An electrical system for use with an AC power supply having multiple phase voltages, e.g., three phase voltages, may include a high-voltage battery pack or other high-voltage DC device, a 12 VDC battery or other auxiliary-voltage DC device providing auxiliary power to the electrical system, multiple AC-DC converters, and a controller. The AC-DC converters each provide a DC output voltage to the high-voltage DC device, and are operable for converting a respective one of the phase voltages from the AC power supply into the DC output voltage. The controller selectively disables the AC-DC converters in response to a detected predetermined operating condition to thereby reduce consumption of the auxiliary power within the electrical system. A vehicle may include a high-voltage DC battery pack, an auxiliary-voltage DC battery providing auxiliary power, an onboard charging module, a charging port, an auxiliary power module, an electric machine, and a controller.
An electrical system for use with an alternating current (AC) power supply having multiple phase voltages, the electrical system comprising:
A vehicle for use with a three-phase alternating current (AC) power supply, the vehicle comprising:
A method for reducing consumption of auxiliary power within an electrical system configured for use with an alternating current (AC) voltage supply having multiple phase voltages, wherein the electrical system includes a high-voltage direct current (DC) device, an auxiliary-voltage DC device providing auxiliary power to the electrical system, and a plurality of AC-DC converters each providing a DC output voltage to the DC device, wherein each AC-DC converter is operable for converting a respective phase voltage from the AC voltage supply into the DC output voltage, the method comprising:
