Abstract
A method comprises providing a resonant converter comprising a switching network comprising a plurality of switches, a resonant tank coupled between the switching network and a transformer, wherein the resonant tank comprises a series resonant inductor coupled to a switching network and the transformer and a series resonant capacitor coupled to the switching network and the transformer and a driver having an adjustable bias voltage and in response to a startup process of the resonant converter, configuring the switching network to operate a switching frequency higher than a resonant frequency of the resonant tank.
