The invention relates to a power conversion circuit, a vehicle power conversion system and a vehicle. The power conversion circuit comprises a first switch assembly and a second switch assembly, wherein a plurality of first ends of the first switch assembly are correspondingly connected with an alternating current input interface and an air conditioner compressor respectively; the input end of the power module is connected with the second end of the first switch assembly; the first end of the second switch assembly is connected with the output end of the power module, and the two second ends of the second switch assembly are correspondingly connected with the voltage conversion module and the power battery respectively; the voltage conversion module is connected with the power battery. By controlling the connection state of the first switch assembly and the second switch assembly, the circuit connection relation in the vehicle power conversion system is changed, so that the power module can be used as a part of a charging and discharging circuit of a power battery and can also be used as a part of a driving circuit of an air conditioner compressor, and the cost of the whole vehicle is reduced.
本申请涉及一种功率变换电路、车辆功率变换系统及车辆。该功率变换电路包括:第一开关组件,第一开关组件的多个第一端分别与交流输入接口和空调压缩机对应连接;功率模块,功率模块的输入端与第一开关组件的第二端连接;第二开关组件,第二开关组件的第一端与功率模块的输出端连接,第二开关组件的两个第二端分别与电压转换模块和动力电池对应连接;电压转换模块与动力电池连接。通过控制第一开关组件和第二开关组件的连通状态,改变车辆功率变换系统中的电路连接关系,使得功率模块既可作为动力电池的充放电电路的一部分,也可作为空调压缩机的驱动电路的一部分,降低了整车成本。
