【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 radio energy transmission (ICPT) is based on the principle of electromagnetic induction. At present, the analysis method of circuit model is adopted. Because this method can not deeply understand the process of energy transmission in ICPT system, a modeling method of energy method for ICPT system is proposed. The energy method models of four kinds of ICPT systems, series-series (SS), series-parallel (SP), shunt (PS) and parallel-parallel (PP), are established, and the relationship between the energy method model and the coupling model is analyzed. Their equivalence and mathematical equivalent conditions are studied, and the correctness of the theoretical analysis is proved by MATLAB simulation. In addition, the principle of ICPT system is confused with that of magnetically coupled resonant radio transmission (MCRWPT) system, so the difference between ICPT system and MCRWPT system in principle is analyzed based on the model of energy method. Under the physical condition of high quality factor, the SS type ICPT system is equivalent to the MCRWPT system. The difference between the ICPT system and the MCRWPT system in principle is expounded, which provides the model foundation for the further accurate design and optimization of the ICPT system and the MCRWPT system design.
