Abstract :
The paper is dedicated to the problem of direct frequency converter (DFC) control in AC electric drive system. The general two-step control strategy based on the coordinate PWM is presented. The developed DFC control system provides converter output voltages and input currents parameters equal to their reference values. The control system synthesis, taking into account a distorting influence of real power switches commutation process on the DFC commutation function, is conducted. The results of experimental study of operating modes of induction motor drive, fed by the two-stage DFC, are presented
