Abstract
A vehicle includes an integrated power distribution module. The integrated power distribution module includes a hybrid transformer coupled to a charger stage, a traction battery, and an auxiliary battery. The hybrid transformer includes first and second primary windings coupled in series and connected to the charger stage. The primary windings have a corresponding first secondary winding coupling the traction battery via associated inverters. The primary windings further have corresponding second secondary windings that are coupled in series with opposing voltage polarities and coupled to the auxiliary battery via an associated inverter.
