Abstract

See full text

The present disclosure provides a power control system for motor preheating including a current sensor, a power calculation module, a power error calculation module, a power control module, a current control module and a voltage control module. The current sensor senses a motor current output by the motor. The power calculation module calculates an output power of the motor according to the voltage command and the motor current. The power error calculation module calculates a power error according to a power command and the output power. The power control module outputs a current braking command according to the power error. The current control module calculates a voltage command according to the current braking command and the motor current. The voltage control module outputs a three-phase voltage according to the voltage command, and the motor is operated in a stationary state, and the stator of the motor is preheated.
