Comparing of Switching Frequency on Vector Controlled Asynchronous Motor Yılmaz Korkmaz1, Fatih Korkmaz2, Ismail Topaloglu2 and Hayati Mamur2 1Gazi University, Turkey 2Cankırı Karatekin University, Turkey ABSTRACT Nowadays, asynchronous motors have wide range use in many industrial applications. Field oriented control (FOC) and direct torque control (DTC) are commonly used methods in high performance vector control for asynchronous motors. Therefore, it is very important to identify clearly advantages and disadvantages of both systems in the selection of appropriate control methods for many industrial applications. This paper aims to present a new and different perspective regarding the comparison of the switching behaviours on the FOC and the DTC drivers. For this purpose, the experimental studies have been carried out to compare the inverter switching frequencies and torque responses of the asynchronous motor in the FOC and the DTC systems under different working conditions.
