چکیده
The presented paper deals with the implementation of the Switching Table Based Direct Torque Control (ST-DTC) in the matrix converter-fed induction motor drive. In order to improve the control of the matrix converter input power factor, the use of the simplified Indirect Space Vector Modulation (ISVM) was proposed. To verify the feasibility of the proposed solution, experimental results were presented.

Direct torque control (DTC) is a fast and simple torque control method for induction motor without speed sensor. Conventional AC-DC-AC converter has a large DC link capacitor and low power factor in the input power line. In the matrix converters the DC link capacitor can be reduced and the unity input power factor can be obtained. In this paper a new method for direct torque and stator flux con...
