This article to talk about the advantages of wireless charging single coil scheme, as well as wireless charging double circle or single circle is good corresponding knowledge points, I hope to help you, do not forget to collect the site oh. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, How does wireless charging work?
The basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the airIt is converted into current and transmitted to the intelligent terminal. 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.
Wireless charging system mainly adopts 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, by using the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will beBecome a bridge connecting charging base stations and devices.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile deviceWireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the phone interface, which can better protect the phone interface. Safety: With a variety of protection functions, such as: overcharge and overdischarge, metal foreign body detection and other functions, always protect the safety of users.
3, What are the advantages of wireless chargers? Compared with traditional wired charging, it shows a better experience than traditional chargers in terms of safety, flexibility and versatility. Flexibility, convenience: non-contact, one-to-many charging compared with the general charger, reduces the trouble of plugging and unpluggingAlso avoid the interface is not applicable, poor contact and other phenomena. Although the poor contact caused by wired charging is not common, wireless charging basically does not have this hidden danger.
4, advantages: The advantage of wireless charger is that we can use the mobile phone at the same time to charge, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
5Convenience: When the phone is charging, the phone comes in but it is not convenient to answer in some specific situations. At this time, the convenience of wireless chargers is reflected. Simply pick up the charging case and move it to any place where the user can easily answer the phone.
6, advantages: In order to improve the unity of the mobile phone, most mobile phones are no longer with the design of the headphone hole, but many users said that the cancellation of the headphone hole design is not humanized. But with the wireless charger, we can directly put the phone on it, bring headphones to listen to music, but only limited to listening to music, want to play games that isNot very realistic.
1, advantages: non-contact, no wire, mobile. Disadvantages: short distance, small power, poor efficiency. Low efficiency: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power.
2, advantages: the use of wireless magnetic induction charging equipment can be invisible, the equipment wear rate is low, the application range is wide, the public charging area is relatively reduced; High technical contentIt is easy to operate and can implement relatively long distance radio energy conversion. Disadvantages: Although the equipment has high technical content, the economic cost of the equipment is higher and the maintenance cost is large; Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high.
3, the shortcomings of mobile phone wireless charging although the technical content of the equipment is high, the economic cost of the equipment is high, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
Wireless charging base to increase the coil, or do not modify it, you increase the coil not only did not play a good effect but affect the speed of charging, increase the coil is equal to increase the resistance, it will make the current slow, the coil is proportionally wound, too much or too little can not, coil wound less, there will be damage to the parts, resulting in parts burned spark, For some do not arbitrarily modify the wireless charging base.
Wireless chargingWill not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
Can not, too much increase the voltage or increase the number of turns will burn the battery, because the more you turn the higher the voltage, I do not know whether your self-made charger is Qi program, if it is Qi, it is not possible, this must be close to the connectionTouch? You need to switch to radio. Anything within five meters.
Mobile phone charging base generates high-frequency alternating magnetic field, when the mobile phone is placed on the charging base, the alternating magnetic field will generate high-frequency alternating voltage inside the mobile phone through the induction coil, and then through the rectifier circuit in the mobile phone to convert the high-frequency alternating voltage into direct current to charge the mobile phone.
Mobile phone space charging technology is to install the transmitter coil on the wireless charging base, and install the receiver coil on the back of the mobile phone. When the mobile phone is charged near the charging base, the transmitter coil will generate alternating magnetic field due to the access of alternating current. Changes in the magnetic field will allow receptionAn induced current is generated within the coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process.
The secondary winding is broken, the wireless charging coil has two windings, one is the main winding, one is the secondary winding, after the secondary winding is damaged, it will cause the main winding to heat, and the output has no voltage.
