What Is Power Transformer

A transformer is an electrical device used for electrical energy conversion, which converts alternating current of one voltage and current into alternating current of another voltage and current of the same frequency.

Transformers are used in almost all electronic products. The principle is simple, but depending on the application (different applications), the winding process of the transformer will have different requirements. The functions of the transformer mainly include: voltage conversion; impedance transformation; isolation; voltage regulation (magnetic saturation transformer), etc., and the core shape commonly used in transformers generally has E-type and C-type iron cores.
