— a few papers have been interested by the fixed switching frequency direct torque control fed by direct matrix converters, where we can find just the use of direct torque controlled space vector modulated method. In this present paper, we present an improved method used for a fixed switching frequency direct torque control (DTC) using a direct matrix(More)
– In this paper, a new fuzzy space vector modulation direct torque control strategy for induction machine based on indirect matrix converter is proposed. In the rectifier stage a space vector modulation strategy is employed. In the inverter stage two fuzzy logic regulators used to replace the classical PI regulators in PWM direct torque control method. In(More)
– This paper proposes a modified fuzzy direct torque control scheme of induction motor fed by matrix converter to reduce the electromagnetic torque ripple which is one of the most important drawbacks of direct torque control. This DTC scheme based fuzzy logic regulation of the virtual DC voltage in the virtual rectifier stage output. The proposed enhanced(More)
