For use in a power converter having a controlled full bridge coupled to a transformer, the bridge delivering power received from an input of the power converter to a primary winding of the transformer, a circuit for, and method of decreasing conducted and radiated electromagnetic interference of the power converter. In one embodiment, the circuit includes a switching circuit, coupled across at least a portion of the primary winding, that closes to short the portion as a function of a state of the full bridge to stabilize a voltage level of the primary winding and reduce ringing caused by the intrinsic capacitance, thereby decreasing the conducted and radiated electromagnetic interference.
