摘要:
A power converter is provided, which may include_a transformer having primary and secondary windings; a primary side switching bridge arrangement including at least two switches switcheable at a switching frequency to drive the primary winding of said transformer, said primary side switching bridge arrangement including at least one decoupling capacitor; and a secondary side rectifying and filtering stage coupled to the secondary winding of said transformer, wherein said secondary side rectifying and filtering stage includes a current doubler with at least one inductor, wherein said at least one decoupling capacitor and said at least one inductor in said current doubler comprise a resonant tank circuit having a resonant frequency range encompassing said switching frequency, whereby said converter exhibits a gain defined by the position of said switching frequency within said resonant frequency range.
