SLLIMM™ - 2nd series IPM, 3-phase inverter, 20 A, 600 V short-circuit rugged IGBTs ST’s SLLIMM™ family of small low-loss intelligent molded modules enhances the efficiency of home appliance motor drives working up to 20 kHz in hard-switching circuitries and of applications with a power range up to 3 kW. ST’s intelligent power modules (IPMs) provide a direct connection between a low-voltage microcontroller and a mains-powered electric motor. They greatly reduce costs by simplifying design and significantly reducing component count while saving space, improving reliability and lowering EMI. Available in several package options (fully molded and DBC), current ratings and driving options, they feature the best compromise between conduction and switching losses, along with outstanding robustness and EMI behavior. STGIB15CH60TS-L主要特点: 3A-5A current rating at 25℃, with 600V breakdown voltage; STGIB15CH60TS-L应用: • 3-phase inverters for motor drives 马达控制电源板STEVAL-IPM15B 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 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. 马达控制电源板STEVAL-IPM15B主要特点: Input voltage: 125 - 400 VDC |
