In the article are examined the mathematical models of the electric drive of direct and alternating current with the universal power semiconductor converter. The functional diagram of electrical power semiconductor converter is described. Are given the oscillograms of the output voltage of power semiconductor converter, obtained with the aid of the model of converter. Are determined the static and dynamic characteristics of the electric drive of direct and alternating current with the universal power semiconductor converter, which make it possible to positively estimate fitness for work and accuracy of the systems of electric drive in the steady-state and dynamic behaviors of work. The experimental studies, carried out in the laboratory mock-up of the electric drive of direct and alternating current with the universal power semiconductor converter, testify about the sufficiently high adequacy of the developed models and confirm the practical possibility of designing of the class of universal semiconductor converters for regulating the angular velocity of the electric motors of direct and alternating current.
