The invention provides an energy conversion system and a power system, the energy conversion system comprises a motor, a control module, an AC/DC conversion module, a first switch, a plurality of other switches and a plurality of filter inductors, and first connecting ends of the plurality of filter inductors are connected to a plurality of first connecting ends of a three-phase AC power supply through the plurality of other switches. Under the condition that the motor is driven and the battery module is charged at the same time, the control module can be used for controlling the first switch to be switched off, controlling the other switches to be switched on or switched off, and controlling the first bridge arm switch and the second bridge arm switches to act. Therefore, the purpose of driving the motor and charging the battery module based on the AC voltage provided by the three-phase AC power supply is achieved. In the application, the first switch, the other switches and the bridge arm switches can be controlled to work cooperatively, so that the purposes of simultaneously driving the motor and charging the battery module are achieved, the energy conversion efficiency is further improved, the cost is low, and the applicability is high.

    本申请提供了一种能量转换系统及动力系统,该能量转换系统中包括电机、控制模块、AC/DC变换模块、第一开关、多个其他开关和多个滤波电感,其中多个滤波电感的第一连接端通过多个其他开关连接至三相交流电源的多个第一连接端。在同时驱动电机且对电池模块充电的情况下,控制模块可用于控制第一开关断开、多个其他开关中的各其他开关导通或者关断,并控制第一桥臂开关和多个第二桥臂开关中的各桥臂开关动作,从而实现基于三相交流电源提供的交流电压驱动电机并对电池模块充电的目的。在本申请中,可控制第一开关、各其他开关以及各桥臂开关配合工作,从而达到同时驱动电机且对电池模块充电的目的,进而提高了能量转换效率,成本低,适用性强。
