摘要

感应耦合无线电能传输(ICPT)基于电磁感应原理

目前采用电路模型的分析方法

由于该方法无法深入了解ICPT系统能量传输的过程

所以提出了一种ICPT系统的能量法建模方法

建立了串联—串联(SS)、串联—并联(SP)、并联—串联(PS)和并联—并联(PP)型4种ICPT系统的能量法模型

分析了能量法模型与耦合模型的相互关系

研究了它们的等效性及数学意义上的等效条件

并通过MATLAB仿真研究

证明了理论分析的正确性。此外

目前ICPT系统与磁耦合谐振式无线电能传输(MCRWPT)系统原理相混淆

因而基于能量法模型分析了ICPT系统与MCRWPT系统在原理上的区别

得出只有在谐振、弱耦合、高品质因数的物理条件下

SS型ICPT系统才与MCRWPT系统等效

由此阐明了ICPT系统与MCRWPT系统原理上的差异性

为进一步精确设计和优化ICPT系统与MCRWPT系统设计提供了模型基础。

Abstract

Inductively coupled power transfer(ICPT)is based on the principle of electromagnetic induction and is currently adopted using the theory of the circuit model. Because of the defect that this method is unable to help understand the energy transfer process of ICPT system

an energy modeling method of ICPT system is proposed. The energy models of four kinds of ICPT systems are created

including series-series

series-parallel

parallel-series and parallel-parallel topologies. The relationship between energy model and coupling mode is discussed

their equivalence and equivalent conditions of mathematical meaning are studied

and simulation results by MATLAB have verified the theoretical implications. Furthermore

in view of the phenomenon

the principle of ICPT and that of magnetic coupling resonant wireless power transfer(MCRWPT)are confusing

the difference in the principle of ICPT and MCRWPT are enunciated

which is based on the energy mode. It is concluded that ICPT system is equivalent to MCRWPT system of SS topology only when it meets the resonant condition

weak coupling and the coils with high quality factor

thus clarifying the differences in the principle of ICPT system and MCRWPT system

which can provide references for further design and optimization of ICPT system and MCRWPT system. This work is supported by National Natural Science Foundation of China(No. 51437005).
