Abstract:
1. An apparatus comprising: a series resonant inductor coupled to a switching network and a transformer; a series resonant capacitor coupled to the switching network and the transformer; a first parallel inductor implemented as a magnetizing inductance of the transformer; a second parallel inductor implemented as a separate inductor, wherein a first inductance of the first parallel inductor is greater than a second inductance of the second parallel inductor; and a switch connected in series with the second parallel inductor, wherein a terminal of the switch is directly connected to a terminal of the second parallel inductor, and wherein a first terminal of the second parallel inductor and the first parallel inductor are separated by a resonant element, and a second terminal of the second parallel inductor and the first parallel inductor are separated by the switch.
