【摘要】：感应式非接触电能传输(ICPT)是一种新型的电能传输技术，由于ICPT不需要导体的接触，因此在水下、易燃易爆、无尘车间等特殊场合有广泛应用。ICPT具有方便安全的特点，在交通运输和电子产品领域也有广泛的应用。 本文以多负载滑动式ICPT系统为研究对象，对ICPT系统的主要技术进行了研究，主要包括松耦合变压器的建模、补偿电路的分析与设计、闭环控制系统的设计。 本文对松耦合变压器(LCT)进行分析，建立了松耦合变压器的漏感模型和互感模型，并分析了两者之间的关系。建立了考虑损耗时松耦合变压器的模型，利用互阻抗的概念简化了松耦合变压器的互感模型。互阻抗简化了松耦合变压器的原副边转化关系和损耗分析，，从互感模型可以看出，设计补偿电路时补偿元件要与原副边的自感进行匹配。 本文对ICPT系统的补偿电路进行了研究。首先分析了电容补偿电路的设计方法，对四种电容补偿电路的设计方法和应用场合进行了总结，总结了设计补偿电路的基本原则和步骤。然后分析了LCL电路的特点，分析了LCL补偿电路参数与传输功率的关系，给出了LCL补偿电路在ICPT系统中的设计方法，分析了副边LCL补偿和串联补偿的区别。最后对LCL补偿的ICPT系统的原边等效电路进行了分析，给出了原边品质因数与传输功率之间的关系，并推导了LCL补偿电路的传递函数。 本文利用Simulink对多负载滑动式ICPT系统进行闭环仿真。通过仿真分析松耦合变压器的效率和移相全桥变换器的开关模态，分析了软开关实现的条件；通过仿真分析设计闭环控制参数，优化系统闭环响应。最后介绍了实验平台的软硬件设计，进行了一系列实验验证本文的理论分析和仿真。实验结果与理论分析和仿真基本一致，验证了本文的正确性和可行性。
[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.
