Compact magnetics assembly

摘要

A magnetic assembly to receive current having a high current and high frequency includes a transformer, at least one resonant inductor, and at least one auxiliary inductor. The resonant inductor is in electrical communication with the transformer, and the auxiliary inductor is in electrical communication with the resonant inductor. The magnetic assembly further includes at least one conductor having a first end coupled to the auxiliary inductor and a second end coupled to the transformer. The conductor extends continuously between the first and second ends without terminating to form an auxiliary winding of the auxiliary inductor, a resonant winding of the resonant inductor, and at least one primary winding of the transformer.
