Abstract
A system includes an inverter configured to convert DC power from a main battery to AC power to drive a motor, wherein the inverter includes a galvanic isolator separating a high voltage (HV) area from a low voltage (LV) area, a gate driver in the HV area, the gate driver to control one or more switches in the HV area in response to a control signal from the LV area, an auxiliary battery assembly in the HV area, and a power supply to provide power to the HV area from each of the main battery and the auxiliary battery assembly.
