Original Abstract
This chapter discusses the fault in a grid-connected photovoltaic (PV) system along with it impact on the system and the method to identify such faults. It explains the fault related to the PV panel and power electronics converter in detail. The chapter also discusses a common fault in the inverters and the most vulnerable component, i.e. power electronics switch. With advances in semiconductor technology, insulated gate bipolar transistors (IGBTs) have become the best switching devices for power electronics applications. However, because of the intermediate circuit capacitors, it is one of the most susceptible components in grid-connected PV systems. IGBTs are prone to failure due to electrical, mechanical, and thermal overloads. There are two types of IGBT failures: wearout failure and catastrophic failure. Investigation of wear defects in IGBTs is very important to ensure the reliability of power electronics converters. The chapter discusses the fault detection strategies for PV system.
