Makarov V. Reserve AC voltage source for the important users

Voltage inverter and semiconductor DC voltage convertors, structure of reserve AC voltage source, electromagnetic compatibility with electrical power source and load; the development of theory of reserve AC voltage sources with high dynamic characteristics and improved electromagnetic compatibility with the power supplies and load, used for the important users; theory of energy converters, method of analysis and synthesis electrical circuitry, Euler method; Fourier and Maclaurin series, recurrence equations, Z - transformations; the structure of reserve source, methods and algorithms of converter control were developed for the improvement of electromagnetic compatibility with the mains and load is proposed. Theoretical fundamentals of determination of parameters of output LC-filters of the voltage-source inverter were developed. Methodology of determination of PWM frequency and switching points of voltage-source inverter was proposed. The modified structure of control system of the DC voltage converter is proposed. Computer model was developed which allows to study electromagnetic processes in the "converter - load" system. Laboratory model of reserve AC voltage source was developed; the methods of modeling; development of theory of LC-filter characterization for autonomous voltage inverters, which working on nonlinear load, methodic of determinations pulse-weight frequency modulations and discovery commutations point in the voltage inverter are proposed; the control algorithm and system structure are improve of DC voltage converter are proposed; the state-run enterprise "Shevchenko Kharkov instrument making plant", in the educations process of industrial and biomedical electronics department National technical university "Kharkov polytechnic institute"; electrotechnical.
