What is a double-winding transformer?
The so-called double winding transformer means only two windings in the transformer. There are two windings (two coils) on a phase iron core, one is the primary winding, and the other is the secondary winding. The double winding transformer is a commonly used transformer product. The winding process of the transformer will have different requirements according to different usage occasions (different purposes). Its main functions are voltage transformation, impedance transformation, isolation, voltage stabilization, etc.
