In this paper, a simple design for extending the range of a Wireless Power Transfer (WPT) system is presented. The design consists of a traditional Conformal Strongly Coupled Magnetic Resonance (CSCMR) system that incorporates a repeater resonator, known as the U-loop resonator. Simulated and measured results show that the proposed system with the U-loop provides larger efficiency at transfer distances beyond its original optimal efficiency, achieving a peak efficiency of greater than 70% at a distance equivalent to the diameter of the U-loop, up to distances of 480 mm. The proposed system can also maintain efficiencies greater than 60% irrespective of the angular position of the receiver (RX) around the U-loop.

扩展范围的共形强耦合磁共振系统

在本文中，提出了一种扩展无线功率传输（WPT）系统范围的简单设计。该设计由传统的共形强耦合磁共振（CSCMR）系统组成，该系统结合了称为U环谐振器的中继器谐振器。仿真和测量结果表明，所提出的带有U形环的系统在传递距离上提供了更高的效率，超出了其最初的最佳效率，在等于U形环直径的距离上，达到了高达70％的峰值效率，最高可达距离为480毫米。所提出的系统还可以保持高于60％的效率，而与U环周围的接收器（RX）的角位置无关。
