PV inverters convert DC voltages generated by photovoltaic modules to AC voltages, and can be feed to commercial public distribution networks, or used in off-grid system. PV inverter is the core component of photovoltaic power generation systems. Inverters, as the most electronic and electrical components used in photovoltaic power station, have relatively poor reliability and easy to failure. Increasing the reliability of the inverter can significantly improve the reliability of the whole power station, resulting in a significant increase in the average annual electricity generation of photovoltaic power stations
