Fault detection and diagnosis in a PV grid-connected T-type three level inverter

In grid-connected photovoltaic systems (PV) the inverter is a fundamental component. In fact, a fault in a switch of this power converter could result in an important system malfunction. Thus, fault detection and diagnosis of this fault type is fundamental to overcome this problem. This paper proposes a fault detection diagnosis for the T-type three level inverter. This inverter presents characteristics such as output voltage multilevel and good...
