Abstract
A system comprises a high voltage (HV) battery system connected to an HV bus, a motor generator unit (MGU) connected to the HV bus, a main contactor disposed on the HV bus between the MGU and the HV battery system such that, when the main contactor is closed, the HV battery system stabilizes a voltage of the HV bus, a low voltage (LV) battery system connected to an LV bus and configured to stabilize a voltage of the LV bus when the main contactor is open or malfunctioning, a direct current to direct current (DC-DC) converter connected to the HV bus and the LV bus, and a controller configured to (i) when the main contactor is closed, control the DC-DC converter to stabilize the LV bus voltage, and (ii) when the main contactor is open or malfunctioning, control the DC-DC converter to stabilize the HV bus voltage.
