A transformer transfers electric power from one circuit to another circuit without change in frequency. It contains primary and secondary winding. Primary winding is connected to main supply and secondary to required circuit.

Transformer is basically of three types:


1.Core Type
2.Shell Type
3.Toroidal
In core type windings surround a part of core where as in shell type core surrounds windings. In Core type there are two main types namely E-I type and U-T type. ei core transformer.

Classification of Transformer



Classified according to the operating frequency:
Power frequency (low-frequency) transformer, frequency 50HZ or 60HZ;
IF transformer, its operating frequency of 400 ~ 1000HZ;
Audio transformer, its operating frequency 20HZ ~ 20KHZ
Super audio transformer, its operating frequency 20KHZ generally does not exceed more than 100KHZ
High-frequency transformer, frequency 20HZ ~ 100KHZ

EI 

transformer

EI transformer is one of electronic transformer in accordance with the core shape to define, because the EI transformer core type sheet by the "E" and "I" type sheet stack up, so called EI transformer. EI transformer-frequency (low- frequency) transformer (50HZ or 60HZ), power transformer, some audio transformers of EI, such as stereo use.

The EI transformer in accordance with the size classification, general category is classified according to the silicon steel length. Example, commonly used EI-19, EI-28, EI-35, EI-41, EI-48, EI-57, EI-66, EI-76.2, EI-86, EI-96, EI-114 and so on. Wherein 28, 35, 41 these refer to the length of the laminations. The detailed classification but also consider the total stack thickness of silicon steel, some transformer above standard EI-48 * 20, this 20 refers to the silicon steel sheet total stack thickness is 20mm, so the transformer EI-48, subdivision under EI-48 * 20.

Some places there are classified in accordance with the silicon steel homes mouth width.
