Abstract

This study develops a new multifunctional power converter for grid-connected single-phase residential photovoltaic (PV) applications. In order to make the PV power generation system multifunctional and expandable, the backstage power circuit is composed of a step-up (boost) converter and two capacitor clamped half bridge pulse width modulation (PWM) converters for mains and critical loads respectively. The PV power system output waveforms have very little harmonics and the efficiency is also high. Experimental results are given to verify the validity and reliability of the converters for the high-performance and multifunctional grid-connected residential PV power generation system.
