Fault-Tolerant Inverters for Reliable Photovoltaic Systems.

Photovoltaic (PV) systems are increasingly adopted as a source of green energy. Due to the high economic investment that they usually involve, their reliability is becoming of concern. Recent studies have proven that faults likely to affect the inverters of PV systems in the field can dramatically reduce the energy delivered to the load. We first present a self-checking monitor to detect faults af...
