An example of a vehicle electrical system includes a rechargeable energy storage system (RESS) having a first voltage and a power inverter electrically connected to the RESS. The system also includes an electric motor having a plurality of motor windings, wherein each motor winding includes a multi-phase terminal electrically connected to the power inverter. The motor also includes a neutral terminal disposed separately from the multi-phase terminal. The system also includes an accessory load connected to the power inverter and a neutral terminal of the motor, wherein the accessory load requires a second voltage lower than the first voltage. A current flows through the motor winding to reduce the first voltage to a second voltage. The power inverter is configured to cycle between the first and second operating states such that the power inverter reduces the first voltage to the second voltage.
车辆电气系统的示例包括具有第一电压的可再充电能量存储系统(RESS)和电性连接至RESS的功率逆变器。该系统还包括具有多个电机绕组的电动机，其中每个电机绕组包括电性连接至功率逆变器的多相端子。电动机还包括与多相端子分开设置的中性端子。该系统还包括连接至功率逆变器和电动机的中性端子的附件负载，其中所述附件负载需要的第二电压低于所述第一电压。电流流过电机绕组以将第一电压降低到第二电压。功率逆变器被配置为在第一和第二操作状态之间循环，使得功率逆变器将第一电压降低到第二电压。
