Wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending and receiving end, and the sending end coil is connected to the cableThe power supply generates an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the transmitting end to generate a current to charge the battery. The wireless charging system mainly uses the electromagnetic induction principle, and the energy transmission is completed through the continuous energy coupling of the coil.

ThisThe circuit production is generally the use of pulse, to prevent coil overheating and short circuit at the power end need to use temperature detection and current detection and then real-time control of the pulse, of course, but also to protect the circuit.
2, can not, excessive increase in 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 contact, you have to change to radio wave type, within five meters.
3, the secondary winding is broken, the wireless charging coil has two windings, one isThe 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.
I just bought a double coil, the mobile phone does not need to be put on the whole, horizontal and vertical can be put. But the single coil must be aligned with the phone to charge it.
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 charging speed, increasedCoil is equal to increase the resistance, it will make the current slow, coil is proportional to the winding, too much too little can not, coil winding less, there will be damage to the parts, resulting in parts burned spark, because do not be free to modify the wireless charging base.
Hello, about whether magnets will be used in the wireless charger. First of all, you must understand the principle of wireless charging, that is, electromagnetic induction, through the magnetic flux between the two coils is constantly changing, to transfer energy, and electromagnetic induction in order to make the coil magnet more concentrated, usually the use of iron core these materials with large permeability to reduce energy loss, so,There is no need to use magnets inside the wireless charger.
Control chip: manages the entire wireless charging process, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
Using this feature, two-way power supply can be realized by further improving the circuit composition. In general, if the inverter is set on the secondary side to achieve reverse power supply, andThere will be problems with the combined electric container. Abe et al. 's research group solved this problem by adding a reactor to the secondary side circuit and fine-tuning the capacitance value of the series capacitor in the primary side coil, thus achieving two-way power supply.
This is the end of the introduction of dual coil wireless charging principle and wireless charging single coil and three coils, do not know you find the information you need? If you want to know more about this, remember to follow this site. < / p >
