Design and Validation of Fault-Tolerant Boost Inverter Topology

With the use of a high number of components in the multilevel converters, the chances of converter failure due to malfunction in components are high leading to reduced reliability and performance. In this paper, a new converter topology along with the fault-tolerant configuration which can be operated in two modes of operation has been proposed which incorporates the boosting feature as well. A detailed analysis for considering the faults in different switches for different modes of operation has been analyzed. Simulation results have been presented in this paper to show the performance and efficacy of the proposed topology.
