FUZZY CONTROLLER FOR MATRIX CONVERTER SYSTEM TO IMPROVE ITS QUALITY OF OUTPUT

In this paper, Fuzzy Logic controller is developed for ac/ac Matrix Converter. Furthermore, Total Harmonic Distortion is reduced significantly. Space Vector Algorithm is a method to improve powerquality of the converter output. But its quality is limited to 86.7%.We are introduced a Cross coupled DQaxis controller to improve power quality. The Matrix Converter is an attractive topology for High voltagetransformation ratio. A Matlab / Simulink simulation analysis of the Matrix Converter system is provided. The design and implementation of fuzzy controlled Matrix Converter is described. This AC-AC system isproposed as an effective replacement for the conventional AC-DC-AC system which employs a two-steppower conversion
