An automotive power system includes a circuit arrangement including an AC input, an AC/DC power converter, an electromagnetic interference filter connected between the AC input and AC/DC power converter, a transformer, a first switching bridge connected between the AC/DC power converter and transformer, and a switch bank connected with a secondary side of the transformer that connects the secondary side with a second switching bridge such that the second switching bridge is connected between a traction battery and the transformer, and the switching bridges and transformer form an isolated DC/DC power converter. The system also includes one or more switches that directly connect the traction battery between the AC input and electromagnetic interference filter.
