Hybrid Fuzzy Logic Controller Using Photovoltaic Based Push Pull Converter and Three Phase Inverter Fed Induction Motor Drive

Abstract

In this paper solve the problem of how many number of levels necessary to increase for harmonic reduction. Thus a new push pull converter which is two switch topology can do justice by giving a high power throughout. The harmonics content of the output signals are analyzed. A sinusoidal Pulse Width Modulation (SPWM) method for a multilevel inverter that supplied an induction motor is developed. This converter has high voltage gain, in addition the input current having its current ripple amplitude halved and minimizes the oscillations at the module operation point. A hybrid Fuzzy Logic Controller (HFLC) is used as a speed control for Induction Motor. A three phase Induction motor connected to Voltage Source Inverter (VSI), which in turn runs the centrifugal pump. The whole system is controlled using Matlab/Simulink environment. The dynamic performances of an Induction Motor (IM) drive is controlled in the presence of fuzzy logic controller, which increases the overall efficiency of the system. The effectiveness of hybrid fuzzy system and energy storage management in water pumping system are demonstrated and implemented.
