Abstract

In wireless charging for consumer electronics, enhancing misalignment tolerance ability can improve user experience. To achieve this goal, this paper proposes a novel dual-frequency hybrid wireless charging system, which combines the series-series (S-S) and double-sided inductor capacitor capacitor (LCC-LCC) topologies at two different frequencies. The S-S and LCC-LCC topologies have opposite trends against misalignment and combining them can help achieve misalignment-tolerance characteristics. The S and LCC compensations are paralleled at the primary side and integrated at the secondary side. Thus, there are two transmitting coils, which are stacked for cross-coupling elimination, and only one receiving coil to reduce the size and weight of consumer electronics. The mathematical models are built and the misalignment tolerance mechanism is analyzed. The magnetic coupler and the design flow chart are presented. Finally, an experimental prototype is established to verify the feasibility of the proposed system. Both the misalignment-tolerance performance and the constant-current (CC) output are tested. The experimental results are well aligned with calculated ones, indicating that the proposed scheme has good misalignment tolerance performance and CC output, which is suitable for mobile desktop charging.

一种用于移动桌面充电的抗偏移集成接收器双频混合无线充电系统

在消费类电子产品无线充电中，提高容差能力可以改善用户体验。为了实现这一目标，本文提出了一种新的双频混合无线充电系统，该系统结合了两种不同频率的串联（S-S）和双面电感电容（lc - lcc）拓扑结构。S-S和LCC-LCC拓扑具有相反的抗错位趋势，将它们结合起来可以帮助实现对错位的容忍特性。S和LCC补偿在一次侧并联，在二次侧集成。因此，有两个发射线圈，堆叠以消除交叉耦合，只有一个接收线圈，以减少消费电子产品的尺寸和重量。建立了数学模型，分析了误差容差机理。给出了磁力耦合器的设计流程图。最后，建立了实验样机，验证了所提系统的可行性。测试了容差性能和恒流输出。实验结果与计算结果吻合良好，表明该方案具有良好的容差性能和CC输出，适用于移动桌面充电。
