Transformer is to use the principle of electromagnetic induction to change the AC voltage of the device,the main component is the primary coil,secondary coil and core (core).In the electrical equipment and radio roads that are commonly used for lifting voltage and impedance matching.Security isolation.Its features are:voltage transform; current transformation,impedance transformation; isolation; Regulators (magnetic saturation transformer); auto-transformer; high-voltage transformer (dry type and oil-immersed),etc.
