2, wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
3, can not, too much increase the voltage or increase the number of turns will burn the battery, because you turn more voltageThe higher it is, I don't know if your homemade charger is Qi program, if it is Qi, it is not possible, this must have close contact, you have to change to radio waves, within five meters.
This circuit production is generally the use of pulse, to prevent coil overheating and short circuit at the power end need to use temperature detection and current detection and then real-time control of the pulse, of course, but also to protect the circuit.
Electromagnetic induction is the primary choice for wireless charging systemIn principle, continuous energy coupling through the coil completes the transfer of energy. When the system is operating, the input end converts the communication mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After the wireless charger coil passes through the power supply module, the output direct current is converted into high frequency communication power supply through the 2M active crystal inverter.
During the dismantling process, it was found that the internal design of the product was fine, including magnetic ring buck inductors, multiple capacitors and efficient buck converters, ensuring performance and stability. The USB-C interface uses Tual microsynchronous step-down chip, and the USB-A interface uses TMI2282L, coupled with Huineng Tech's protocol chip, provides powerful wired charging capability. The whole wireless charger is ideal for the desk due to its practicality and efficiency.
