—This paper proposes a CLL resonant dc–dc converter as an option for offline applications. This topology can achieve zero-voltage switching from zero load to a full load and zero-current switching for output rectifiers and makes the implementation of a secondary rectifier easy. This paper also presents a novel methodology for designing CLL resonant(More)
— The design and breadboard implementation of a constant-frequency, zero-voltage-switched, full-bridge pulsewidth modulation converter delivering a 12-V-at-1-kW output from a 350–450-Vdc input bus is described. The zero-voltage switching characteristic is maintained over a wide operating range by utilizing the transformer magnetizing inductance as an energy(More)
