Abstract

Multilevel inverter is a device which is capable of producing different voltage levels. The proposed multilevel inverter has been analyzed in both symmetric and asymmetric operation modes.This paper proposes cascaded multilevel inverter using flip flop and logic gate. By using the four bit counter, the Boolean equation is formed from the switching table. The equations are given as the input to each switch of the multilevel inverter by using the logic gates. The proposed topologies can produce the outputs which are nearer to the sinusoidal wave. This proposed system is used to reduce the Total Harmonic Distortion (THD). A great perfection in voltage level number with minimum switching devices has been obtained in both symmetric and asymmetric modes. Thereafter a detailed study of losses and Peak Inverse Voltage (PIV) of the proposed multilevel inverter is given.Finally a computer simulation using Matlab/Simulink is presented and a laboratory prototype implementation verifies the results.
