description: In the course of this work, dedicated to a transformerless source, its model with a direct current output will be developed, based on modern semiconductor devices and modern options for controlling them. When developing the source, the following tasks were solved: 1. Modern power supplies for DC plasmatrons have been studied; 2. An indicative block diagram has been developed; 3. A rectification circuit for the source has been selected; 3. IGBT transistors are calculated and selected; 4. The parameters of the LC filter and current-limiting choke are calculated; 5. A power supply model was built in MATLAB Simulink and its characteristics were taken. Based on the results of operation and modeling of the power supply in the MATLAB Simulink environment, its control characteristics and timing diagrams were obtained, which prove the operability of such a power supply for DC plasmatrons.
