中文摘要 | 无线能量传输技术是指借助空间中的无形介质(电场、磁场、电磁波、激光、超声等)来实现电源与用电设备之间的能量传递,是一种较为理想的供电方式,在医疗植入器械、机器人、无线传感器以及各种电气设备中具有广阔的应用前景,然而传输距离与传输效率之间的冲突一直是制约该技术进一步商业化的最大障碍。磁耦合谐振无线能量传输技术是近年来的新兴技术,相比于微波、激光、感应耦合式等相对成熟的技术,磁耦合谐振式以传输距离适中、传输效率高以及辐射损耗低等特点,在面向日常生活中电气设备的供电需求表现出更高的实用潜力。但目前对该技术的研究程度还不足以满足实用化需求,特别是磁耦合谐振无线能量传输系统在特殊范围内所表现出的低效性,需要有针对性的提出解决方案来提高系统的实用性;同时系统因额外引入两组线圈使得系统参数在设计中表现出更为复杂的耦合关系,缺少各参数间的约束关系以及明确的设计原则,需要对系统内各参数之间的耦合关系进行详细分析,明确系统设计流程以及在各个阶段中的约束关系,为系统设计提供理论基础。针对上述问题,本文以理论分析、有限元仿真和实验测试为方法,在系统模型、临界耦合状态、设计约束以及传输特性等方面开展相关研究。 |
英文摘要 | Wireless power transfer technology refers to the use of space intangible medium (electric field, magnetic field, electromagnetic wave, laser, ultrasonic, etc.) to achieve the power transfer between the power source and electrical equipment,which is an ideal way of power supply, and has a broad application prospect in the medical implanted devices, robotics, wireless sensors and various kinds of electrical equipment. However, the conflict between the transfer distance and transfer efficiency is the biggest obstacles restricting the further commercialization of the technology. In recent years, magnetic coupling resonant wireless power transfer technology is a new kind of technology. Compared with the relatively mature technology, such as microwave, laser, inductive coupling etc, magnetic coupling resonant has shown potential application in the field of electrical equipment used in daily lives, because of moderate transfer distance, high transfer efficiency, and low radiation loss. Nevertheless, at present, the research of the technology is insufficient to meet practical demands, especially in a particular range, the magnetic coupling resonant wireless power transfer system is inefficiency, which need to targeted propose solutions to improve practicability of the system; At the same time, the system parameters show more complex coupling relationship in the design since the two additional groups of coils has been introduced. The lack of the constraint relationship among the parameters and design principles, a detailed analysis on the parameters of the coupling relationship is needed, and the system design flow and constraint relation in the design stage should be clear, which can provide theoretical basis for system design. In response to the above problems, based on the theoretical analysis, FEM (Finite Element Method) and experimental measurement, this paper focuses on the system model, the critical coupling state, design constraints and transfer characteristics and so on. |
