STEVAL-IPM20B

The STEVAL-IPM20B is a compact motor drive power board equipped with the SLLIMM (small low-loss intelligent molded module) 2nd series module STGIB20M60TS-L. It provides an affordable, easy-to-use solution for driving high power 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 for motor drives.

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

The main characteristics of this evaluation board are its small size, minimal BOM and high efficiency. It consists of an interface circuit (BUS and V_CC connectors), bootstrap capacitors, snubber capacitor, hardware short-circuit protection, fault event signal and temperature monitoring. It is designed to work in single or three-shunt configuration and with two current sensing options: three dedicated op-amps on the evaluation 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 feedback to satisfy the typical requirements for field-oriented control (FOC).

The STEVAL-IPM20B is compatible with ST control boards based on STM32 microcontrollers, providing a complete platform for motor control.
