What is the function of an adapter?

The adapter is a power conversion device for small portable electronic devices and electronic devices. It generally consists of housings, transformers, inductors, capacitors, control ICs, printed circuit boards and other components. Its working principle is to convert the AC input into the DC output; Depending on the connection method Can be divided into wall type and desktop type. Widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.

What is the workflow of the adapter?

The adapter is also referred to as an external power supply (switching power supply), which is a power supply transformer for small portable electronic devices and electronic devices. because the supply voltage used in the household is 220 Volt and the supply voltage required by common electronic products is generally about 5 Volt to 20 Volt.

Therefore, the role of adapter is very important (module power supply), especially if you are traveling to countries like the United States and the voltage differs from that in China, you will need a 220-V to 110-V transformer.

What is the principle of the adapter?

The adapter is a power supply conversion device mainly used for small electronic devices and electronic devices. It generally consists of a housing, a power transformer and a rectifier circuit. It works like this:

1. Convert 220-V AC voltage to low voltage AC voltage via a reducer transformer.

2.When using 4-diodes, the unidirectional conductivity of the diodes is used to convert the alternating current to direct current (the size is changed).

3.Use capacitive filtering to convert the DC current of different size into a constant DC current.

What is the function of an adapter?

AC adapters convert 120-volt AC current from your wall outlet into a lower voltage DC source for your electronic devices. They do this in two steps by first scaling the voltage and then converting the alternating current into direct current.

Current voltage

AC adapters use a small transformer to reduce the 120-volts on the wall to a voltage in the range of 6-18 volts. The transformer consists of two coils scattered around an iron core. According to the laws of electromagnetism, the ratio of the number of turns in one wire to the number of turns in the other wire is equal to the ratio of the voltages in the two wires.

Correction

After converting the power supply to the desired voltage level, the adapter uses a device called a rectifier to convert the AC voltage to DC voltage. Rectifiers use a combination of diodes and unidirectional electronic components to generate a constant DC current from alternating current.

Example

A 12-volt adapter performs the following steps. First, 120-volt alternating current enters from the wall into one end of a transformer whose input corresponds to each of the 1-coil windings at the output and induces 12-volt alternating current. Next, the alternating current is output via a series of diodes to 12-volt direct current to charge your laptop, phone or mobile phone.
