摘要

宇称时间对称无线电能传输(parity-time symmetric wireless power transfer，PT-WPT)系统能够克服耦合条件变化的影响，在一定传输距离内保持恒定的输出功率和传输效率。该系统是高阶、时变且非线性的。目前，其稳定性分析方法存在计算复杂和通用性弱的不足。该文提出基于描述函数法的PT-WPT系统稳定性分析方法，探明系统的稳定性规律，揭示其选频和跳频的机理，提出通过控制逆变器输出电压占空比抑制跳频的选频策略。最后，搭建串联-串联型PT-WPT样机验证了所提稳定性分析方法、选频及跳频机理、跳频抑制策略的正确性和有效性。

Abstract

The parity-time symmetry wireless power transfer (PT-WPT) system can maintain constant output power and transmission efficiency within a certain transmission distance against the impact of variations in coupling conditions. PT-WPT systems are high-order

time-varying

and nonlinear. Currently

methods for analyzing their stability suffer from computational complexity and lack of generality. This paper proposes a method based on the Describing Function Method for analyzing the stability of PT-WPT systems

revealing their stability characteristics. The paper also uncovers the mechanisms behind frequency selection and frequency hopping

and introduces a frequency selection strategy that suppresses frequency hopping by controlling the duty cycle of the inverter’s output voltage. Finally

a Series-Series PT-WPT system was established to validate the correctness and effectiveness of the proposed stability analysis method

frequency selection

frequency hopping mechanism

and frequency hopping suppression strategy.
