frequency emission from the ground power unit.
Output Contactor(s)
The ground power unit is equipped with one output contactor per cable. The contactor is engaged at start-up of the corresponding output, and it is disengaged, when the stop button is applied. If the interlock voltage, provided by the aircraft, is not returned to the ground power unit within 3 seconds, the contactor disengages.
Interface Module (A2)
The purpose of this module is to interface between the processor module and the rest of the ground power unit. The interface module includes the following functions:
• Interface to the display module (e.g., RS485, 24 VDC and EPO link).
• Pre-fuse for display module (F3).
• Measuring transformers for supervision of the utility power voltage.
• Measuring transformers for supervision of the 400 Hz output voltage.
• Interface for gate drives situated at the inverter module.
• Interface for current sensors situated at the inverter module.
• Relay control of fans situated at the inverter module.
• Relay control of output contactor(s).
• Input for temperature sensors.
• Pre-fuse of the 24 VDC for control purposes (F1-F2).
• I/O ports for remote control (Start, Stop etc.).
• Protected interface for interlock signals.
• Interface for individual overload protection.
• Neutral voltage supervision.
• Neutral conductor rupture supervision.
• Interface for RS232.

Solid State Converter
Chapter 1-1 June 15, 2013 Page 6
Supply Module (A5)
Beside the generation of a 24 VDC control voltage, the module includes fuses for AC-short circuit protection (F1-F3), MOVs (varistors) for facility power transient protection and a 10 A fuse (F4) for DC overload protection.
Processor Module (A1)
The processor module is based on a micro-controller and a digital signal processor (DSP). Together they regulate, supervise and diagnose eventual external and internal faults. As soon as the ground power unit is connected to the facility power, and constantly during normal operation, the processor module runs through a self-check program that checks all internal functions of the ground power unit. If an internal or external error is detected, the display shows the nature of the error. All immediate parameters related to a shutdown are stored in the ground power unit’s memory.
Display Module and Keyboard (A3 / A4)
The display module serves as the interface for daily operation. RS485 communication allows the display module to be positioned up to 1 kilometer (0.62 miles) away from the ground power unit.

CHAPTER 1 - Description/Operation
Section 3 - Preparation, Adjustment, and Maintenance
1) STORAGE BEFORE INSTALLATION
To secure optimal storage conditions prior to installation, it is recommended that the converter be stored inside to protect it from rain and excessive humidity while it is left without power on.
Only equipment in seaworthy packing can be stored outside.
2) OPERATIONAL AND ENVIRONMENTAL CONDITIONS AFTER COMMISSIONING
When the converter has been installed and commissioned, we recommend the input always be kept with input power ON to provide optimal conditions for the electronic components and to avoid humidity in the form of condensation from reaching vital parts.
If for some reason the converter has been without input voltage for a long period, a visual inspection should be carried out. In case that condensation is discovered on any internal parts, the parts have to dry out before input voltage is again applied.
3) MOUNTING OF BOTTOM FILTER
Due to transport safety, models may be delivered without the filters mounted to facilitate the means of the accompanying mounting devices. The filters should be installed before powering up the converter.
WARNING
FOR FIRE SAFETY REASONS, THE UNIT IS NOT TO BE INSTALLED ON A COMBUSTIBLE SURFACE.

8) UTILITY POWER
The correct phase sequence is ABC. The SSFC ground power unit is equipped with automatic phase sequence detection. The detection is automatically carried out when the utility power is turned on. If the phase sequence is incorrect, an error message will display. Correction is made by reversing two phases.
9) 400 HZ OUTPUT
At delivery, the 400 Hz neutral is connected to the ground (PE) terminal. If a floating output is required, the yellow/green connection wire must be removed.
10) 400 HZ INTERLOCK
The interlock safety system ensures the output contactor stays engaged as long as the aircraft connector is inserted into the aircraft receptacle. The aircraft provides 28 VDC on the F terminal with respect to the 400 Hz neutral terminal.
Figure - 1-3-7. Standard wiring diagram for civil aircraft
For service, maintenance and test purposes, the interlock system can be bypassed via the display setup. To ensure personal health and safety, the ground power unit automatically returns to its initial interlock mode once it receives 28 VDC at the F terminal, e.g., when the ground power unit is connected to an aircraft.
WARNING
DUE TO PERSONAL HEALTH AND SAFETY, THE SSFC UNIT MUST ALWAYS BE PROTECTED BY GROUNDING THE

Chapter 1-4 June 15, 2013 Page 8
11) MANUAL CABLE COMPENSATION
This is the traditional (Manual) method of cable compensation, where the output voltage is increased in proportion to the load current (1 Volt / 100 A). This method can be used when banded cable(s) are used or the voltage changes caused by unbalanced loads or varying power factor loads can be ignored.
1. Apply nominal load at the aircraft connector.
2. Select compensation type to “MANUAL” via Setup Mode.
3. Select “CABLE COMP. OUTPUT 1”.
4. Adjust the compensation by means of the vertical arrow buttons until the voltage at the aircraft connectors equals the no load value.
If the ground power unit is equipped with a second outlet, the same procedure is applied for “OUTPUT 2”.
12) NORMAL OPERATION
e. The operation of the SSFC is carred out via the switches located on the front panel. Table 1-4-4 lists the option of using a remote control panel box during normal operation.
CAUTION
THE E/F INTERLOCK CIRCUIT IS DESIGNED TO FUNC-TION BY RECEIVING +28VDC FROM THE AIRCRAFT ON THE OUTPUT CABLE F-PIN. IF THE AIRCRAFT DOES NOT PROVIDE +28 VDC, THE OUTPUT CONTACTOR WILL BE INOPERABLE UNLESS THE INTERLOCK BYPASS SWITCH IS ACTIVATED.
CAUTION
BEFORE PERFORMING NORMAL OPERATION, ENSURE THE PRE-OPERATIONAL PROCEDURES AND START-UP PROCEDURES HAVE BEEN PERFORMED.

CHAPTER 2 - Troubleshooting and Repair
Section 1 - Troubleshooting and Repair
Usually the display text provides sufficient information to get the ground power unit into operation again. In case the display is blank, please check fuse F1, F2 and F4 at the Supply Module A5 and fuse F3 at the Interface Module A2.
If the displayed text does not provide sufficient information to solve the problem, Table 2-1-1 and Table 2-1-2 suggest prioritized corrective actions to be carried out for each error code.
Additional error-information regarding the input voltage, output voltage, transformer filter current, overload and short circuit can be derived from the error code according to the following directions:
Error Code XX01 refers to output phase A (or input phase L1) Error Code XX02 refers to output phase B (or input phase L2) Error Code XX03 refers to output phase A and B (or input phase L1 and L2)Error Code XX04 refers to output phase C (or input phase L3) Error Code XX05 refers to output phase A and C (or input phase L1 and L3)Error Code XX06 refers to output phase B and C (or input phase L2 and L3)Error Code XX07 refers to all output phases (or all input phases)
Examples: Error Code 1001 refers to a too high input voltage at phase L1. Error Code 4007 refers to overload at all 3 output phases.
WARNING
DISCONNECT SUPPLY BEFORE CHANGING ANY FUSE. FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE AND RATING FUSE.

CHAPTER 3 - Overhaul / Major Repair
Section 1 - Overhaul / Major Repair
1) GENERAL
Repair of the converter consist primarily of part replacement. Most of the components used in the converter cannot be disassembled and repaired, and must be replaced if faulty. Additionally, inoperative PC boards cannot be repaired in the field and must be replaced as a complete unit. PC boards may be returned to the factory for replacement. Contact Hobart Ground Systems for part and replacement instructions.
2) SERVICE INFORMATION AND FACTORY REPAIR
Questions concerning the operation, repair, and/or servicing of this converter should be directed to the Service Department of Hobart Ground Systems. When making such an inquiry, be sure to provide the Service Department with the model number, serial number, and approximate date of receipt of the unit. If it is deemed necessary to return the unit to the factory for servicing, contact the Customer Service Department for authorization. It is rarely necessary to return a failed converter since the unit uses modular components and plug-in type assemblies throughout the converter. For warranty information, refer to the warranty statement at the front of this manual or contact the Hobart Service Department.
When ordering parts from your Hobart Ground Systems Distributor, be sure to include all pertinent information from the unit’s identification plate: Specification No., Model No., and unit rating. If you have any questions concerning your Hobart Ground Systems equipment, immediately contact our Service Department by mail, telephone, Email or FAX. See Contacting Customer Service on page xviii of this manual for Customer Service contact information.
3) TEST EQUIPMENT AND SPECIAL TOOLS
Table 3-1-1 lists the test equipment and special tools required for performing maintenance and testing of the facility power converter. Equivalent tools and test equipment can be used.
CAUTION
TO MAKE CERTAIN THAT THE UNIT IS ALWAYS READY FOR USE, IT MUST BE MAINTAINED ON A REGULAR BASIS. ONLY HAVE QUALIFIED PEOPLE REMOVE COV-ERS FOR SERVICE, MAINTENANCE OR OVERHAULS.

• Check rubber gasket at front door, rear panel and top cover. Yearly
• Check internal bolt/screw and wire connections. Yearly
• Check vibration dampers (via rear panel). Yearly
• Visual inspection of PCBs - control unit / gate drive. Yearly
• Control of the output contactors' contact sets and coil. Yearly
• Control of output voltage at aircraft connector (with and without load). Yearly
Mobile units
• Check tires for wear and tear. Yearly
• Check correct air pressure (4,3 Bar = 62 PSI). Quarterly
5) BATTERY BACK-UP
Situated on the processor board, a lithium battery ensures that Setup data etc. are not lost during utility power drop-outs. The expected life of the battery is approximately 10 years. However, a low battery voltage does not affect the internal safety system of the GPU that monitors the output voltage, among others. Thus aircraft connected to the GPU are not exposed to any danger. To avoid loss of data we recommend to change the battery after 8 to 9 years of use.

AP 578910Neutral Conductor Rupture (NCR) Supervision
A broken neutral conductor in the 400 Hz cable combined with an unbalanced aircraft load could lead to a destructive phase-neutral voltage in the aircraft and to hazardous voltages between the aircraft chassis and the ground level. The NCR option secures that a broken neutral will be detected instantaneously.
Figure A-3. NCR Board and Internal wiring diagram

June 15, 2013 Appendix A Page 5
Figure A-4. Wiring diagram for Neutral Conductor Rupture Supervision
Unbalanced voltage at the aircraft connector due to a broken neutral would add a 400 Hz voltage to the 28 VDC interlock voltage measured at the ground power unit. If the injected AC voltage exceeds approx. 20 VAC the output is disconnected. This type of error is recognized as an interlock failure by the ground power unit. Since the disconnection is a reaction against a heavy unbalanced voltage at the aircraft connector, it means that this type of supervision does not protect sensitive equipment in the aircraft. The NCR option protects personnel as well as the aircraft in case of a broken neutral.
