Wireless Charging Circuit Design And Application Research

In science and technology developed today, our country is still in the early stages of the development of science and technology. As the electronic information industry upgrading, gradually improve the popularity of various kinds of electronic products, high-end intelligence, the emergence of the multi-core domestic product means that the burden of batteries gradually aggravate, battery as the leading factor of restriction on the use products. The popularity of various digital products, let people can not think of an important question: how to make the charging easier? This leads to the topic about wireless charging technology. Despite the mobile charger,carry not convenient, manufacturers do not match the charging interface, and result in the attachment also need to match, makes want to charge at any time impossible. When there are multiple terminals need charging at the same time, multiple sockets, multifarious attachment increased security hidden danger. Do not match the interface cable charging, plug, shorten life span, even more crucial problem is that as explore study space is expanding, many high-end space and underwater instruments also need to maintain power, while the charging cable can meet the requirements. So we put forward the concept of wireless charger and inevitable for a wide range and promotion.Wireless charging is using the electromagnetic induction principle, the transmitter and the receiver each have a coil, electromagnetic signal transmitting terminal cable power supply, the receiver induction electricity to recharge the battery. This is a very feasible solution, it is different from the previous cable charging, save multifarious wires, through the adoption of wireless charging technology, public mobile charging stations will likely become a reality, has certain advancement.Is to achieve the purpose of this subject can meet for real time digital devices such as mobile phone, wireless sensor network node is installed on the receiving end of such as area, through monitoring and observation in the process of wireless charging, how in the case of long distance transmission. In aspect of design, the use of chip SI1000 as main control chip. The collected data to the master control chip, data through radio frequency unit sent the receiver, and the monitoring system for real-time monitoring of battery is full of.
