| Abstract: | In this study, a novel Power Factor Correction System based on Sliding Mode Fuzzy Control is presented. This structure is used as an AC/DC/AC drive system for asynchronous machine. Non-sinusoidal source current of the system is improved to a sinusoidal waveform by the novel Power Factor Correction System controlled by Sliding Mode Fuzzy Controller. Sliding mode control technique (variable structure control) is preferred because of its robustness. Additionally, fuzzy control algorithm is adapted to Sliding Mode Control for eliminating or reducing chattering problem. A DC–DC boost converter is used to provide DC-link voltage to the inverter Three-phase voltages for Space Vector Pulse Width Modulation technique are represented by a voltage space vector in α-β space using the Clarke transformation for two-level voltage source inverter. The harmonic performance of the AC/DC/AC drive system, source side and load side current waveforms, and total harmonic distortion (THD) values are given in figures. Experimental results show the significant improvement in source current with eliminated harmonics and increased power factor from 0.63 to 0.998 value. |
