description: Topic of the final work: "Contact-semiconductor circuit breaker, 400 V, 16 A".Â In this work, transformers with ferrite, steel, and permalloy cores are modeled for nominal parameters of 400 V, 16 A using the control of back-to-back thyristors.Tasks solved in the course of the work:Â Â A model of thyristor control transformers, implemented in the Comsol Multiphysics software package, has been developed.Â A magnetic system of control transformers has been selected and developed.Â The dynamic characteristics of magnetic systems have been studied.Â The overload characteristics of thyristors are calculated.Â The thermal regimes of control transformers are investigated.Â The thyristor control characteristics have been studied.Â Pictures of magnetic fields of control transformers are obtained. A drawing of a perspective switch has been made.Â The magnetic characteristics of the selected materials have been studied.Â Oscillograms of currents and voltages of the power part of the circuit were obtained, indicating the correct operation of the computer model.Â Oscillograms of currents and voltages of the control system were obtained, indicating the ability to turn on the thyristor from the control signal.Â Based on the results of calculations, the efficiency of transformers with different cores for a contact-semiconductor circuit breaker 400 V, 16 A was revealed.
