High step up converters with EMI filters for Renewable Energy Resources

Abstract

This paper presents realization of high step up converters for Renewable Energy Resources (RES). The classical boost converter reveals the performance of circuit in all extreme duty ratios. The active and passive filter circuits enhancing boosting capacity of the converter. The transformer less and continuous conduction mode operation of the circuits provides low electromagnetic interference (EMI). The zero voltage and zero current switching operation provide better efficiency and reliability of the converters. High step up converters utilized for non-conventional energy resources, smart grid and battery management system in hybrid electrical vehicle systems. The circuits are simulated with PSpice 9.2 environment for various load levels and applications.
