  • Abstract Multi-band coil modules facilitate efficient access to distinct-band, high-power, or rapid-charging wireless power transfer (WPT) systems. It will be one of the important WPT research topics in the future. A dual-band WPT coil module is presented as an example of multi-band WPT applications in this dissertation. Different from multi-coil dual-band WPT, no unwanted cross coupling exists in this dual-band coil module because it uses only one coil for power coupling. An analytical process of the dual-band coil module design guideline is presented. By selecting appropriate coil parameters, the improvement of coil power transfer efficiency in the weakly coupling region can be obtained and the frequency splitting in the strongly coupling region can be avoided.
    When the frequency ratio between two operating frequencies is large, dual-band WPT do not function efficiently. To overcome this problem, the enhanced dual-band coil modules that adopt repeaters in the WPT system is proposed. In comparison to the conventional analysis of a single-band repeater, the circuit-based analysis for repeaters applied at various dual-band coil modules is presented. The analytical results provide a design methodology applicable to diverse types of dual-band coil modules with a repeater in the WPT system. The experimental results are consistent with the circuit-based analysis. Therefore, efficient dual-band coil modules are obtained in this dissertation and they facilitate the realization and application of multi-band WPT systems.
