A zero voltage switching (ZVS) or zero voltage transition (ZVT) bridge converter for driving a rectifier circuit. A clamp winding or inductor is placed in parallel with a resonant choke of the bridge converter. The clamp winding clamps the voltage at the resonant choke. Clamping the resonant choke in turn limits the voltage at the secondary winding of an output transformer. The output transformer is connected to the rectifier circuit. By limiting the voltage at the output transformer, the voltage at the rectifier circuit is limited as well.
