V.N. Voyekov, V.N. Meshcheryakov

Abstract


Vector control systems of an AC electric drives are an object of this research papers. Development of the control system caused by requirements for improvement quality of stator voltage. Vector control system  of an AC electric drives (asynchronous, synchronous, permanent magnets synchronous motor based on frequency converter with a relay voltage regulator are considered. The given system are control instantaneous stator voltage value in preset range ensures a near-sinusoidal output voltage curve form. The mathematical description and functional charts of controlling the offered system are presented. The advantages of an offered system over the existing control system are presented.
