Electric field coupled wireless charging, the principle is to transmit power by coupling two sets of asymmetric dipoles in the vertical direction to generate wireless fast charge definition inductive electric field. Suitable for short distance charging, conversion efficiency is also high, the position can not be fixed wireless fast charge definition ; However, the disadvantage is that it requires a large volume of equipment and less power.
The first is field-coupled charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. Transfer effectThe rate is good, but there are distance limitations, and large capacity charging stations are required. The second type is magnetic resonance charging, which is different from the above electric field. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. 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 power supply coil) will generate a magnetic field, its wireless fast charge definition he is not powered on the coil (mobile phone side byProximity to the magnetic field generates an electric current that charges the phone.
What is the principle of wireless charging? Will wireless charging become popular? The principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy, which is stored in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface.
Wireless fast charge is the use of electromagnetic induction principle, there is a coil in the sending and receiving end, the sending end coil is connected to the wired power supply to generate electromagnetic signals, and the receiving end coil inductionThe electromagnetic signal at the sending end generates a current to charge the battery, which can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
