【摘要】：感應耦合無線電能傳輸(ICPT)基于電磁感應原理,目前采用電路模型的分析方法,由于該方法無法深入了解ICPT系統(tǒng)能量傳輸?shù)倪^程,所以提出了一種ICPT系統(tǒng)的能量法建模方法,建立了串聯(lián)—串聯(lián)(SS)、串聯(lián)—并聯(lián)(SP)、并聯(lián)—串聯(lián)(PS)和并聯(lián)—并聯(lián)(PP)型4種ICPT系統(tǒng)的能量法模型,分析了能量法模型與耦合模型的相互關(guān)系,研究了它們的等效性及數(shù)學意義上的等效條件,并通過MATLAB仿真研究,證明了理論分析的正確性。此外,目前ICPT系統(tǒng)與磁耦合諧振式無線電能傳輸(MCRWPT)系統(tǒng)原理相混淆,因而基于能量法模型分析了ICPT系統(tǒng)與MCRWPT系統(tǒng)在原理上的區(qū)別,得出只有在諧振、弱耦合、高品質(zhì)因數(shù)的物理條件下,SS型ICPT系統(tǒng)才與MCRWPT系統(tǒng)等效,由此闡明了ICPT系統(tǒng)與MCRWPT系統(tǒng)原理上的差異性,為進一步精確設計和優(yōu)化ICPT系統(tǒng)與MCRWPT系統(tǒng)設計提供了模型基礎。
[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.
