Abstract

This paper presents multilevel H bridge inverter modeling with different switches as IGBT, MOSFET, power BJT and combination of IGBT MOSFET, MOSFET BJT and BJT IGBT. All results are compared and listed in the table. Ninth level inverter is taken to test improvement of THD and hence performance with hybrid switches. Finally, the percentage of THD is reduced with PI controller along with Fuzzy logic controller. Obtained results are taken from MATLAB/SIMULINK.
