Specification for wireless QI fast charger

Smartphone is not only a communication tool, but also our work assistant, entertainment center and life partner. What supports the operation of mobile phones is the seemingly insignificant phone charger. Today, let’s talk about USB fast charger and see the scientific principles and technological progress behind it.

The core components of stand holder wireless charger are power electronic semiconductor devices, and their main function is to convert alternating current into low-voltage direct current. This process seems simple, but in fact it involves many profound theories of power electronics. First of all, the voltage and current of alternating current change with time, while direct current is constant. Therefore, the charger pin types needs to convert the alternating current into pulsed direct current through a rectifier, and then convert the pulsed direct current into smooth direct current through a filter. In addition, the iphone quick charger also needs a voltage converter to reduce the voltage to a level suitable for charging mobile phones.

Wireless charger plug can not only provide powerful power to charge mobile phones quickly, but also has the advantages of small size and easy portability. This is because issues such as power supply efficiency, thermal effects, and electromagnetic compatibility need to be taken into consideration during the design and manufacturing process of the charger. In order to improve the efficiency of the power supply, USB adapter usually use switching power supply technology to store energy in the inductor or capacitor through the switching action of the switch tube, thereby reducing energy loss. In order to solve the problem of thermal effects, USB battery charger usually adopt efficient heat dissipation designs, such as metal casings, heat sinks, and fans.
