Digital models of pulse-width voltage control system with step switching of power supply frequency and automatic control of induction motor are developed and built, the recommendations on the algorithm of their control and circuit solution for the implementation of smooth start modes, nominal and frequency-step control from low-power -variable load schedule are provided.The novelty of the work lies in the substantiated sequence and conditions of control and originality of the structure of the automatic system of smooth start-up and activation of the effective mode of the asynchronous drive.The introduction of the conversion system will create an automatic system of asynchronous drive, due to which it is possible to achieve energy conservation at all levels of the electromechanical system, with minimum capital investment.
