A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits.
I thought that was the definition of transformer, two windings that don't touch but share flux. You could convert from 220 volt mains to 110 volts by having a center-tapped winding or you could have two distinct windings, one for 220 volts and one for 110 volts.
