A power converter comprises a pair of resonant converter circuits coupled together in parallel and operated at respective switching frequencies that are out of phase. The power converter includes a first resonant converter circuit and a second resonant converter circuit operatively coupled together. The first resonant converter circuit includes at least one power switch adapted to convey power to a first resonant circuit and a first rectification stage adapted to rectify the conveyed power from the first resonant circuit. The second resonant converter circuit includes at least one power switch adapted to convey power to a second resonant circuit and a second rectification stage adapted to rectify the conveyed power from the second resonant circuit. A filter capacitor is coupled to the first and second rectification stages to provide DC output power therefrom. A regulator is operatively coupled to the first and second resonant converters to control switching frequency of the power switches, such that the switching frequency of the at least one power switch of the second resonant converter is shifted in phase with respect to the switching frequency of the at least one power switch of the second resonant converter. In a preferred embodiment, the switching frequency of the at least one power switch of the second resonant converter is shifted in phase by approximately 90 with respect to the switching frequency of the at least one power switch of the second resonant converter.
