In tills paper, an Improved full wave mode ZVT - PWM DC-DC Converter is presented to maximize the regeneration ratio of resonant energy by only putting an additional diode in seres with auxiliary switch. The operation of auxiliary switch in a half wave mode makes possible the soft switching con야tion of all switches Furthermore, the increase of the regeneration ratio to resonant energy results in low conduction losses and minimum voltage and current stresses The operation principles of the proposed converters are analyz -00 using the PWM boost converter topology as an example Theoretically analysis and experimen -tal results venfy the validity of the boost converter topology with the proposed full wave mode ZVT-PWM converters<br/>
