ABSTRACT:
The common winding of an autotransformer is formed in two sections connected electrically in parallel and one section overlying the other. One section is wound clockwise and the other is wound counterclockwise. This reduces the voltage difference between adjacent layers of the two sections, permits the use of a smaller wire, and results in cooler and more efficient operation.
