Abstract
In this study self control of synchronous motor fed by matrix converter was examined by developing a Matlab/simulink model. Self control of synchronous motor was performed by fixing frequency of stator voltage to rotor speed. Thus, the probable danger of asynchronism of the motor during transient operation in open loop control is removed. In the developed model, simplified Venturini modulation algorithm was used. This algorithm provides unity fundamental displacement factor at the input regardless of the load displacement factor. With the proposed model it is possible to operate at four-quadrant without producing high value harmonics in a wide range of speed.
