Mathematical Analysis for Power Loss Analysis of a Seven Level Aligned Multilevel Inverter

Abstract

Multilevel inverters are widely used in many applications due to their superior performance over conventional inverter. However, due to increasing number of switches in existed multilevel inverts, the cost, size and losses are increasing continuously and these factors are directly proportional to number of inverter level. Hence, aligned multilevel invert is developed and enhanced the analysis on power loses is presented in this paper. The number of switches are used in aligned multilevel inverter is very less compared to existing multilevel inverters. Moreover, space vector pulse width modulation technique is developed for generating pulses to inverter. The mathematical calculation of power loss analysis for 7 level aligned multilevel inverteris evaluated and presented in this paper.
