Electromagnetic suspension (EMS) type maglev trains adjust currents of suspension electromagnets through maglev choppers and then control the suspension force to keep the car body stable suspension. The suspension electromagnet current ringing generated by the maglev chopper will increase the switching loss, cause electromagnetic interference (EMI), and even affect the suspension control. Studying the suspension electromagnet current ringing’s generation mechanism is helpful to find its suppression measures. An equivalent circuit model of suspension electromagnet is proposed in view of the current ringing characteristics. Firstly, the general form of the suspension electromagnet’s impedance function is derived by the driving-point function method. Then, based on the suspension electromagnet current’s unit-step response characteristics, the simplest expression of the impedance function and the corresponding equivalent circuit model are determined. Next, the influences of different circuit parameters on current ringing characteristics are analyzed by discriminant and simulation methods. Finally, with the same suspension electromagnet, the simulation and experimental waveforms of the current ringing are compared. The results show that for the specified parameters, the current ripple amplitude, ringing peak value, and ringing frequency of the suspension electromagnet obtained from the experiment are 9.7%, 20%, and 11% lower than the simulation results, respectively. In addition, the simulated current ringing attenuation time is about 1 μs, which is close to the experimental results. The simulation and experimental results of the suspension electromagnet current ringing are in good agreement in terms of the amplitude, frequency, and attenuation characteristics, validating the proposed circuit model.
