单电容耦合无线功率传输（SCC-WPT）技术有助于提高系统的空间自由度，以在2-D平面中提供充电/供电服务。本文提出了一种具有三板紧凑型耦合器的双接收器SCC-WPT系统，以实现自由位置充电和卓越的系统性能。上级系统性能。该系统由两个独立的接收机组成，一个接收机采用LCLC-S拓扑结构实现恒压输出，另一个接收机采用LCLC-M拓扑结构实现恒流输出，两个接收机之间互不影响。通过电路分析，建立了三板耦合器的简化等效电路，并在此基础上对耦合器的CV和CC特性进行了理论分析。通过搭建一个原型系统，对耦合器和参数进行了设计和优化，验证了该系统的有效性。实验结果表明，两种接收机分别实现了恒压输出和恒频输出.当另一个接收器被移除或移入时，每个接收器的输出特性几乎不变。接收机在发射板内的任何位置都能获得稳定的输出功率。
The single capacitance coupled wireless power transfer (SCC-WPT) technology facilitates improving the spatial freedom of the system to offer charging/supply services in 2-D planar. This article proposes a double-receiver SCC-WPT system with three-plate compact coupler to achieve free-position charging and superior system performance. The system consists of two independent receivers: one receiver adopts the LCLC-S topology to achieve constant-voltage (CV) output, while the other adopts the LCLC-M topology to achieve constant-current (CC) output and did not affect each other. By circuit analysis, a simplified equivalent circuit of the three-plate coupler is established and, on this basis, the CV and CC characteristics are theoretically analyzed. The effectiveness of the proposed system is verified by building a prototype system, where the coupler and parameters are designed and optimized. The experimental results show that the two receivers can realize CV output and CC output, respectively. The output characteristic of each receiver is almost unchanged when another receiver is removed or moved in. The receiver can obtain stable output power at any position within the transmitting plate.
