Abstract
In this thesis, improved full wave mode ZVT(Zero-Voltage-Transition) PMW DC-DC Converters are presented to maximize the regeneration ratio of resonant energy by only putting an additional diode In series with the auxiliary switch. The operation of the auxiliary switch in a half wave mode makes it possible soft switching operation of all switches including the auxiliary switch whereas it is turned off with hard switching in conventional converter. The increase of the regeneration ratio to resonant energy results in low commutation losses and minimum voltage and current stresses. The operation principles of the improved ZVT PWM DC-DC Converters are theoretically analyzed using the boost converter topology as an example. Both theoretical analysis and experimental results verify the validity of the PWM boost converter topology with the improved full wave mode ZVT PWM converters.
