Performance Examination of SEPIC Based Hybrid Cascaded Single-Phase Multilevel Inverter

Abstract

In the present scenario, reduced part count(RPC) multilevel inverters are become popular compared to traditional multilevel inverters(MLIs). This is mainly due to reduced size and cost and alleviates the issues of more passive components, flying capacitor voltage balancing issues and the requirement of complex switching schemes. Also, the RPC is getting attraction for various industrial and transportation applications. Therefore, in this paper, a novel 17 level inverter is proposed by cascading MLIs with the reduced part count. The complete operation, switching schemes and output are presented to evolve the performance under steady-state conditions using MATLAB software.
