description: The topic of the master's thesis: "Modernization of the APR-404 power supply for plasma spraying technology". The purpose of the thesis is modernization of the control system and cooling system of the power supply for the plasma spraying technology and cutting. The research methods are based on the development of non-stationary mathematical models in licensed software MATLAB/Simulink and Comsol Multiphysics. The study object is the power supply APR-404. Tasks that were solved during the study: 1. Analysis electrical scheme of the research object; 2. Analysis of existing solutions in the field of three-phase thyristor power supply modernization; 3. Development of a mathematical model of the cooling system in COMSOL Multiphysics; 4. Numerical simulation of the cooling system; 5. Choosing the optimal cooling mode; 6. Development of a mathematical model of a power supply with an upgraded control system in MATLAB/Simulink; 7. Numerical simulation of the upgraded APR-404 power supply; 8. Investigation of the operating modes of the power supply. As a result of the modernization, the range of operating currents of the installation has been increased by replacing thyristors with two-position thyristor modules and the overall dimensions of the power supply have been reduced by installing thyristor modules on one heatsink. The control system was replaced, the schematic diagram of the power supply was simplified by improving the control system. As a result of the modernization, the possibilities of using the APR-404 installation have been expanded.
