Abstract
An apparatus, system and method for a multilevel electrical vehicle (EV) motor drive circuit with an integrated battery charger. The apparatus, system and method may include a direct current (DC) battery for the EV connected in parallel with a capacitance; and a three level inverter circuit in parallel with the DC battery and connected in neutral point bisection with the capacitance, comprising: a high frequency low voltage pulse width modulation circuit; and a low frequency fundamental switching circuit at least partially in parallel with the high frequency low voltage pulse width modulation circuit. Additionally included may be motor windings connected in neutral point bisection with the low frequency fundamental switching circuit; and a power factor correction boost charging circuit connected to the three level inverter circuit, and connected to an alternating current grid.
