N2 - This paper proposes a WPT system based on interleaved boost converter (IBC). To keep the output voltage constant when the input voltage fluctuates, the closed-loop control between the primary and secondary is implemented by adjusting the duty cycle of the IBC. The currents and loss in the primary side are reduced because the DC bus voltage of the primary side is boosted by using the IBC. The step-up characteristic of the IBC and the output characteristic of the S/S compensation topology are analyzed. A 200-W prototype was built to verify the theoretical analysis. When the power transfer distance is 50 mm, the system efficiency is as high as 90.1%. When the input voltage increases from 40 to 70 V, the system output voltage is stabilized at 100 V.
