description: The subject of the graduate qualification work: "Development and research of a thyristor parallel current inverter for induction heating of steel cylindrical billets with a diameter of 15 mm before stamping bolts". Objective: 1) research and modeling of induction heating of a steel product for plastic deformation before stamping bolts; 2) development of a power source for an induction heating installation. Results: 1) an approximate calculation of the inductor-billet system was made during induction heating before plastic deformation; 2) a model of electromagnetic and thermal processes has been created in the Comsol Multiphysics program, which makes it possible to study the process of induction heating; 3) researches were carried out and diagrams of distribution of electromagnetic fields, current density and temperature were obtained; 4) a model of a power supply was created for installing induction heating as a thyristor parallel inverter in the Matlab Simulink program; 5) the graphs of the output current and voltage of the power supply were obtained.
