The sinusoidally modulated staircase switching technique is utilized to control level generating circuitry to produce only positive voltage across H-Bridge terminals. H-Bridge circuitry is used to generate polarities. In this technique, optimal switch count is considered for this topology. The proposed topology was analyzed in MATLAB/SIMULINK and also a mathematical analysis was done for THD calculation. In both analyses, the THD was found 0.27 for the modified topology. For experimental validation of this modified topology, a prototype was developed and tested in the laboratory. The experimental waveform for a 60W electric bulb is shown in this paper. Finally, The THD of output voltage and efficiency of the inverter were found 1.13 and 93.7 respectively using HIOKI PW3337 POWER METER. © 2022 IEEE. %R 10.1109/IEACon55029.2022.9951803 %D 2022 %L scholars17346 %J 2022 IEEE Industrial Electronics and Applications Conference, IEACon 2022 %O cited By 1; Conference of 3rd IEEE Industrial Electronics and Applications Conference, IEACon 2022 ; Conference Date: 3 October 2022 Through 4 October 2022; Conference Code:184531
