Asynchronous motor drive based on self-excited current inverter with switched-off thyristors and provided with predicting relay and vector regulation of stator current

Methods for predicting relay and vector regulation of the stator current in a drive are presented based on an analysis of electromagnetic processes in an asynchronous motor drive based on a self-excited current inverter with switched-off thyristors. A system of automatic control of the drive speed using this type of regulation is developed, and electromechanical processes in the drive equipped with this system are also studied by methods of imitation modeling.
