ABSTRACT:
A system for driving a motor includes first and second rectifier circuits, a direct current (DC) link circuit, an inverter circuit, a voltage booster circuit, and a switch control circuit. When the motor is at a deceleration state, a micro control unit (MCU) outputs a first charging signal to turn on a switch of a first relay and turn off a switch of a second relay, a regenerative current from the motor is charged into a storage capacitor. Before the motor is in an acceleration state, the MCU outputs a second charging signal to turn on the switch of the second relay and turn off the switch of the first relay, and turn on a boosting switch, an increased voltage of the storage capacitor is charged into another storage capacitor. When a voltage at the DC link circuit reaches a predetermined value, the MCU controls the inverter circuit to accelerate the motor.
