Fuzzy Based Power Quality Enhancement Strategy for Three Phase Ac-dc Converter
نویسندگان
چکیده
The paper attempts to improve the overall power quality of an AC-DC conversion system through a fuzzy based mechanism. It extracts the reference wave for the Pulse Width Modulation (PWM) strategy, with a view to eschew the multiple frequency components of the input current, minimize its THD and arrive at nearly unity power factor. The scheme exploits the inherent advantages of a three phase ac-dc converter, relies only on the absolute values of the input phase currents and is independent of the nature of the mains phase voltages. It involves the use of a Digital Signal Processor (DSP) based prototype to articulate the simulation results and there from highlight the merits of the proposed methodology.
