Features

• Input voltage: 125 - 400 VDC• Nominal power: up to 2000 W

– Allowable maximum power is related to the application conditions andcooling system

• Nominal current: up to 12 Arms

• Input auxiliary voltage: up to 20 V DC• Single- or three-shunt resistors for current sensing (with sensing network)• Two options for current sensing: dedicated op-amps or through MCU• Overcurrent hardware protection• IPM temperature monitoring and protection• Hall sensor or encoder input• IGBT intelligent power module:

– SLLIMM™ 2nd series IPM (STGIB20M60TS-L - DBC package)• Motor control connector (32-pin) to interface with ST MCU boards• Universal conception for further evaluation with breadboard and testing pins• Very compact size• WEEE compliant• RoHS compliant

DescriptionThe STEVAL-IPM20B is a compact motor drive power board equipped with theSLLIMM (small low-loss intelligent molded module) 2nd series moduleSTGIB20M60TS-L. It provides an affordable, easy-to-use solution for driving highpower motors for a wide range of applications such as white goods, air conditioners,compressors, power fans, high-end power tools, and generally 3-phase inverters formotor drives.

The IPM itself consists of short-circuit rugged IGBTs and a wide range of featuresincluding undervoltage lockout, smart shutdown, temperature sensing and NTCinside, and overcurrent protection.

The main characteristics of this evaluation board are its small size, minimal BOM andhigh efficiency. It consists of an interface circuit (BUS and VCC connectors), bootstrapcapacitors, snubber capacitor, hardware short-circuit protection, fault event signaland temperature monitoring. It is designed to work in single or three-shuntconfiguration and with two current sensing options: three dedicated op-amps on theevaluation board, or op-amps available on a connected microcontroller. A Hall/Encoder section completes the circuit.

The system is designed to achieve accurate and fast conditioning of current feedbackto satisfy the typical requirements for field-oriented control (FOC).

The STEVAL-IPM20B is compatible with ST control boards based on STM32microcontrollers, providing a complete platform for motor control.
