[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformer is the basic equipment for power transmission and distribution, and is widely used in industry, agriculture, transportation, urban communities and other fields.
