Abstract

A multilevel inverter is a power electronic device made to synthesize a desired AC voltage from several
levels of DC voltages. These types of inverters are suitable in high power application due to its lower total harmonic
distortion, switching losses and voltage stress on switches than conventional inverter. This paper presents a Symmetrical
Multilevel inverter (SMLI) topology with three phase system. In comparison to CHB topology, SMLI topology requires
less no. of isolated DC sources. The symmetrical multilevel inverter is simulated for the Phase Disposition, Phase
Opposition Disposition and Alternate Phase Opposition Disposition pulse width modulation (PWM) switching control
technique with Resistive load. The total harmonic distortion (THD) of the output Phase Voltage are observed for three
PWM control techniques. Also comparing this three PWM techniques in terms of THD. The performance of the
symmetric MLI is simulated using MATLAB/Simulink.
