Recent magnetic resonance (MagneTIc Resonance; MR) wireless charging technology visibility has increased significantly, Wireless Power Consoration (WPC) and wireless charging solution camp A4WP (Alliance for Wireless Power) recently released the 1.2 specification almost simultaneously, propaganda support magnetic resonance Wireless charging technology. Among them, WPC's 1.2 specification is more backward compatible with 1.1 magnetic induction technology. It is obvious that the two camps are occupying the application market of magnetic resonance technology, and it also shows that magnetic resonance technology is the future development direction.
In fact, in practical applications, magnetic resonance technology can better solve the problems of energy transmission distance, position without alignment, high transmission power and better long-distance transmission efficiency, and various applications have sprung up. In order to solve the problems that many places in the past are limited by the appearance of wired power supply, dustproof and waterproof, and reliability of repeated plugging and unplugging, magnetic resonance wireless charging technology is rapidly being applied to electric vehicles, medical equipment and even military equipment, and consumer goods. Due to the official built-in wireless charging of Samsung, LG and other companies, Apple iWatch watches also use wireless charging, and the market is hotter.
The most interesting application market for wireless charging is the application of smart mobile products. The new generation of smart mobile products pursues smaller size, is more convenient to use, has excellent design, and has an annoying charging problem that has plagued product designers. Through wireless charging technology, not only smart products can be placed and charged at will, the charging interface will not be damaged due to corrosion and multiple plugging, and it can meet the design requirements of waterproof and dustproof, plus the efficiency and transmission power of current wireless charging technology. Already able to meet the needs of most mobile devices, the integration of wireless charging technology can greatly enhance the consumer experience has become the focus of various equipment manufacturers.
The Wattfly wireless charging brand under Team Group is one of the few companies with exclusive magnetic resonance technology. In addition to the common Qi magnetic induction wireless charging products, it also focuses on the development of magnetic resonance wireless designed for various industrial applications. The charging module, the product solution covers medical, military, wearable devices, sensors, smart tablets, outdoor three-proof products, toys, lamps, furniture, etc. The currently published module products are leading the market in terms of specifications, and the cost is even more low. Recently, Wattfly released the world's first A4WP Rezence standard transmitter and receiver charging module set, and plans to develop multi-mode wireless charging products to meet market demand.
At present, the mainstream of the market is magnetic induction (MagneTIc InducTIon; MI) products, but after the release of the WPC1.2 specification, it has also turned to magnetic resonance technology, focusing on smart mobile devices, game peripheral products, wearable computing products. The magnetic resonance product has the characteristics of long transmission distance, high long-distance efficiency, and the ability of one transmitter (charging board) to simultaneously charge multiple receiving devices, and becomes the future development direction of the wireless charging market. Many internationally renowned enterprises have invested in research and development. . However, magnetic resonance technology has higher technical difficulty for magnetic induction technology. Higher frequency makes power management and resonance control more difficult, and mass production technology also faces challenges. This is also the only market that has very few enterprises to master core technologies. the reason.
In terms of working principle, the working principle of magnetic induction technology is constructed on the Faraday's law of electromagnetic induction. The alternating magnetic field is generated by the alternating electric field, and the induced current is generated by the change of the magnetic field. The intuitive understanding and common transformer principle differences Not big, this method is characterized by simple working principle and relatively mature technology, but the disadvantage is that it is limited by the characteristics of electromagnetic induction. The working distance of the primary and secondary coils is difficult to break through, and it is easy to produce metal heating (with the working principle of the induction cooker) ). The principle of magnetic resonance technology is to transmit energy through the resonance of an antenna with the same resonant frequency. The intuitive understanding is that a tuning fork is struck, and the same monotonous tuning fork in the vicinity will also vibrate due to the influence of resonance. Energy can be transmitted very efficiently between objects of the same resonant frequency, while objects of different frequencies absorb energy substantially.
When the resonance frequencies of the two objects are the same, the energy will increase with the vibration, and more and more energy will be generated in the system. This is like when we swing, just sit on the top and let the legs sway synchronously. The principle that can bring power to the swing is similar. We swing the feet to drive the swing of the body and the swing. Magnetic resonance technology uses a weakly coupled magnetic field to induce resonance of the secondary coils of the same frequency to achieve resonant transmission of energy.
Magnetic resonance technology is characterized by the ability to easily realize long-distance wireless energy transmission, and can simultaneously transfer energy from one transmitting coil to multiple receiving coils, and the energy transfer can be bidirectional. If the system requires it, it can also be reversed by the receiving coil. Come over to transfer energy to the transmitting coil. Since the magnetic field of magnetic resonance technology is used to induce resonance rather than directly transfer energy from a magnetic field, the magnetic field radiation generated when transmitting the same energy is much smaller than that of magnetic induction technology, and it also reduces concerns about health effects.
The design of magnetic resonance wireless charging system needs to master advanced technologies such as antenna design capability, ultra-high frequency power control system and resonance management technology. As a very small number of masters, Wattfly provides module customization services and can design for various products. Provide a dedicated solution.
