Development of wireless charger coil

For the consumer market, the magnetic induction (Magnetic Induction, referred to as MI) or magnetic resonance (Magnetic Resonant, referred to as MR) arealternatives. No matter which direction the consumer market, a known fact is,wireless charger coil will be used. In the main push mobile phone provider,wireless charger coil will begin to permeate to the mobile phone market ecosystem. Computing has a strong ecological system will follow, the use of wireless charging technology to enter the next stage of growth. After that, the wireless power supply technology is likely to be extended to the infrastructure to support mobile phone and computing solutions in. How to use the wirelesspower supply technology for future architectures and solutions, the application will be only a beginning.

On the magnetic induction technology is concerned, there are two mainpopular specification: Wireless Power Consortium (Wireless PowerConsortium, referred to as WPC) and power transaction Alliance (PowerMatters Alliance, referred to as PMA). The two specifications are quite mature,many products are now used in the consumer market. The Wireless Power Consortium (Alliance for Wireless Power, referred to as A4WP) is the firstbased on magnetic resonance technology specification. These specificationsand solutions are raised some questions, for example, the wireless power supply technology will which direction to development? What is the best solution?

Mobile equipment

Convenience is one of the key factors to promote consumption of mobilesolutions in the use of wireless technology. Mobile phone, tablet computer,media player, mobile TV, mobile devices such as the different needs of different kinds of interface connector adapter, this means that in order tocharging for mobile devices, you need to carry a lot of different connector and adapter. Universal wireless adapter has a strong supportive infrastructure and ecological system, can solve these needs. Provide wireless charging in the car, Coffee shop, library, restaurant, train, plane, units, will satisfy the convenience of all the required.
