The Classification of electronic transformers

In this article, we will introduce the classification of electronic transformers

1. Classification by operating frequency:

Power frequency transformer: operating frequency is 50Hz or 60Hz

Intermediate frequency transformer: operating frequency is 400Hz or 1KHz

Audio transformer: operating frequency is 20Hz or 20KHz

Super audio transformer: more than 20KHz, not more than 100KHz

High-frequency transformer: The operating frequency is usually above KHz to hundreds of KHz.

2. Classification by use:

Power transformer: A transformer used to provide the power required by electronic devices

Audio transformers: transformers used in audio amplification circuits and audio equipment

Pulse transformer: A transformer working in a pulse circuit, and its waveform is generally a unipolar rectangular pulse wave

Special transformer: transformer with a special function, such as parametric transformer, voltage stabilized transformer, super isolation transformer, transmission
Line transformers, magnetic leakage transformers

Switching power transformer: Used in switching power supply circuits for transformers

Communication transformer: a transformer used for DC isolation and filtering in communication networks
