Transformer is the use of the principle of electromagnetic induction to change the ac voltage of the device, main component is the primary coil, secondary coil and iron core.
Transformer is the use of the principle of electromagnetic induction to change the ac voltage of the device, main component is the primary coil, secondary coil and iron core. Main functions: voltage change, current change, impedance transformation, isolation, voltage regulator (magnetic saturation transformer), etc. According to use can be divided into: power transformer and special transformer (electric furnace change, rectifier, power frequency transformer, voltage regulator, mining, audio transformers, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.). T is commonly used as a serial number at the beginning of the circuit symbol.
Transformer is composed of iron core and the coil, coil, there are two or more than two windings, which connect power winding is called primary coil and the rest of the winding is called secondary coil. It can transform ac voltage, current and impedance. The simplest core transformer iron core made of a soft magnetic material and on the core set of two number of turns of the coil.
