Qi wireless charging is a contactless power transmission method based on the principle of electromagnetic induction. Qi standard wireless charging coil is mainly composed of primary coil (or transmitting coil) and secondary coil (or receiving coil)
When AC power is connected to the primary coil, a magnetic field is generated, and the secondary coil induces alternating current due to the existence of alternating magnetic field, so as to realize the wireless transmission of electric energy and conversion to charge equipment .
The commonly used wireless charging coils include:
1 Single coil: A5 coil, A10 coil, A11 coil
2 Multi-coil: A6 three-coil, A28 two-coil, A28 three-coil
Huizhou Ming Da Precise Electronics Co., Ltd is a manufacturer of wireless charging coils, which can design and customize wireless charging coils for customers.
