It has been some time since the press conference of science and technology circle. Although the new mobile phone released by Apple this year did not meet the expectations of many people, it still could not prevent many fans from liking it. Although Apple has not officially launched a 3 in 1 wireless charger, the majority of accessory manufacturers have early introduced a family barrel charger that supports three coil wireless charging. In this article, I will explain the black technology of wireless charging coil.
Wireless charging mainly applies the principle of electromagnetic induction, and ends energy transmission through intermittent energy coupling of coils. During operation, the input terminal converts the communication mains power into DC power through full bridge rectifier circuit, or directly uses 24V DC power to supply power to the system. Through the coupling energy of two induction coils, the receiving conversion circuit converts the current output by the secondary coil into DC to charge the battery.
The three coil wireless charger is mainly equipped with the wireless charging coil produced by Mingda, which can effectively dissipate heat for the wireless charger. The Mingda coil can enhance the electromagnetic efficiency and meet the demand for fast charging. The Mingda coil uses a new polymer material magnet, which can enable the wireless charger to maintain its charging function in a more chaotic environment.
