This article to talk about manganese zinc ferrite wireless charging, and manganese zinc ferrite toxic 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, What are the characteristics of wireless charging?
1, the advantages of wireless charging safety: no power contact design, can avoid the danger of electric shock. Durable: the power transmission element is not exposed, so it will not be eroded by moisture and oxygen in the air; There are no contacts and therefore no mechanical grinding during connection and separationDamage and loss caused by flaring, etc. 2, the main features from the theory, wireless charging technology, safe and harmless to the human body, the resonance principle of wireless charging is magnetic resonance, only in the same frequency resonance between the coil transmission, and other devices can not accept the band, in addition, the magnetic field used by wireless charging technology itself is harmless to the human body.
3, vivox100s wireless charging features: convenience: wireless charging saves the trouble of carrying the charging cable and plugging the data cable, making the charging process more simple. Compatibility: The phone supports a variety of wireless charging SettingsB, users can choose the right charger according to their needs. High efficiency: Wireless charging technology uses advanced electromagnetic induction principle to achieve efficient charging speed.
4, wireless charging is characterized by no charging line restrictions, affected by nickel-metal hydride batteries, this battery has memory, the best way to use is to use up after charging to achieve the best state of the battery. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable. This is more conducive to maintaining the best performance of the lithium battery, without waiting until it is used up and then charging it, and without charging it too fullChanging the proportion of trace additives during the feeding process can adjust the characteristics of the product within a certain range.
2, the range of inductors and transformers is very wide: the working frequency can be power frequency (50Hz), it can also be radio waves (such as several hundred MHz or more); At low frequency, silicon steel sheet is used as the iron core, at high frequency, ferrite is used as the magnetic core, and the hollow coil is used at high frequency. The magnetic circuit can be open at high frequencies, such as ferrite and hollow core coils, and closed at low frequencies, such as ferrite and ferrite cores.
3, high frequency transformer and low frequency transformer design principle is the same, onlyThe materials are different and the working environment is different.
Notes for winding coils mainly include the selection of coils with different frequency characteristics, the selection of magnetic cores of different materials, and the consideration of parameters such as inductance and distributed capacitance of the coil. In the wireless charging receiving coil, according to its working characteristics in the audio segment, silicon steel sheet or permalloy is usually selected as the core material.
Finally, after confirming, put the phone on the wirelessCharger, will display charging tips, you can. Precautions for wireless charging: Do not place metal objects, magnetic stickers, magnetic cards and other foreign objects between the mobile phone and the wireless charger (such as the car magnetic bracket iron attached to the back of the mobile phone). The mobile phone may not be charged properly or be damaged due to overheating. Place the mobile phone correctly. If the wireless charging coil deviates too much, the charging efficiency may be low or it cannot be charged.
First of all, according to the needs of the circuit, select the winding method: First of all, determine the size of the inner diameter. Then according to the inductance value and resistance and other factors to determine the coil layer number, height, outside diameter and so on. Wireless charging coil for short wave,In the medium wave loop, its Q value can reach 150-250, and has high stability.
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.
The secondary winding is broken, and the wireless charging coil has two windings, one is the main winding and one is the secondary windingAfter the secondary winding is damaged, it will cause the main winding to heat up, and the output has no voltage.
The size of the current is related to the thickness of the coil, as well as the frequency. Look at the specific circuit, sometimes when the difference in inductance value is not large, the impact on the output voltage and current is not obvious, but it may lead to a large difference in the change in unit period voltage/current, and also lead to the difference in loss and efficiency, so the choice of inductor is reasonable at this time, mainly to see whether it can get better performance under the premise of meeting the size specifications.
