Abstract
A ZVS-ZCS PWM SEPIC for high step-Up applications is proposed in this paper. A couple of auxiliary switches work under soft switching conditions. By using this ZVS-ZCS converter topology, zero current turn-on and zero voltage turn-off of the main switch can be achieved. In addition, the auxiliary circuit enhances the energy density of the converter because of feeding the output and it can be matched easily to other kinds of converter & snubber circuits made by capacitor. The performance of the proposed converter is verified through computer-aided simulations and experimental results. © 2012 Praise Worthy Prize S.r.l.
