The invention provides an integrated vehicle power converter and battery charger. In response to the voltage across the capacitor being greater than the voltage across the traction battery, the controller may turn off the switch such that charging current from the DC charger flows through the diode to the traction battery without following through the coil of the motor and through the inverter.
本公开提供了“集成式车辆电力转换器和电池充电器”。响应于跨电容器的电压大于跨牵引电池的电压,控制器可断开开关,使得来自DC充电器的充电电流通过二极管流到所述牵引电池,而不跟随通过电机的线圈并且不流过逆变器。
