(3)变频器总成。变频器的功用是将HV蓄电池的高压直流电转换为三相交流电来驱动MG1和MG2。此外,变频器也用于将电流控制(如输出电流或电压)的信息传输到HV ECU(混合动力汽车控制单元)。
(3) inverter assembly. The function of the frequency converter is to convert the high voltage direct current of the HV battery into three-phase alternating current to drive MG1 and MG2. In addition, the frequency converter is also used to transmit information of current control (eg output current or voltage) to the HV ECU (Hybrid Vehicle Control Unit).
