Abstract

This paper refer to about the control of the induction motor drive with the Quasi-Z Source inverter and the fuzzy logic controller, for the industrial application. The quasi-z source inverter (qzs-I), provides more advantages over the conventional inverter. It provides a balanced dc-link voltage and voltage boost ability, saves one-third modules, etc. However, the Quasi-Z source inverter still cannot overcome the recurrent & stochastic fluctuation. The obtained AC voltage must be pure sinusoidal. But it can’t be obtained due to the presence of increased harmonic content in the existing system. In the proposed module, with the combination of Quasi-Z Source inverter and the Fuzzy Logic controller, controls the speed & torque characteristics through ATMEGA microcontroller 328. The impedance network used here, act as the filter and completely eliminates the harmonic content for the flexible operation of the drive.
