Newest 18W 18V 1A 6V 3A 9V 2A Power adapter

Product Description

Power adapter, also known as external power supply, is a power supply voltage conversion device for small portable electronic equipment and electronic appliances. It is commonly used in small electronic products such as mobile phones, LCD monitors and notebook computers. The function of the power adapter is to convert the high voltage of **0 volts in the home into a stable low voltage of about 5 volts to *0 volts that these electronic products can work, so that they can work normally. The power adapter is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is to convert AC to DC output; it can be divided into wall adapters and desktop adapters according to the connection method.
The working principle of the power adapter is as follows:
1. Convert the **0V AC to a low-voltage AC through a reducing transformer.
2. Using 4 diodes, the unidirectional conductivity of the diodes is used to convert the alternating current into direct current (the size is changed).
3. Use capacitive filtering to change the DC current with varying size into a constant DC current.
