The power adapter, whose English name is Power adapter, is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit, and can be classified into an AC output type and a DC output type according to its output type; According to the connection method, it can be divided into wall-mounted and desktop. Widely used in telephone sub-machines, game consoles, language repeaters, walkmans, notebook computers, cellular phones and other equipment.
The power adapter, whose English name is Power adapter, is a power supply conversion device mainly used for small electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit.
Turn 220V AC into a low-voltage AC through a reduction transformer. 2. Using four diodes, the unidirectional conductivity of the diode is used to convert the alternating current into direct current (the size is variable). 3. Capacitor filtering is used to convert the DC power of varying size into a constant DC power.
Power adapter types can be roughly divided into two types:
1. A simple transformer, some have a certain voltage regulation function, and the output is AC. This type of electrical appliance has a rectifier circuit inside.
2. Voltage regulation and rectification, the output is DC. Such appliances do not have a rectifier circuit. The adapter in 1 is not available. As for the principle, there are two types of transformers and switching power supplies. Of course, there are also ultra-cheap capacitors.
According to the connection method: it can be divided into desktop type and wall type; according to the output current type classification: it can be divided into AC output type and DC output type. Widely used in notebook computers, mobile phones, home IT equipment and other equipment.
