The commonly used frequency domain method cannot accurately obtain the leakage and mutual inductance of the low-frequency and low-power repulsive double coils. Therefore, it is our top priority to accurately identify the leakage and mutual inductance of the repulsive double coils. In this paper, the leakage inductance of the static and dynamic coils, the mutual inductance of the coils are obtained by the method of adding a step voltage to the repulsive double coils. The simulation is based on

By fitting the simulated current waveform of the static and dynamic coils with the experimental current waveform, it can be confirmed that the parameter identification is accurate.
