Abstract: This paper presents symmetrical and asymmetrical cascaded multilevel inverter approach for high power output applications. It is based on the cascade connection of the H-bridge inverter cells. Comparison of symmetrical and asymmetrical current source multi level inverter is shown using 2 H-bridge inverter cells with cascade connection. Now ever by the supplies which are in GP with different ratios like 2,3,etc. Structural and operational characteristics are discussed and their inherent advantages are shown. Simulation using Matlab Simulink is done to verify the performance. Simulation and results for this proposed scheme are presented in this paper.
