Abstract
This paper proposes a approach to obtain a high step-up voltage with zero voltage switching (ZVS) with an isolated type DC-DC converter. The entire setup consists of a full bridge converter which utilised proposed phase shift technique and voltage doubler on the output side. The converter operated at 20kHz switching frequency which is high enough to improve the efficiency. Ferrite core transformer is used in place of ordinary air core transformer. Which is small in size with number of turns of the transformer is reduced and the overall power density is increased. The proposed doubler circuit consists of electrolytic capacitors, which are rated at 400V. This circuit results in cost savings of more than 50% in the price of the electrolytic filter capacitors. The circuits were simulated using PSIM software for an input voltage of 200V, an output of 800V obtained. And it is validated with the low power hardware model.
