Today to share the knowledge of wireless charging circuit, which will also explain the principle of wireless charging road, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>2, one of the self-wound coil connected to the charging circuit, 555 output pin (third pin) connected to oneThe output tube (at your own will, but to the high-frequency power tube) the output tube is linked to the self-winding coil, and the connected two coils are close (about 1 cm or so there is a very sufficient charging current). The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
3, principle: the DC-DC switching power supply is divided into two parts at the high-frequency transformer, using resonant coupling; Then use RFID technology for data communication and current feedback. In single-phase bridge rectifier circuit, if there is a filter capacitor, when the load is open,The output voltage (that is, the voltage at both ends of the capacitor) is the peak of the AC input voltage, that is, U output =414*U input, that is, the input voltage of the root 2 times.
4, what are the components of wireless charging? The left side is TX, that is, the transmitter, and the corresponding product is the wireless charging transmitter. On the right is Rx, that is, the receiving end, and the corresponding product is a mobile phone with wireless charging function. TX end: MCU, power full bridge, and LC resonant Tank composed of inductors and capacitors, where the inductor is the transmitting end coil.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be 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.
2, wireless charging system mainly uses the principle of electromagnetic induction. The wireless charger refers to the terminal that needs to be charged without the traditional charging power cordThe charger on the standby, 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, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that by encircling the wire into a ring, or even winding it into a coil, the magnetic field generated will be stronger and more concentrated, which is called "current magnetic effect.Yes ".
4, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
5, wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to be like a traditional wired chargerA transmission cable is needed to transmit electricity to the device, but the device that needs to be charged can be charged by contacting the wireless charging base.
6, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
1, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and noThe wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below. 2, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

Mobile phone wireless charging technology, derived from wireless power transmission technologyAfter the switch, the electromagnetic circuit converts the electrical energy of the power supply battery into a large amount of magnetic energy, and then uses a reverse coil (the international standard brick QI coil) to receive this large amount of magnetic energy, converts it into electrical energy, and passes through a metal output head to our equipment reserve battery. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.

Radio wave type: The principle is to convert environmental electromagnetic waves into current and transmit current through the circuit. The transmission distance of this wireless charging method is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. However, because of the low conversion efficiency, if you use this method, the charging time will be longer. Focused light: This is a new wireless charging developed by MicrosoftTechnology "AutoCharge".
