Magnetic wireless charger with 5 coils, 3in1 wireless charger with dual charging10W charger wireless
Recent. Our engineers have developed the industry's first magnetic 5-coil wireless charger solution.
We added C-shaped bipolar S-N magnets on the upper and lower positions of each coil. Take Apple 12 as an example. Provide up and down positioning for mobile phones with built-in magnet positioning. It can accurately position each coil and avoid the phenomenon of inaccurate up and down deviation.
The 5 coils are lined up in a superimposed way. Increase the charging area of the mobile phone. Within these 5 coil areas. The receiving coil in the center of the mobile phone induces any one of the transmitting coils on the base to realize wireless charging.
This structure greatly improves the phenomenon that the mobile phone cannot be aligned when charging.
Explanation about the working principle of 5 coils:
For example, No. 5 coil is working (the light on the right is on). No. 3 and No. 4 coils stop working. Any one of coils 1 and 2 can drive a charging device.
For example, No. 4 coil is working (the light on the right is on). Coils 2, 3, and 5 stopped working. 1, No. coil can drive a charging device,
For example, the No. 3 coil is working (the lights on the left and right sides are on). No. 1, 2, 4, and 5 coils all stop working. Only one device can be charged, this is when the phone is placed in the middle of the product. It will not cause other coils to report FOD, and avoid generating excess heat.
For example, No. 2 coil is working (the light on the left is on). Coils 1, 3, and 4 stop working. Coil 5 can drive a charging device,
For example, coil 1 is working (the light on the left is on). Coils 2 and 3 stop working. Any one of coils 4 and 5 can drive a charging device,
5 coils are controlled by a high-performance chip. The 5 coils are divided into two groups of drive circuits.
The first group of driving circuits are coils 1, 2 and the second group of driving circuits are coils 3, 4, and 5. Each group can only drive one charging device. Two groups can drive two charging devices at the same time, and each group has a maximum power of 10W，
