Description
The STEVAL-IPM15B is a compact motor drive
power board based on the SLLIMM™ (small low-
loss intelligent molded module) 2
nd
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 short-circuit 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 op-amps
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.
