Abstract: A control method applied to a power supply system. The power supply system comprises at least one first power unit and a second power unit, and the at least one first power unit is configured to provide power to an electrical load according to a power provided by a power source. The control method comprises: detecting a load status of the power supply system; when the load status is determined to be a peak load, generating a trigger signal; and in response to the trigger signal, disabling a first-stage converter in the second power unit, and controlling an energy storage capacitor in the second power unit to provide power to the electrical load, wherein the energy storage capacitor is coupled between the first-stage converter and a second-stage converter in the second power unit.

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.
