Abstract

This paper proposes a highly symmetrical inductive power transfer (IPT) system based on double-sided Z-impedance compensation networks. The double-sided Z-impedance networks are designed with symmetrical configuration and could achieve load-independent CC output with zero-phase angle (ZPA) of input impedance. Compared to the conventional LCC circuit, the proposed Z-network can reduce current stresses on compensation components, which contributes to high-power applications. Meantime, compensation inductors are integrated with main coils to make the whole system compact and eliminate unwanted cross couplings. The proposed IPT system is validated by experiments and 2.3kW power could be transferred with 96.93% dc-dc efficiency across an air gap of 120mm.
