Factory Customized 220V 1800W Induction Cooker Heating Coil
This type of charging coil, essentially an antenna, has a number of indicators, such as impedance, frequency, etc. There are two kinds of transmission and reception. There are close distance, there are long distance, but considering electromagnetic radiation, or with close distance (2-3mm) appropriate, there are also more manufacturers to support. Second: the transmitting and receiving coils should have the same resonant frequency and be used in pairs, that is to say, the QI standard is a relatively wide band (110khz-205khz).
Different terminal, transmitting coil antenna and receiving process is different. If the environment of transmitting antenna installation is permitted, some thick copper wire and multi-layer winding can be used, that is to say, the antenna thickness is not particular about. But the receiving antenna, depending on where it's installed, has to be super thin. On smartphones in particular, only the inside of the case has room for installation.
According to the type of receiving terminals, 120W is used for notebook computers and 5W is used for mobile phones.
The best place to install the wireless charging coil antenna in the phone is on the inside of the phone shell. Because of the large charging gap, the charging efficiency will be low, a micron corresponding to about 0.1mA current loss, 1000 microns (1mm) will lose more than 100 mA.
Mobile phones in the wireless charging coil behind must be added magnetic isolation materials, there are inorganic magnetic materials. Such as PC44 and organic series materials. Inorganic, sintering process, easy to break, not suitable for sticking on the phone case, because it is easy to damage, and the flat diameter of a piece of 40mm, installed on the curved case, not suitable. So this kind of inorganic magnet can only find space on the circuit board. While the organic magnetic material can be bent, four corners have positioning holes, mobile phone shell inside the plastic positioning pillar can be extended, stuck in the positioning hole, so that easy installation.
Antenna to determine the number of turns, antenna manufacturers need to take the terminal to test, debug the best parameters, so that the charging efficiency is high. This is the same process as making a mobile phone's built-in antenna.
