Abstract

This paper presents a new design strategy for S-LCC type compensation network in Inductive Power Transfer (IPT) systems. It was found that four resonant elements (three capacitors and one inductor) can compose two symmetric T type resonant tanks, which is well-known for its impedance transformation characteristic and reciprocity between voltage source and current source. A simplified analytical technique is used to calculate the voltage gain and parameters for each resonant element. Besides, the proposed tuning method for S-LCC network has negligible response to high-order harmonics, allowing wide range of output voltage regulation and easy implementation of ZVS. To verify the analysis, a prototype with 20mm gap was fabricated and tested. An overall efficiency 86% was achieved from DC 60V to DC 24V.
