摘要：In this paper, a new symmetrical cascaded multilevel inverter is proposed. Multilevel inverter is a device which is capable of producing different voltage levels. The proposed multilevel inverter is analyzed in symmetric mode of operation. This paper proposes a cascaded multilevel inverter by using digital and embedded controller. In digital controller, by using four bit counter; the Boolean equation is formed from the switching table. These equations are given as the input to each switch of the inverter by using logic gates. But in embedded controller coding is used to trigger the pulse. This coding is written by using switching table. The proposed topologies can produce the five level output which are nearer to the sinusoidal wave. This proposed system is used to reduce the total harmonic distortion (THD). To validate the developed technique, simulations are carried out through MATLAB/SIMULINK.
