Fault Tolerant Ability of A Multi Level Inverter Fed Three Phase Induction Motor for Water Pumping Application

A more suitable model of multi-level inverter with fault tolerant ability is studied and analyzed in this paper. Here, an accurate comparative evaluation can adduce evidence of the multi level inverter with the traditional cascade inverter for solar water pumping systems is conferred. The modified multilevel inverter which is proposed helps in minimizing the number of gate drivers and switch count compared to other genre of multilevel inverters. A level shifted multi carrier PWM is the technique used for the proposed system. For the meticulous analysis, the suggested five-level and the present 5-level inverters are built using MATLAB platform. And naturally the topology that has been designed accomplished well while in comparison to the conventional. In order to state the feasibility of the recommendeda simulation analysis is accomplished and varied results are presented.
