Power Supply Transformer Charger

What is the function of a transformer? As the name suggests, the transformer of course has the role of voltage, in addition he also has the role of transforming impedance, current and isolation circuits, is widely used in the power system. In general, the T beginning of the number is often used to do the equipment circuit symbols, such as T202, T05 and so on. There are many types of transformers, according to different ways of classification to divide, there are many different kinds of transformers, the role is not the same.

Transformer is the use of the principle of electromagnetic induction to change the AC voltage device, the main components are the primary coil, secondary coil and iron core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer) and so on. According to the use can be divided into: power transformers and special transformers (furnace transformer, rectifier transformer, frequency test transformer, regulator, mining transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.)

There are usually 3 ways to categorize transformers, the first is divided according to the number of power supply phases, the second is divided according to the cooling method, and the third is divided according to the frequency of work, as follows:

The first way of division: according to the number of power supply phases can be divided into single-phase transformers, three-phase transformers, multi-phase transformers.

The second can be divided according to the cooling method: dry-type transformers, oil-immersed transformers. The former is often a smaller capacity transformer, usually used for local lighting and other places, it is cooled by air convection to make it cool; the latter is generally used for large environment lighting and other places, the use of oil for cooling, self-cooling.

The third kind can be divided into the following four kinds according to the working frequency:
1. Pulse transformer: It is usually found in pulse circuits, such as the line output transformer in our TV sets at home is 1 of them.

2. low-frequency transformers: transforming voltage or impedance matching components, mainly audio transformers and power transformers. 3. medium-frequency transformers: also known as medium-frequency transformers.

3. medium frequency transformer: also known as the middle week, not only has the characteristics of low-frequency transformer, but also has the characteristics of resonance at a fixed frequency. It is used in a wide range of applications, including, for example, radio, television intermediate frequency transformer.

4. High-frequency transformer: there are also many fields of use, such as the magnetic antenna in the radio, the antenna impedance matcher in the TV set, and so on.
