Abstract In the Inductive Power Transfer (IPT) system, the dynamic power supply method of the subsection guide rail in parallel with the single inverter power supply and multi primary LCL coils. Butit causes the following problemwith this method, when the electric vehicle is coupled with the first LCLprimary coil, the other parallel LCL primary coils are energized, and the current of the primary coil is large, which brings IPT system power loss and large electromagnetic interference. To solve this problem, a LC network which contains the AC switch is proposed in this paper. The system’s power loss and the electromagnetic interferenceare reducedby adjusting the AC switch, regulating the current of the primary coil. Finally, the IPT experiment system is conducted to simulate the charging process of electric vehicle. The experimental results show that the proposed method effectively regulate the current of the primary coil.
