The present disclosure provides a motor inverter based converter for charging a traction battery. The inverter is electrically connected between the traction battery and the switching group. The inverter includes a plurality of pairs of power semiconductor devices connected in series. Each of the plurality of pairs is electrically connected in parallel with the traction battery to define a phase bridge, and each of the power semiconductor devices has a body diode in parallel therewith. The inverter also includes a plurality of diodes connected in parallel with the power semiconductor devices such that only one of the power semiconductor devices of each of the plurality of pairs has one of the diodes connected in parallel therewith.
