Abstract

A peak output voltage with a unity modulation index is desired at the output of the multilevel inverters with boosting capability. The operation of the inverter at a lower modulation index leads to lower boosting in the fundamental component of the output voltage, and hence an underrated inverter performance is achieved. Recently, an 11-level WE-Type inverter with 1.25 boosting was proposed. It was found that the level formation was hindered due to improper capacitor voltages if the modulation index was greater than 0.94, thus rendering the boosting capability to 1.175. In this work, a modified pulse width modulation is implemented on this inverter, which will enhance its capability of maximum boosting of 1.25 by making it operational at the unity modulation index. The analysis of the work is presented and supported by simulation results in MATLAB/Simulink environment.
