Investigation in Inherent Robustness Control of Diode Clamped Three Level Inverter

This paper investigates an inherent robustness control in a diode clamp multi-level inverter, because of it has numbers of power switch. This proposed control scheme acts as fault tolerance control of power switching devices in such inverter. It can hold the operation of inverter in normal condition in the event of switch failure in the circuit. MATLAB/Simulink utilized in this research to simulate and study the operation of diode clamped three level inverter in order to control such inverter in both normal and abnormal operating conditions of any power switch failure in the circuit. Simulation results show that a proposed strategy has a good ability to operate the 3 phase diode clamped three level inverter in order to ongoing through any failure conditions of power switches in such inverter circuit.
