Keywords-Matrix converter; PWM with three intervals; Venturini control algorithm; Fuzzy logic control; power quality; Induction motor drives system; One of the most interesting members of the power electronic equipment is the matrix converter (MC), This converter is an attractive AC/AC direct power conversion topology. It has main advantages of adjustable speed and power quality compensation compared to AC/DC/AC conventional conversion in following, High quality in input and output current
... output current sinusoidal waveforms, zeros consumption of reactive power, and it has high a variable frequency. This paper proposes the application of a matrix converter to a induction motor drive system, where the matrix converter generates three phase pulse width modulation (PWM) voltage pulses, to obtain high waveforms sinusoidal input/output current with high performance dynamic of induction motor. Using a fuzzy logic controller (FLC) to regulate the voltage transfer ratio, which is the relationship of the output voltage to the input voltage. the objective of Venturini control algorithms is to control the amplitude of the output voltage. So, in this algorithm by adding the third harmonics of the input and output voltages, the voltage transfer ratio, can be increased up to the desired output voltage amplitude. Simulations results will be presented and interpreted.
