Design and Implementation of PV inverter based on novel soft switching current Fed half Bridge front end converter

Abstract

newline quotMulti-port dc-dc isolated converter has emerged recently as very important in the case of PV based storage and distribution application. A new front end converter is introduced for efficient PV generation and Common solid state transformer to improve the converter op-erating speed. Half bridge non-isolated dc-dc converter introduced for battery storage and Controller is implemented based on BESS (battery energy storage system) for high power grid distribution proposed in secondary of transformer. Front end converter (FEC) plays a major role and its switching operation is per-formed by MPPT based pulse genera-tions.Theoverall converter performance is verified through MATLAB (Simulink). newlineRecent days the growth in peak demand for the increasing of distributed and deregulated energy systems require an optimized grid control unit. The advances in computing and communication technologies forming the traditional power network into a smart grid, capable of real-time remote monitoring and control. Mart is particularly well- suited for renewable energy sources; power is utilized, depending upon the availability of natural resources. Three port converters for interfacing multi power sources and storage devices are widely used in years. Instead of using individual power electronic converters for each of the energy sources, multiport converters have the ad- vantages including less components, lower cost, more com-pact size, and better dynamic performance. In the electric vehicle application, the regenerative energy occurs during acceleration or startup for the port connected to the energy storage to allow frictional power flow. newlinequot newline
