When feeding a constant-resistance or constant-voltage type load, inductive wireless power transfer link (IWPTL) operating as current source is typically desired. Moreover, in case coupling coefficient between transmitter and receiver is constant, load-independent current output (LICO) characteristics are beneficial, allowing the system to operate without feedback. Moreover, near zero phase angle (ZPA) operation is also valuable, allowing to minimize volt-ampere rating of the transmitting-side inverter. A new LC/S compensated IWPTL topology, capable of simultaneously achieving LICO and ZPA, was recently revealed in the literature. The proposed compensation network consists of one inductor and two capacitors. This paper generalizes the LC/S compensated IWPTL topology by first deriving the compensating elements set based on a novel loosely-coupled transformer (LCT) equivalent circuit and then enlightening that for certain values of primary compensation inductor, secondary compensation capacitor should either be omitted or replaced by an inductor in order to preserve LICO and ZPA. Thus, an LC/S compensated IWPTL may actually operate in three different regions, each calling for specific sub-type of LC/S compensation. Design guidelines for compensation parameters selection are provided in this paper, allowing to achieve virtually any value of load-independent current output for a given LCT coils pair. Moreover, expressions for calculating normalized component stresses are obtained for all three regions of operation, taking into account nonlinear nature of transmitting-side inverter and receiving-side rectifier, as opposed to typical phasor-domain based approach, which ignores higher-order harmonics. Analytical results based on obtained expressions are well-supported by their real-time-domain counterparts.

当馈入恒定电阻或恒定电压型负载时，通常需要用作电流源的感应无线功率传输链路（IWPTL）。此外，在发射机和接收机之间的耦合系数恒定的情况下，与负载无关的电流输出（LICO）特性是有益的，从而使系统无需反馈即可运行。此外，接近零相位角（ZPA）的操作也很有价值，可以使发送侧逆变器的伏安额定值最小。最近在文献中揭示了一种新的LC / S补偿IWPTL拓扑结构，它能够同时实现LICO和ZPA。拟议的补偿网络由一个电感器和两个电容器组成。本文概括了LC/ S补偿的IWPTL拓扑，方法是首先基于新颖的松耦合变压器（LCT）等效电路推导补偿元件组，然后得出启发，对于某些初级补偿电感器的值，次级补偿电容器应省去或用一个电感代替。为了保留LICO和ZPA。因此，LC/ S补偿的IWPTL实际上可以在三个不同的区域中工作，每个区域都需要LC / S补偿的特定子类型。本文提供了用于选择补偿参数的设计指南，从而可以为给定的LCT线圈对实现几乎任何与负载无关的电流输出值。此外，考虑到发射侧逆变器和接收侧整流器的非线性特性，与典型的基于相量域的方法（后者忽略了高次谐波）相反，获得了用于计算所有三个工作区域的归一化分量应力的表达式。基于获得的表达式的分析结果得到其实时域对应物的良好支持。
