Abstract: Recent advances and development in power electronics and control technologies have made the multilevel concept practical. Much research has been done on the advanced control and modulation algorithm for increasing the level of inverter output and decreasing Total Harmonic Distortion (THD). In this paper Dual Cell three phase seven level inverter has been investigated, modeled and analyzed. Digital simulation has been performed on MATLAB Simulink platform in SimPower System blockset to verify the model and analysis. The results obtained are discussed and shown that the THD of the system is coming 3.12% for voltage and 1.96 % for current (a very low THD and under the limit given by IEEE standards).
