Abstract:
1. A power converter comprising: a first resonant converter circuit including at least one power switch adapted to convey power to a first resonant circuit and a first rectification stage adapted to rectify said conveyed power from said first resonant circuit; a second resonant converter circuit including at least one power switch adapted to convey power to a second resonant circuit and a second rectification stage adapted to rectify said conveyed power from said second resonant circuit; a filter capacitor coupled to said first and second rectification stages to provide DC output power therefrom; a regulator operatively coupled to said first and second resonant converters to control switching frequency of said at least one power switch of each of said first and second resonant converters, such that switching frequency of said at least one power switch of said second resonant converter is shifted in phase with respect to switching frequency of said at least one power switch of said first resonant converter; wherein rms ripple current (I wherein I wherein said ripple current I
