Abstract :
Magnetic resonance coupling is a widely used technique for wireless power transfer (WPT) in biomedical and consumer electronics applications. For specific applications, device size limits the overall size of the transmit and receive coils. In this work, design considerations for an asymmetrical 4-element WPT system are investigated. For either a target efficiency or a desired WPT range, the optimal coil parameters such as Q and coupling coefficient are defined and these design considerations are experimentally verified. The results can be used to design an optimal set of coils for various WPT applications.
