In this paper, cascaded multilevel inverter with fuzzy closed loop control is proposed. The proposed cascaded multilevel inverter needs lower number of dc voltage sources, power semiconductor switches hence the complexity and the cost of the overall system decreases. Pulses for the switches are generated by using sinusoidal pulse width modulation. Procedure to generate voltage levels is developed. Closed loop control using fuzzy logic is used to improve the RMS output voltage. Simulation results are observed for seven level inverter with fuzzy logic.
