同时为多个负载供电的能力已经成为感应功率传输（IPT）系统在更多应用中的新特征，例如在模块化多电平变换器中为栅极驱动器供电。多米诺式IPT系统作为一种实用的结构形式，不仅可以实现更远距离的电能传输，而且可以实现与负载无关的输出。本文回顾了现有的多负载IPT系统，旨在提供一种方法来系统地构建合适的多米诺骨牌型IPT拓扑结构与多个负载无关的恒流（CC）或恒压（CV）输出。三是创新贡献。首先，总结了三种谐振电路来实现补偿网络，包括串联-串联、T型和串联型拓扑。第二，九CC和九CV拓扑结构的建议，分析，并评估为各种应用的候选人。确定了最佳CC和CV拓扑结构，并相应地提供了集成磁耦合器设计。第三，功率传输能力进行了研究，考虑到无源元件的寄生电阻。分析了负载电流/电压的衰减规律以及系统效率与负载电阻、耦合系数k、品质因数Q、负载个数N的关系，为设计具有高系统效率的负载无关多米诺系统提供了指导。通过一个单输入四输出的多米诺骨牌型IPT系统验证了该设计方法的有效性。实验结果与分析结果一致，当k = 0.193，Q = 320，N = 4时，效率可达89.79%。
The ability to concurrently power multiple loads has been a new feature for the inductive power transfer (IPT) system in more applications, such as the gate driver powering in the modular multilevel converter. As one of the applicable configurations, the domino-type IPT system cannot only transfer power over a longer distance but also achieves load-independent outputs. This article reviews the existing multiple-load IPT systems and aims to provide a methodology to systematically construct suitable domino-type IPT topologies with multiple load-independent constant-current (CC) or constant-voltage (CV) outputs. There are three innovative contributions. First, three kinds of resonant circuits are summarized to achieve the compensation network, including the series–series, T-type, and Π-type topologies. Second, nine CC and nine CV topologies are proposed, analyzed, and evaluated as candidates for various applications. The optimal CC and CV topologies are identified, and the integrated magnetic coupler designs are provided accordingly. Third, the power transfer capability is investigated, considering the parasitic resistances of passive components. The attenuation of load currents/voltages and the system efficiency relationship with load resistance, coupling coefficient k, quality factor Q, and load number N are analyzed, providing the guideline to design the load-independent domino system with high system efficiency. A single-input-four-output domino-type IPT system is implemented to validate the effectiveness of the proposed design methodology. Experimental results have shown consistency with the analysis results, and the efficiency can reach 89.79% when k = 0.193, Q = 320, and N = 4.
