Automatic Asynchronous Drive Efficiency Control with Soft-Starter Function

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