Abstract: A power integration system with motor drive and battery charging and discharging function includes a motor, a power integration circuit, and a battery. The power integration circuit includes an inverter and a charger. The inverter includes multi-phase bridge arms, and each bridge arm has an upper switch and a lower switch. Each bridge arm is correspondingly coupled to each phase winding of the motor. The charger includes a front-end DC conversion path, and the upper switch and the lower switch of at least one bridge arm of the shared inverter. The battery is coupled to the power integration circuit. The power integration circuit receives a DC power provided by a DC power apparatus, and the charger converts the DC power to charge the battery. The battery provides the power required to drive the motor by the inverter.

Abstract: A power integration system with motor drive and battery charging and discharging function includes a motor, a power integration circuit, and a battery. The motor includes multi-phase paths, and each path has an inductor. The power integration circuit includes an inverter and a charger. The inverter includes multi-phase bridge arms, each bridge arm has an upper switch and a lower switch, and each bridge is correspondingly coupled to each inductor of the motor. The charger a switch, the upper switch and the lower switch of at least one bridge arm of the shared inverter, and the inductor of the shared motor. The switch is coupled between any two bridge arms. The power integration circuit receives a DC power provided by a DC power apparatus, and the charger converts the DC power to charge the battery, and the battery provides power required to drive the motor through the inverter.

Abstract: A power integration system with motor drive and battery charging and discharging function includes a motor, a power integration circuit, and a battery. The power integration circuit includes an inverter and a charger. The inverter includes multi-phase bridge arms, and each bridge arm has an upper switch and a lower switch. Each bridge arm is correspondingly coupled to each phase winding of the motor. The charger includes a charging unit having at least a switch, an inductor, or a diode and the upper switch and the lower switch of at least one bridge arm of the shared inverter. The power integration circuit receives a DC power provided by a DC power apparatus, and the charger converts the DC power to charge the battery. The battery provides the required power of driving the motor through the inverter.
