The Study Of Wireless Charging System With Coreless Printed-Circuit-Board(PCB) Transformers

With the development of science and technology, a variety of portable electronic products become more and more popular, such as mobile phones, digital cameras, notebook PC and so on. In reality, each electronic product has a matched charger. However, it will not only increase the cost of products and waste resource, but also be harmful to the environment. What's more, as all those chargers are not universal, it causes troubles to the users. Moreover, the majority of electronic chargers are wired, so charger is relatively inconvenient for the users. The wireless charger with a unified standard has the following advantages: convenience, shared charger to different electronic products.Therefore, this thesis has done some research on a wireless charging. It mainly focuses on the following areas:Outlining the development of the theory and the technology of wireless charging system; Analyzing the key technology affecting wireless charging system; especially giving the design of energy transfer termination (primary side); Discussing the methods of wireless charging system to improve the charging efficiency. According to the shortcomings of the system, the future wireless charging technology is prospected.Finally, summarizing main content of the thesis; clarifying the value and significance of this research.
