Efficient soft-switching dc-dc converter for MPPT of a grid connected PV system

This study analysis of soft switching front end dc-dc converter for MPPT controller of a grid connected system finds the solution to achieve obtaining maximum power point from the PV module. The expression “soft switching” ensures that the operation of power electronic switches operated only at zero-voltage called zero voltage switching(ZVS) or zero-current switch (ZCS). There are many different converter circuits that are working according to this soft switching principles are mostly resonance technology. In this paper we shall see the analytical comparison and conclusion which helps to find the most efficient technique to achieve maximum power point tracking.
