Unified Coil and Compensation Network Design for Improving Wireless Power Transfer Efficiency Over Wide Output Load Variation Ranges

It is shown that the compensation network and coil design collectively affect wireless power transfer (WPT) efficiency. Based on this fact, a novel design approach of WPT systems is proposed. Unlike the majority of existing designs that aim at enhancing power transfer efficiency (PTE) at one rated operating point, the proposed design enhances the overall system PTE. This feature is essential for v...
