The advantage of magnetic wireless charging technology is that the device can be firmly fixed on the magnetic base when charging and is not easy to fall off. At the same time, the magnetic base can be adjusted according to the needs of non-equipment, and the charging effect is more stable.
5, first of all, the principle of use is very simple, magnetic charging is through the magnet male and female suction, so that the charging cable and the jack can be connected to charge. Magnetic charging, as long as the joints are close to each other, the magnetic force will be firmly attracted for charging. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magneticWhen 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.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.

Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
The principle of mobile phone wireless charging is to use electromagnetic induction technology to pass electrical energy through the magnetic field in the airTransfer to the inside of the phone, so as to realize the charging of the phone. Specifically, wireless charging devices mainly include two parts: transmitter and receiver. The transmitter generates a high-frequency alternating magnetic field through a built-in coil, and the coil inside the receiver receives the magnetic field energy and converts it into electricity, thus charging the phone.
Conductor cutting magnetic sensationA line can generate electricity, and a static magnet cannot generate electricity. In the video of the "static magnet generator" circulating on the Internet, there may be a large coil under the desktop emitting a changing magnetic field, or a small motor under the desktop with a magnet rotating, you can't see, the coil cutting the magnetic field line on the desktop, so the light emitting tube will light up.
The magnet generator turns to produce electricity. Static magnet generator principle: By adding an AC voltage to the magnetizing coil, to change the direction of the magnetic field line of the closed magnetic circuit; And through the open magnetic circuit induced by a change in the direction of the magnetic field line of the closed magnetic circuitA change in the line of force to generate an electromotive force by electromagnetic induction in the induction coil.
Principle of magnet generator A magnetic generator, or magnetic dynamo, is a device that provides a high-voltage electrical pulse to a spark plug in the ignition system of a gasoline-powered internal combustion engine. Once used in all gasoline-powered cars, it is now restricted to lawn mowers, chainsaws, and internal combustion aircraft engines. The magnet generator turns and generates electricity. Power depends on the size of the generator. The motor has very little charge at 1,000 RPM. The big generators are non-magnet.
Principle of static magnet generator: by putting aAn AC voltage is applied to the magnetizing coil to change the direction of the magnetic field line of the closed magnetic circuit; And an electromotive force is generated by electromagnetic induction in the induction coil through a change in the open magnetic line induced by a change in the direction of the magnetic field line of the closed magnetic circuit.
The basic principle of magnet power generation: when the metal coil cuts the magnetic induction line in the magnetic field, it will produce magnetic induction electromotive force (voltage), from the microscopic point of view, if the voltage difference will form a current, and the direction of the current is opposite to the direction of the electron, there is a directional movement of the electron generated current, so that the object with electricity.
But there is no electricity, obviously the power generation in the video is fake. The winding of the coil in the video itself is wrong, because the two poles of the ring magnet are on the upper and lower planes, the magnetic field line is from one pole to the other pole, the coil plane in the video is parallel to the magnetic field line, there is no magnetic field line through the coil plane, which will generate current? At that time, I was puzzled by the results of the video, and now it is proved by experiments to be false, mysterious and boring.
The principle of electric field coupled wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
Wireless charging technology mainly uses the principle of magnetic field to transmit energy to achieve power transmission without physical connection between the power supply and the device. Its basisThis principle can be summed up in two ways: electromagnetic induction and magnetic resonance. In the electromagnetic induction mode, the transmitting end and the receiving end of the wireless charging device have a coil. When the coil at the transmitting end is energized, a magnetic field is generated.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then 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 AC power by 2M active crystal inverterThe primary winding.
Electromagnetic induction: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring the energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
Wireless charging technology from the radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways, its principle is through the near-field induction, the wireless charging device will be transmitted to the charging terminal device, the terminal deviceThe received energy is converted into electrical energy and stored in the device's battery. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones.
The main principle of wireless charging is the electromagnetic induction principle. It is charged in a non-contact manner, transferring electrical energy by generating a magnetic field between the charger and the device being charged. The following explains the principle of wireless charging in detail. Wireless charging technology is mainly based on the principle of electromagnetic induction. Specifically, when the AC magnetic field is generated on the charger, the electric energy is transferred to the device through the action of the magnetic field, and the wireless power supply is realized.
