Design and Implementation of Wireless Charging System for Mobile Phone
摘要
Abstract
A wireless charging system has been designed and implemented based on the half-bridge inverter technology and the magnetic induction coupling technology. The system is mainly consisted of four parts, including the power module, the rectifier filter module, the high frequency inverter module and the isolation transformer. By using multiple primary coils in parallel, the system can provide electricity for multiple mobile phones in the same time. The system performance is also improved by optimizing the coils of the isolation transformer. Testing results indicate that the designed system can overcome the shortcomings of similar charging systems using a single primary coil, such as insufficient charging area and low charging efficiency. The interference among different equipments to be charged can be reduced. The charging efficiency and voltage are almost equivalent for multiple electronic loads. The high electric energy transfer efficiency, the good safety and the low cost make this wireless charging system suitable for various applications.关键词
