Abstract:
A motor vehicle has a high-voltage battery and two separate electric machines. Each electric machine is associated with a power electronics unit, and each power electronics unit has a DC-to-DC converter. Each DC-to-DC converter is designed to reduce a high voltage of the high-voltage battery to a predetermined voltage. The two DC-to-DC converters of the two power electronics units are connected electrically in parallel and are set to different voltage values.
