[Abstract]:With the rapid development of technology, mobile phones, digital cameras, tablets and other handheld devices have become an essential part of people's daily life, and the pace of upgrading is particularly rapid.Such a rapid change of frequency will bring a serious problem, that is, waste electronic products pollution to the environment.Every time a user changes a mobile phone, the old phone charger is basically abandoned.Because the wired charger is not easy to carry and the damage of the connector can cause the danger of electric shock, the research on wireless charging and high energy transmission efficiency has become a trend.Wireless charging technology is produced when electronic products are updated, reducing the generation of waste chargers. The generality and compatibility can effectively reduce the environmental pollution of waste chargers, and will make people's lives more convenient.Based on the principle of electronic induction, a wireless charging system for mobile devices is designed.The transmitter control chip of the system uses BQ500211A199A199ART9818A and MSP430G2001 chips to design the hardware circuit, including the full-bridge inverter line, LED control circuit and other protection circuits, and the receiver design module uses SN51013B chip to design the circuit.In the design of the system, the influence of the transmitting coil, the receiving coil and the contact distance on the system performance is fully considered. By adjusting the design of the coil continuously, the voltage dynamic adjustment and the resonant frequency adjustment, the system performance is greatly improved.The maximum transmission power of the system is 5 W and the effective charging distance is about 1cm.The first chapter introduces the background, principle and current situation of wireless charging technology, the second chapter is the design and implementation of wireless charging system, from the transmitter design,The design of the receiver and the coil are described in detail. The third chapter is the function verification of the wireless charging system. The parameters of the transmitter and receiver are tested to meet the Qi standard design, and the test results are analyzed.The fourth chapter is a summary and prospect, mainly aiming at the design experience of this subject, put forward some views on the development of the whole wireless charging system.
