In this project, feeding the induction motor by AC/AC converter examined. The AC/AC converters used in this study are thyristor converters and matrix converters. The load of the induction motor is centrifugal pump or air blower, which have 2-degree torque-speed curve. At first, the structure and performance of each of the two converters were examined, and then theoretically, the effect of the converters on the motor was investigated. Subsequently, in the simulation environment, the induction motor under the load is fed by each of these converters and it is shown how much and to what extent can control the motor. After seeing the results, a method has been presented to improve the condition of the thyristor converter that the THD of the line side current is improved. Eventually, in the laboratory, a thyristor AC/AC converter is made and an induction motor with a fan-type load is fed by that.
