摘要
为解决现有感应耦合电能传输(ICPT)系统主要利用逆变器输出方波中的基波分量进行电能传输所带来的输出调压范围不够宽、调压精度及系统效率不够高等问题,基于谐波的高频特性与能量特性,提出一种基波—谐波双通路并行ICPT系统,通过在逆变器输出之后建立基波能量通路与谐波能量通路,对逆变方波中的基波及谐波分量进行提取、利用,以拓宽系统的调压范围,同时提高了系统效率。首先,阐述了基波—谐波双通路并行ICPT系统的工作机理;接着,分析了系统关键参数对系统效率与选频特性的影响;然后,结合该系统基本思想,提出一种宽范围调压方法;最后,通过实验验证了基波—谐波双通路并行ICPT系统原理的正确性与调压方法的可行性。
In order to solve the problems of narrow output voltage regulating range,low regulating precision and efficiency in existing inductively coupled power transfer（ICPT）systems brought about mainly by using the fundamental wave of the inverter to transfer power,a new ICPT system with fundamental wave and harmonic wave two-path parallel transmission is proposed.By building the fundamental energy path and harmonic energy path after the inverter output using the high frequency and energy characteristics of the harmonic wave,the fundamental wave and harmonic wave of the inverter are extracted and used to widen the regulating range and improve the system efficiency.Firstly,this paper expounds the working mechanism of the proposed system.Secondly,the influence of the critical parameters on system efficiency and frequency selection characteristic is analyzed.Thirdly,according to the basic idea of the proposed system,a voltage regulating method with wide range is proposed.Finally,the theoretical analysis of the proposed system and the feasibility of voltage regulation method are verified by experiment.
