用于高频感应式无线电能传输的单匝空芯线圈

The efficiency of megahertz-frequency inductive wireless power transfer designs is currently limited by the quality factor of the resonant tanks and the coils. In this article, we use two-dimensional finite-element analysis to optimize the cross section of single-turn air-core inductors for this application and demonstrate coils for wireless power at high-frequency and very-high-frequency industri...
