Zusammenfassung:	An apparatus, system and method for an electrical vehicle, EV, three level inverter motor drive circuit (500, 600) with an integrated battery charger. The apparatus, system and method may include a direct current, DC, battery (512, 606) for the EV connected in parallel with a first and a second capacitance; wherein the first capacitance and the second capacitance are connected in series, and a middle node between the two capacitances is referred to as a neutral point; and a three level inverter circuit in parallel with the DC battery (512, 606) and connected to the neutral point, comprising: a high frequency low voltage pulse width modulation circuit (502); and a low frequency fundamental switching circuit (504) at least partially in parallel with the high frequency low voltage pulse width modulation circuit (502). Additionally included may be motor windings (510, 614) connected with the low frequency fundamental switching circuit (504); and a power factor correction boost charging circuit (506) connected to the three level inverter circuit, and connected to an alternating current grid (508, 612).
