The STEVAL-IPM15B is a compact motor drive power board based on the SLLIMM™
(small low-loss intelligent molded module) 2nd series module STGIB15CH60TS-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 Vcc connectors), bootstrap capacitors, snubber capacitor, hardware shortcircuit protection, fault event signal and temperature monitoring. In order to increase
its flexibility, it was designed to work in single or three-shunt configuration and with
double current sensing options such as three dedicated op-amps on-board, or opamps embedded on the MCU. A Hall/Encoder part completes the circuit. Thanks to
these advanced characteristics, the system has been specifically designed to
achieve accurate and fast conditioning of the current feedback, matching the typical
requirements for field-oriented control (FOC). The STEVAL-IPM15B is compatible
with ST’s STM32-based control board, providing a complete platform for motor
control.
