摘要：

Contactless power transfer systems require compensators to improve power factor degradation caused by significant leakage inductance in the contactless power transformer. The most commonly used compensators are LC series- and parallelresonant compensators. In this paper, we present a comparison between the characteristics of the compensators with a focus on transfer efficiency. Based on these characteristics, a compensator capable of switching between the LC parallel- and series-resonant topologies is proposed, and its changeover algorithm is explained. The proposed compensator was experimentally examined and was found to perform efficiently over a wider range of output power than conventional LC resonant compensators.
