Abstract Now，with the rapid progress of science and technology, various functions of the mobile communication devices become more perse. as a portable phone which is loved by numerous and much people of all ages, but with the popularity of the modern smart phones, to have one or more aircraft is a common phenomenon. But each phone have to have a match with its charger. Thus both wired charger because recycled USB cable plugs leading to varying degrees of damage or wear is not strong, in the case of a large electric field resulting in leakage, which has a certain degree of risk. Products also because the data cable and make the entire charging process is inconvenient, and to some extent, increase the added cost of the product. People's needs to promote the innovation and technology, through the many research scientists, wireless charging technology has been gradually progress. Wireless charging technology as a shining star in the future is likely to become a leader in the consumer field. Wireless charger potential as a consumer market share in the near future to completely replace existing wired charger.
The thesis of the wireless charging technology based on electromagnetic induction type did some research. Its main contents concentrated in the following points:
First, an overview of the wireless charging technology development and technical difficulties; system outlined several major principles of applied technology at this stage of mobile wireless charger; conduct a detailed analysis of electromagnetic induction wireless charging, including the entire principle of the charging system, various parts The principle introduced by analyzing theoretical analysis and calculation of specific parameters designed hardware schematics and PCB; the main system simulation and create a corresponding physical; Finally, analysis of safety issues that wireless charging system, the wireless future Charging technology outlook.
Keywords: Electromagnetic induction Wireless Charging system Electromagnetic induction parameters
