Contactless power transformers have considerable leakage inductance because of the presence of a large air gap between their primary and secondary coils. To eliminate the influence of leakage inductance on the performance, the contactless power transfer system employs power factor compensators. This paper reports on the performance of an LCLC compensator derived using a novel approach. The experiments confirmed that the LCLC compensator can reduce the harmonic components of the currents and improve the power factors in the system connecting to a full-bridge diode rectifier. Then, it is proved that the LCLC compensator has higher transfer efficiency than an LCL compensator.
