Performance analysis of SRM drive using multi level inverter

Abstract

In Multilevel Inverters, Cascaded H bridge converters are considered to be the most preferred form of converters. But in these converters as the number of staircase levels in output voltage increases the dc source requirement also increases, thereby limiting its application. This paper tries to address the above mentioned problem by developing a Modified version of Cascaded Multilevel Converters which require reduced number of dc voltage source for increased levels in output voltage as compared to conventional cascaded converters. Due to these advantages the drawback in the implementation of conventional cascaded converters in electric Vehicles or in industrial applications is overcome by modified cascaded inverters. The output of the Cascaded H bridge converter given to SRM drive. The main draw backs of SRM are torque ripple, vibrations and acoustics of noise. By the reduced THD% using Cascaded H bridge converters, the performance of SRM drive is analyzed and simulated using MATLAB/SIMULINK environment.
