The inductance current is usually used for ZVS control, parameters identification, power control, etc. Acquisition of its time-domain model is the key to achieving the above objectives. This article studies the time-domain modeling method of inductance current and proposes an online inductance current modeling method for the SS-compensated WPT system. Firstly, the output voltage harmonic components of the high-frequency inverter using phase shift control and the filtering characteristics of SS topology are analyzed. Then, the principle of amplitude and phase extraction of inductance current based on orthogonal modulation and demodulation method is introduced; Finally, the difference between the simulation current and the calculation current is analyzed. The accuracy of the proposed method is verified through simulation.
