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 handIn the computer industry, the "Qi standard" is the most common, and Qi labels are often used to mark the packaging of many mobile phones and wireless chargers.
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, 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.
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 technology "AutoCharge" developed by Microsoft.
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 24V direct currentThe terminal directly supplies power to the system. 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, 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.
Generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, the Danish scientist Elster observed that if a piece of wireWith an electric current, a magnetic field will be generated around it, which will deflect the needle. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."
