Abstract

This paper describes a Fault-Tolerant (FT) multilevel inverter (MLI) that can continue to operate even when an open switch fault (OSF) occurs in one or more power switches for PV applications. More power switches in dc-ac converters were used to achieve higher voltage quality, raising the probability of failure. This is one of the major challenges associated with the widespread use of MLI in a wide variety of industrial settings. Concurrently, the best accuracy in the output voltage can be achieved by reduced device count multilevel inverters (RDC-MLIs) at the expense of critical characteristics (such as fault-tolerant capability, charge balancing management, etc.). Reliable switching modes have been given top attention in terms of MLIs' ability to operate in fault-tolerant conditions.
