摘要

感应功率传输系统的小信号建模已成为感应功率传输系统研究的热点。许多小信号模型已被提出并用于控制器的设计。此外，LCC-LCC补偿也广泛应用于IPT系统中。然而，逆变器和整流器的相移小信号模型尚未计算。本文基于扩展描述函数法和五级模型，建立了逆变器和整流器对输出电压相移的小信号模型。根据小信号模型，推导了传递函数。同时，本文还推导了双面LCC补偿IPT系统中存在相移的小信号模型。仿真结果验证了该模型的有效性。

Small-signal Model of LCC Compensated IPT System with Phase Shift Modulation

The small-signal modeling of the inductive power transfer (IPT) has become attractive nowadays in the research of IPT systems. Many small-signal models have been raised and used in the design of controllers. Moreover, the LCC-LCC compensation is also widely used in the IPT system. However, the small-signal model of phase shift in the inverter and the rectifier has not been calculated. Based on the extended describing function method and a fifth-grade model, the small-signal model of phase shift in the inverter and the rectifier to the output voltage is constructed in this paper. According to the small-signal model, the transfer function is also derived. Meanwhile, this paper also derives the small-signal model with the phase shift in the double-sided LCC compensated IPT system. The simulation results are illustrated to prove the effectiveness of the model.
