A power converter (100) comprises a pair of resonant converter circuits 112-115, 132, 136, 138, 146 and 116-119, 134, 142, 144, 148) 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 (112-115, 132, 146, 136, 138) includes at least one power switch (112, 114) adapted to convey power to a first resonant circuit (132, 146, 136, 138) and a first rectification (152, 154) stage adapted to rectify the conveyed power from the first resonant circuit. The second resonant converter circuit (116-119, 134, 148, 142, 144) includes at least one power switch (116, 118) adapted to convey power to a second resonant circuit (134, 148, 142, 144) and a second rectification stage (156, 158) adapted to rectify the conveyed power from the second resonant circuit. A filter capacitor (162) is coupled to the first and second rectification stages to provide DC output power therefrom. A regulator (126) is operatively coupled to the first and second resonant converters to control. |
