A vehicle includes a system for charging a battery of the vehicle. The system includes an electric motor coupleable to a charging station, a capacitor-clamped multilevel inverter, and a processor. The capacitor-clamped multilevel inverter couples the electric motor to the battery and includes a first leg having a first set of switches and a first AC terminal coupled to the electric motor, a second leg having a second set of switches and a second AC terminal coupled to the electric motor, and a third leg having a third set of switches and a third AC terminal coupled to the electric motor. The processor connects one of the third AC terminal and the neutral point of the electric motor to the charging station and controls at least one of the first set of switches and the second set of switches to charge the battery through the electric motor.
车辆包括用于对车辆的电池充电的系统。该系统包括可联接到充电站的电马达、电容器钳位多电平逆变器和处理器。电容器钳位多电平逆变器将电马达联接到电池,并且包括具有第一组开关和联接到电马达的第一AC端子的第一支路、具有第二组开关和联接到电马达的第二AC端子的第二支路、以及具有第三组开关和联接到电马达的第三AC端子的第三支路。处理器将电马达的第三AC端子和中性点中的一个连接到充电站,并控制第一组开关和第二组开关中的至少一个以通过电马达对电池充电。
