What Is Transformer?

- Oct 24, 2018-

The transformer is composed of a core and a copper coil wire wound around the insulating bobbin. The insulated copper wire is wound around the plastic skeleton, and each skeleton needs to be wound and input and output two sets of coils. The middle of the coil is insulated with insulating paper. After winding, many core sheets are inserted in the middle of the plastic skeleton. This makes it possible to significantly increase the inductance of the coil. The transformer uses electromagnetic induction to transfer electrical energy from one of its windings to the other. The transformer has an important function in the circuit: coupling the AC signal to block the DC signal, and changing the voltage ratio of the input and output; using the transformer to make the impedance at both ends of the circuit well matched to obtain the maximum transmission signal power.
