In at least one embodiment, a vehicle battery charger is provided. At least one transformer includes a first winding and a second winding on a primary side of the transformer that are connected to one another to form a middle point. The middle point of the at least one transformer receives an input voltage signal from a mains supply. A half-bridge rectifier receives the input voltage signal from the mains supply to enable the middle point of the least one transformer to receive the input voltage signal from the mains supply. A first active bridge includes a first plurality of switching devices to receive a first input signal directly from the first winding and to receive a second input signal directly from the second winding. The first input signal and the second input signal are out of phase with one another to minimize electromagnetic interference within the vehicle battery charger.
