The purpose of the work at the first stage - the study of structures, modes of operation and characteristics of converters in power supply systems of own needs of thermal power plants; development of mathematical models of semiconductor converters for chargers and boost chargers and devices for stabilization of operational direct current in power supply systems of own needs of thermal power plants. Research methods - the general theory of electric circuits, analytical and numerical methods of research of processes in electric circuits of converters, digital modeling with use of analytical methods and simulation modeling were used in the work. As a result of research the mathematical models of DC converters for calculation of processes in stationary and transient modes are developed. For the first time, with the help of the developed models, the analytical and graphical dependences of the limit parameters of the converters that provide a given mode of operation – discontinuous or continuous current of the storage choke are determined. The obtained dependences make it possible to compare the properties of converters and select their effective parameters in stationary and transient modes of operation when used in power supply of the operational DC circuits of thermal power plants.
