Now a day’s multilevel inverters (MLI) are emerging in ac drive oriented applications. MLI topological structure that allows output voltage is to be integrated from isolated voltage sources. Various MLI topologies have been developed. The operation of the MLI is used to make a output ac voltage from variation in the dc source. This paper presents the detailed experimental study and effect of Proportional Integral controller (PI) and Fuzzy Logic Controller (FLC) for closed loop speed control of the 1-phase asymmetric cascade H Bridge (CHB) MLI fed induction motor drives. The FLC design and rule based implementation procedures are clarified. The FPGA based simulation and experimental results are tested and discussed.
