Simulation of Five Level Cascaded H-Bridge Multilevel Inverter with and without OTT Filter

Abstract

This paper deals with the five level cascaded H-bridge multilevel inverter using sinusoidal pulse width modulation (SPWM) technique, with and without OTT filter. The MLI converts DC input voltage into staircase AC output voltage. The distortion in AC output voltage of the inverter can be reduced using OTT filter. The total harmonic distortion of 0.62 produces from five levels MLI can be reduced to 0.10 using OTT filter. Thus, the reduced total harmonic distortion (THD) is achieved. The Matlab–Simulink is used to simulate and analyze the results.
