K-040 18W Power Adapter

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.

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 220 volts in the home into a stable low voltage of about 5 volts to 20 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 input 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 220V 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.
