Abstract
A system for an electrified vehicle, such as a battery electric vehicle (BEV), includes an inverter configured to drive a motor having motor windings with electrical power from a battery according to a configuration of a power switch of the inverter. The system further includes a capacitor connected between a center-tap of the battery and a neutral-point of the motor winding whereby the capacitor and the motor windings form an LC circuit. The system further includes a controller configured to operate the power switch in a zero-current-switching mode with a switching frequency dependent on a resonant frequency of the LC circuit to thereby cause electrical current to circulate between the battery, the inverter, and the motor which heats the battery and the motor windings.
