摘要

频率调制广泛应用于感应功率传输系统,也包含在低功率充电器的Qi标准中。本文以频率调制下的S-S补偿系统为例,研究了小信号建模和简化方法。首先,建立了频率扰动下的谐振分量模型,从而有助于建立谐振槽的模型。结合逆变器和整流器的模型,推导出整个系统的六阶模型。极点零分析有助于将六阶模型简化为三阶和一阶模型。实验结果表明,该模型可以准确地预测系统在开关频率的1/2、2/5和1/10范围内的控制输出增益。这些模型有效地说明了电路参数的影响以及在精度和复杂性之间的权衡。

Small-Signal Modeling of an S-S Compensated IPT System Under Frequency Modulation
Frequency modulation is widely utilized in inductive power transfer systems and is also included in the Qi standard for low-power chargers. This brief examines small-signal modeling and simplification methods using an example of an S-S compensated system under frequency modulation. Initially, it develop models for the resonant components under frequency perturbation, which subsequently help in constructing the model of the resonant tank. By incorporating the models of the inverter and rectifier, it derives a sixth-order model for the entire system. The pole-zero analysis helps simplify this sixth-order model to a third-order and a first-order model. Experimental results show that these models can accurately predict the system’s control-to-output gain up to 1/2, 2/5, and 1/10 of the switching frequency. These models effectively illustrate the impacts of circuit parameters and the trade-offs between accuracy and complexity.
