Abstract

Nowadays, multilevel inverter is of high importance in various applications ranging from few watts to several megawatts power levels in industries. But the failure rates of these inverters are also an area of concern. This paper proposes a generalised fault-tolerant structure of multilevel inverter. The proposed inverter delivers power to the load under faulty switch conditions. Thus, it maintains continuous power supply to the load with improved reliability. Reliability of the proposed structure is evaluated with mean time to failure (MTTF) calculations using the Markov chain method. The performance of proposed structure is validated via simulation in MATLAB/Simulink environment.
