The invention discloses a power conversion system integrating motor driving and battery charging and discharging. The power conversion system comprises an alternating current interface, a direct current interface, an AC/DC converter, a motor driver, a motor and a battery, the motor driver and the motor form a DC/DC converter; the first direct current end of the DC/DC converter is connected with the direct current end of the AC/DC converter; the second direct current end of the DC/DC converter is connected with the battery; the direct-current interface is connected with a first direct-current end of the DC/DC converter and is used for being externally connected with a direct-current power supply or a direct-current load; the AC interface is connected with the AC end of the AC/DC converter and used for being externally connected with an AC power grid or an AC load. Charging and discharging of the battery are realized by reusing the motor driver and the motor to form the DC/DC converter,the size, the cost and the weight of the charger can be greatly reduced, and multiple charging and discharging modes such as alternating current charging and discharging and direct current charging and discharging are supported.

    本发明公开了一种集成电机驱动和电池充放电的功率转换系统,该功率转换系统包括:交流接口、直流接口、AC/DC变换器、电机驱动器、电机和电池;其中,电机驱动器和电机组成DC/DC变换器;DC/DC变换器的第一直流端与AC/DC变换器的直流端连接;DC/DC变换器的第二直流端与电池连接;直流接口与DC/DC变换器的第一直流端连接,用于外接直流电源或直流负载;交流接口与AC/DC变换器的交流端连接,用于外接交流电网或交流负载。本发明通过复用电机驱动器和电机组成DC/DC变换器实现电池的充放电,能够大大降低充电机的体积、成本和重量,且支持交流充放电、直流充放电等多种充放电模式。
