Enhancement of Markov Power Converter Efficiency for Solar Generating Systems under different Environmental and Operational Conditions

Abstract

With the increasing demand to shift towards renewable energy sources, solar photovoltaic (PV) systems have been a widely recognized source for sustainable power generation. In this vein, the reliability of these systems is as important to have a long life and effectively operate reliably especially with its power converters. In this work, we explore the reliability analysis of power converters in solar PV system considering methodologies such as Markov Analysis and studying impacts to internal parameters, switching frequency; component quality evaluation. It also, presents a comparison of new multi-level inverters to the traditional cascaded multilevel inverter with respect their reliability.
