本文提出了负载电抗实现谐振在两个接收器的感应电能传输系统与两个共面发射器。在所提出的系统中，负载电抗的调整取决于耦合网络的阻抗，负载电阻，和源电压。此外，控制方法，以获得共线输入电流，以验证所提出的负载电抗的计算。电磁仿真结果表明，所提出的系统优于传统的单独抵消线圈的自感。此外，这项工作还表明，所提出的系统的传输效率仍然高于传统的一个，即使当接收机的错位高达50%的大小。
This paper proposes load reactances for achieving resonance in two-receiver inductive power transfer systems with two co-planar transmitters. In the proposed system, the load reactances are adjusted depending on the impedances of the coupling network, the load resistances, and the source voltages. Additionally, control method for obtaining the collinear input currents is presented to validate the calculation of the proposed load reactances. Electromagnetic simulation results illustrate that proposed system outperforms conventional one of individually canceling out the self-inductance of the coils. Moreover, this work also shows that the transmission efficiency of the proposed system is still higher than that of the conventional one even when the receivers are misaligned up to 50 percent of their size.
