A Novel Soft Switching Converter with High Voltage Gain and Amplified Efficiency for Photovoltaic Applications

Abstract

This paper proposes a soft switching converter with high voltage gain for ac and dc photovoltaic applications. Day to day energy usage is snowballing significantly. Dc-Dc converters are the major consequence in renewable grid connected power applications because of the low voltage PV arrays. This shortcoming is overcome by using a novel soft switching dc-dc converter. This proposed concept is used to change the power efficiency by boosting voltage and also reduces the switching losses and efficiency. This problem is handled by using a high gain interleaved dc boost converter with capacitor and leakage inductor. A passive clamp network round the inductors affords the recapture of energy through leakage inductance leading to upgrading in the voltage gain and efficiency. The benefit of passive clamp network is that it condenses voltage stress on the switch. This proposed converter is designed and implemented by MATLAB/Simulation software and the results are results are validated.
