1000W馬達控制電源板STEVAL-IPM10F

The STEVAL-IPM10F is a compact motor drive power board based on SLLIMM? （small low-loss intelligent molded module） 2nd series （STGIF10CH60TS-L）。 It provides an affordable and easy-to-use solution for driving high power motors for a wide range of applications such as power white goods， air conditioning， compressors， power fans， high-end power tools and 3-phase inverters for motor drives in general. The IPM itself consists of short-circuit rugged IGBTs and a wide range of features like undervoltage lockout， smart shutdown， embedded temperature sensor and NTC， and overcurrent protection.

The main characteristics of this evaluation board are 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 and temperature monitoring. In order to increase the flexibility， it is designed to work in single- or three-shunt configuration and with double current sensing options such as using three dedicated onboard op-amps， or op-amps embedded in the MCU. The Hall/Encoder part completes the circuit. Thanks to these advanced characteristics， the system has been specifically designed to achieve fast and accurate current feedback conditioning， satisfying the typical requirements for field-oriented control （FOC）。

The STEVAL-IPM10F is compatible with ST ’s STM32-based control board， enabling designers to build a complete platform for motor control.
