PV Conversion of an Isolated Boost Resonate Converter

Abstract

Effective photovoltaic power conditioning requiresufficient power conversion and accurate maximum power pointtracking to counteract the effects of panel mismatch, shading, andgeneral variance in power output during a daily cycle. In this paper,the authors propose anboost converter withlow component count, galvanic isolation, simple control, as well ashigh efficiency across a wide input and load range. Provided is adiscussion of the converter synthesis, key operational features, converterdesign procedure, and loss analysis, as well as experimentalverification by way of a 250-W prototype with a California EnergyCommission efficiency of 96.8%.
