The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on. According to the application, it can be divided into: power transformer and special transformer (electric furnace change, rectification change, power frequency test transformer, voltage regulator, mine change, audio transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer , reactors, transformers, etc.).
