Different compensation topologies of the inductively coupled power transfer (ICPT) system is compared in this paper; and topology selection evolved in the design procedure is investigated. Two types of compensation topologies—single-resonant compensation and multi- resonant compensation are discussed, respectively. To minimize the VA rating of switches and to optimize the parameter design, the concept of power factor in resonant converter is introduced. Voltage and current gain are obtained in each case when the turns ratio is assumed to be 1. Compared to other single compensation topologies, series compensation on primary side is more effective to nullify the leakage inductance. And compensation on both primary and secondary sides will obtain a much higher power factor than compensation on only one side. Characteristic curves vs. variation of different parameters are compared and analyzed, which is helpful in the circuit design. One of the discussed topologies is constructed as an example to verify the analysis and to demonstrate the performance of a practical system.
