Quasi-square-wave ZVS converters

Quasi-square-wave ZVS converters. A quasi-square-wave ZVS buck. Resonant transitions but transistor and diode conduction intervals are similar to PWM Tank capacitor is in parallel with all semiconductor devices, hence all semiconductors operate with ZVS

Active clamp circuits

Active clamp circuits. Can be viewed as a lossless voltage-clamp snubber that employs a current-bidirectional switch See Vinciarelli patent (1982) for use in forward converter Related to other half-bridge ZVS circuits Can be added to the transistor in any PWM converter
