Chyzhenko O. Exchange energy processes in power electronic circuits of semiconductor converters

The object of research: semiconductor converters electrical circuits. The purpose of research is to find the most general regularities of exchange energy processes in semiconductor converters power circuits; to find the part of semiconductor devices in these processes. Methods of research: a theory of differential and integral equations, theory of special functions, the theory of Fourier series, theory of generalized (singular) functions, the physical basis of electrical engineering, methods for solving non-linear (transcendental) equations. Theoretical and practical results and novelty: the theory and methodology for the analysis of energy processes in the semiconductor converters power circuits are developed; original reactive power balance equations are obtained for circuits having semiconductor devices; original controlled sources of reactive power and compensatory rectifiers for the excitation systems of asynchronous generators for autonomous power systems with high loading capacity are proposed; in Sinusoidal Voltage Controllers original way of a smooth adjustment, carried out under the load, which is based on the use of reactors with the inductance discretely adjusted by a special algorithm is worked out. Degree of introduction: introduced in the plant “Peretvorjuvach” (Zaporozhje). Sphere of use: an analysis of electromagnetic processes in semiconductor converters electrical circuits.
