产品概述
描述
The STEVAL-CTM014A has been designed to drive a 3-phase brushless DC motor up to 700 W typically of a washing machine appliance.
The circuit is composed of four parts: the control part, the compressor drive part, the auxiliary power supply circuit, and the communication circuit.
The control part uses STM32G431CB as the main control chip, which is mainly used to control motors. It also includes: current, voltage, temperature sampling, the realization of communication, overcurrent protection, over voltage protection, over temperature protection.
The compressor drive part includes a three-phase inverter circuit, lower bridge current sampling of IPM (current sampling is realized by STM32G431CB internal integrated operational amplifier).
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.
The VIPER122 integrates a switching power supply control chip and power MOSFET, and also has short-circuit protection functions. Mentioned functions simplify the design of the power supply and reduce the size of the power supply.
About the communication circuit, the STEVAL-CTM014A designs a single-line half-duplex serial communication circuit with isolation, this allows convenient communication with the washing machine control panel.
