Abstract
The utility model relates to an auto-transformer of an adjustable transformer. The main member is composed of a transformer and at least a group of carbon brushes, wherein the transformer comprises at least a group of inner coil windings and at least a group of outer coil windings, and the coil number of the coil which is wound on an iron core of the outer coil windings is determined by previous chosen output voltage range. The surface of the outer coil is polished for being contacted with the carbon brushes so as to output a specific voltage value. The coil number of the coil which is wound on an iron core of the inner coil windings is determined by the output voltage range which is not chosen previously. The design of the auto-transformer can cause the adjustable transformer to elastically make the outer coil windings according to the previous chosen output voltage range.
