2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charging usually adopts electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Traditional wireless charging solutions: In general, the traditional way of charging is to use electromagnetic induction to complete. That is to say, when the current flows through the charging coil of the charger, a corresponding magnetic field will be generated. The receiving coil in the mobile phone can generate current by sensing changes in the magnetic field, thus realizing wireless mobile phone charging. This charging method is indeed more convenient, at least to solve the problem of charging line loss, but also save a lot of space.
MOTOROLA built a breakthrough system based on Qi technology, which not only makes charging wireless, even inIt also has background power in the pocket. However, this technology requires extremely high spatial accuracy, and any object that intervenes will interrupt the charge. To address this challenge, MOTOROLA joined forces with GuRu, an innovative company focused on improving charging efficiency.
1, it uses the principle of magnetic coupling, the electrical energy from the transmitter to the receiver, so that the battery can be charged. When used, you only need to support wirelessThe charging mobile phone is placed on the wireless charging board to achieve wireless charging without the need to connect through the data cable. In addition, the wireless charging board also has the advantages of small size, light weight and strong portability, which is very suitable for use when going out or traveling.
2, first of all, wireless charging board is a common way to achieve wireless charging, it is based on the principle of magnetic coupling, just place the mobile phone that supports wireless charging on it, you can charge without data line. This device is lightweight and portable, especially suitable for use when going out or traveling, providing users with great convenience. Secondly, for car users, wireless charging stands are a good solutionCase. 3, the mobile phone does not have the function method is as follows: you can buy a mobile phone case that supports wireless charging, and install it on the mobile phone, the advantage of this method is simple and convenient, there is no need to replace the mobile phone or disassemble the internal phone, the disadvantage is that it may increase the weight and thickness of the mobile phone, as well as affect the heat dissipation and signal of the mobile phone.
