Product Overview
STEVAL-CTM014A is a 700W reference design designed to drive a 3-phase brushless DC motor up to 700W typically of a washing machine appliance. The circuit is composed of 4 parts: control, compressor drive, auxiliary power supply circuit and communication circuit. The control uses STM32G431CB as main control chip mainly used to control motors. It also includes current, voltage, temperature sampling, the realization of communication, overcurrent protection, OVP, OTP. The compressor drive part includes a 3-phase inverter circuit, lower bridge current sampling of IPM (current sampling is realized by STM32G431CB internal integrated op-amp). The three-phase inverter bridge adopts STGIPQ8C60T-HZ intelligent power module. The STGIPQ8C60T-HZ includes six IGBTs and gate drive circuits, as well as NTC temperature sampling and overcurrent comparison circuits. The auxiliary power supply circuit includes transformer, switching power supply controller, power switch tube, rectifier diode, etc.
