The work process of medium-frequency power supply is complicated .Its waveform is complex and can not be measured conveniently. Therefore,This paper focuses on the analysis of operating principles and control methods of medium-frequency power supply, to determine its basic structural units.A simulation model of medium-frequency power supply which is controlled by pulse width modulation (PWM) is built with the electromagnetic transient analysis software PSCAD. The simulation and analysis of the medium-frequency power supply circuit are performed on the basis of the model.The simulation waveform can reflect the working process of medium-frequency power supply accurately. So this paper will provide a reliable basis for further research of medium-frequency furnace.

Abstract Intermediate frequency induction heating is widely used because of its low energy consumption and high thermal efficiency, but the speed of traditional intermediate frequency power supply is slow and its frequency tracking accuracy is limited. In order to maintain the resonant state of the load during the working process of the induction heating power supply and realize the automatic frequency tracking control during the working process. The frequency tracking of the 40kW intermediate frequency power supply is researched, and a method of combining the resonant frequency automatic identification algorithm and the digital phase locked loop frequency tracking control method is proposed. MATLAB simulation and experiment show that the system based on this control method can save the time of searching the load resonance frequency in the initial stage of the power supply, improve the frequency tracking speed, accelerate the dynamic response speed of the system, avoid the failure of frequency lock, and play the role of fast and stable startup.
