【摘要】：感應(yīng)式非接觸電能傳輸(ICPT)是一種新型的電能傳輸技術(shù)，由于ICPT不需要導(dǎo)體的接觸，因此在水下、易燃易爆、無塵車間等特殊場合有廣泛應(yīng)用。ICPT具有方便安全的特點，在交通運(yùn)輸和電子產(chǎn)品領(lǐng)域也有廣泛的應(yīng)用。 本文以多負(fù)載滑動式ICPT系統(tǒng)為研究對象，對ICPT系統(tǒng)的主要技術(shù)進(jìn)行了研究，主要包括松耦合變壓器的建模、補(bǔ)償電路的分析與設(shè)計、閉環(huán)控制系統(tǒng)的設(shè)計。 本文對松耦合變壓器(LCT)進(jìn)行分析，建立了松耦合變壓器的漏感模型和互感模型，并分析了兩者之間的關(guān)系。建立了考慮損耗時松耦合變壓器的模型，利用互阻抗的概念簡化了松耦合變壓器的互感模型。互阻抗簡化了松耦合變壓器的原副邊轉(zhuǎn)化關(guān)系和損耗分析，，從互感模型可以看出，設(shè)計補(bǔ)償電路時補(bǔ)償元件要與原副邊的自感進(jìn)行匹配。 本文對ICPT系統(tǒng)的補(bǔ)償電路進(jìn)行了研究。首先分析了電容補(bǔ)償電路的設(shè)計方法，對四種電容補(bǔ)償電路的設(shè)計方法和應(yīng)用場合進(jìn)行了總結(jié)，總結(jié)了設(shè)計補(bǔ)償電路的基本原則和步驟。然后分析了LCL電路的特點，分析了LCL補(bǔ)償電路參數(shù)與傳輸功率的關(guān)系，給出了LCL補(bǔ)償電路在ICPT系統(tǒng)中的設(shè)計方法，分析了副邊LCL補(bǔ)償和串聯(lián)補(bǔ)償?shù)膮^(qū)別。最后對LCL補(bǔ)償?shù)腎CPT系統(tǒng)的原邊等效電路進(jìn)行了分析，給出了原邊品質(zhì)因數(shù)與傳輸功率之間的關(guān)系，并推導(dǎo)了LCL補(bǔ)償電路的傳遞函數(shù)。 本文利用Simulink對多負(fù)載滑動式ICPT系統(tǒng)進(jìn)行閉環(huán)仿真。通過仿真分析松耦合變壓器的效率和移相全橋變換器的開關(guān)模態(tài)，分析了軟開關(guān)實現(xiàn)的條件；通過仿真分析設(shè)計閉環(huán)控制參數(shù)，優(yōu)化系統(tǒng)閉環(huán)響應(yīng)。最后介紹了實驗平臺的軟硬件設(shè)計，進(jìn)行了一系列實驗驗證本文的理論分析和仿真。實驗結(jié)果與理論分析和仿真基本一致，驗證了本文的正確性和可行性。
[Abstract]:Inductive contactless power transmission (ICPT) is a new type of power transmission technology. Because ICPT does not require the contact of conductors, it is widely used in underwater, flammable and explosive, dust-free workshop and other special occasions. ICPT has the characteristics of convenience and safety. Also has the widespread application in the transportation and the electronic product domain. In this paper, the main technology of ICPT system is studied, including the modeling of loosely coupled transformer, the analysis and design of compensation circuit, and the design of closed loop control system. In this paper, the loose coupling transformer (LCT) is analyzed, the leakage inductance model and mutual inductance model of the loosely coupled transformer are established, and the relationship between them is analyzed. The model of loosely coupled transformer considering loss is established, and the mutual inductance model of loosely coupled transformer is simplified by using the concept of mutual impedance. Mutual impedance simplifies the transformation relationship and loss analysis of the primary and secondary sides of a loosely coupled transformer. From the mutual inductance model, it can be seen that the compensation element should match the self-inductance of the original side when designing the compensation circuit. The compensation circuit of ICPT system is studied in this paper. Firstly, the design method of capacitor compensation circuit is analyzed, the design methods and applications of four kinds of capacitor compensation circuit are summarized, and the basic principles and steps of designing compensation circuit are summarized. Then, the characteristics of LCL circuit are analyzed, the relationship between LCL compensation circuit parameters and transmission power is analyzed, the design method of LCL compensation circuit in ICPT system is given, and the difference between secondary side LCL compensation and series compensation is analyzed. Finally, the primary edge equivalent circuit of LCL compensation ICPT system is analyzed, the relationship between original edge quality factor and transmission power is given, and the transfer function of LCL compensation circuit is deduced. In this paper, the closed-loop simulation of multi-load sliding ICPT system is carried out by Simulink. The efficiency of loosely coupled transformer and the switching mode of phase-shifted full-bridge converter are analyzed by simulation, and the conditions of soft switching are analyzed, the closed-loop control parameters are designed by simulation, and the closed-loop response of the system is optimized. Finally, the software and hardware design of the experimental platform is introduced, and a series of experiments are carried out to verify the theoretical analysis and simulation. The experimental results are consistent with the theoretical analysis and simulation, and verify the correctness and feasibility of this paper.
