A Zero Voltage Transition DC-DC Boost Converter For PV Energy System

Abstract

The basic propose of step-up converter is implemented by using zero voltage transitions with soft switching techniques to realize the maximum output of  the PV system by using MPPT theorem. The basic ZVT converter is implemented using zero voltage transformations where as the auxiliary circuit is implemented using zero current transformations . The efficiency of hard switching converter is little, it is improved and losses are reduced by using soft switching techniques. Perturb and observe algorithm has been applied to maximise the output of MPPT.
