Welcome to the Transformers!


A transformer is a passive electrical device that transfers electrical energy between two or more circuits. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across a second coil wound around the same core. Electrical energy can be transferred between the two coils, without a metallic connection between the two circuits.


There are a lot of different transformer types, all with their own applications, characteristics and construction. This page lists the different transformer types which are described on apogee.
