An Overview of Multilevel Inverters Lifetime Assessment for Grid-Connected Solar Photovoltaic Applications

Nowadays, due to advancements in power electronic devices as well the rise consumer awareness of need protect environment on a global scale, many people are turning use solar photovoltaic (PV) technology distributed generation side. In field electronics, manufacturers develop products that have high lifespans. Power device reliability is important for maintenance and may be scheduled under information. Rather than preventing failures, can improved by predicting them. Even though some research has been conducted over past few years investigate devices, common circuits not investigated this leads big challenge researchers. review paper, an overview grid-connected multilevel inverters PV systems with motivational factors, features, assessment parameters, topologies, modulation schemes inverter, selection process specific applications presented. findings comprehensive analysis fundamental studied. To evaluate three basic inverters, calculation made using each component’s mean time before its failure. Two techniques computation approximate exact were used arrive at final result. calculate losses temperature-sensitive components such diodes switches, MATLAB Simulink employed. addition, concept oversizing arrays presented study. This proposes energy output increased increasing size array conditions poor irradiation. Finally, mission-profile-based Monte Carlo simulation-based methods flows discussed accurate lifetime prediction assessments real-time scenario, followed conclusion future work.
