Standalone inverters based on solar photovoltaic (SPV) systems have become increasingly popular in domestic and commercial applications. Solar photovoltaic (PV) systems are becoming more important to the world in the twenty-first century to meet the electricity demand. However, due to variations in temperature or irradiation, the output voltage of the SPV system has larger ripples and, as a result, the output power is often variable. The MPPT algorithm is implemented using an appropriate DC-DC converter to address these hassles.

The Reliability of power electronic devices has been an important issue since the early power electronic applications introduced. The power electronic converter plays a crucial role in the failures of a PV system. The unscheduled maintenance failure due to power electronics devices are 37 % of the total failure. In that 31% of the failures are due to the power semi conductor devices. In recent years, many researchers have conducted reliability assessments of power electronic devices, yet the reliability of numerous circuits used widely has not been evaluated. This project presents a...
