Abstract: The manuscript presents a study of an electronic technological system for induction melting of metals consisting of a transistor bridge parallel current inverter, powered by an uncontrolled rectifier and a step-down DC-DC converter. To stabilize the operating mode, two regulators are used - the inverter with frequency control and maintenance of the input current by changing the duty cycle of the DC-DC converter of hysteresis when changing the control frequency of the inverter. The model is based on the use of a switching function, and studies have been conducted simulating the changes in the load during a real technological process. The presented results are also useful from the point of view of the synthesis of optimal control and adjustment of the controller coefficients.
