In order to solve the problem of frequent contact rail icing in urban rail transit under low-temperature environments, a contact rail de-icing method based on medium frequency induction heating technology is proposed. A control strategy for medium frequency induction heating power supply suitable for contact rail de-icing is put forward to address the issues of low control accuracy and complex circuit of traditional induction power supply. A simulation model of the system was built using MATLAB/Simulink, and the main circuit and control strategy of the system were simulated and studied. Frequency automatic tracking and phase shifted PWM power regulation were achieved, and the correctness, feasibility, and rationality of the scheme were established.
