Experimental samples of engines, which correspond to the developed electromagnetic structures, are made.The main types of frequency converters with the purpose of determination of their characteristics improvement are investigated. That would provide improvement of power indices of a regulated asynchronous electric drive. Experimental researches of control algorithms of a matrix transformer and an asynchronous machine are conducted. Product Description popup.authors popup.nrat_date 2020-04-02 Close
