The multilevel inverters (MLIs) are capable of handling large quantities power and generating high-quality output voltages. Consequently, the size filters is reduced, circuitry simplified. As a result, they have diverse range uses in industrial sector, especially smart grids. input voltage boosting feature required to utilize MLI with renewable energy. In addition, number components attain high...

This paper introduces an effective Selective Harmonic Elimination (SHE) modulation technique in a five, seven, and nine-level cascaded H-bridge (CHB) multilevel inverter (MLI). Minimization of the harmonics device counts is basis for ongoing research area MLI. Reduced hence lower Total Distortion (THD), improve output power quality. SHE low-frequency scheme to achieve this goal. techniques are ...

A method is presented to compute the switching angles in a multilevel converter so as to produce the required fundamental voltage while at the same time not generate higher order harmonics. Using a fundamental switching scheme, previous work has shown that this is possible only for specific ranges of the modulation index. Here it is shown for a three DC source multilevel inverter that, by modif...

In this article, the UXE-Type inverter is considered for eleven-level operation. This topology exhibits a boosting capability along with reduced switches and one source. An algorithm that utilizes redundant states to control voltage-balance of auxiliary direct current (DC)-link presented. The proposed capable maintaining voltages each capacitor at Vdc/4 resulting in successful multilevel operat...
