description: The topic of the final qualifying work: Development of a methodology for calculating a power source with an intermediate high-frequency link with a DC output for electric arc plasma torches. This work is devoted to the study of a high-frequency power supply of a plasma torch with a DC output, which includes the design and calculation of all its main elements. The following tasks were solved during the design: 1. Formation of the power supply circuit, selection of source data; 2. Calculation of parameters of a high-frequency transformer; 3. Calculation and selection of IGBT transistors; 4. Calculation of LC filter and current limiting choke parameters; 5. Calculation and selection of input and output rectifier; 5. Simulation of the power supply in Matlab/Simulink. Using the available information, a power supply circuit has been created in the Matlab/Simulink software package. The principle of its operation and composition has been to obtain external characteristics, graphs and time diagrams that show that this scheme is working and ready for modeling the operability of this scheme
