a simple and inexpensive way to correct problems that arise when a secondary voltage is difficult to obtain or a transformer you have is either too high or too low
a single, tapped inductor coil used to step up or step down voltage like a transformer, except without providing electrical isolation
a tapped winding transformer that changes the voltage available locally to the voltage required by a particular load
a transformer having part of its winding included in both the input and output circuit
a transformer that does not have a true secondary coil-- there is just one winding with part of it acting as the primary, and the other acting as the secondary
a transformer that uses a common winding for both the primary and secondary windings
A special type of power transformer, consisting of a single, continuous winding that is tapped on one side to provide either a step-up or step-down function.
A transformer used to step voltage up or down. Because its primary and secondary windings share common turns, it does not provide isolation.
A special type of single coil transformer in which the output voltage can be easily varied. The autotransformer is thus employed to adjust the primary voltage applied to the stepup transformer which produces the high voltage applied to the x-ray tube.
A type of transformer in which portions of the windings are shared by the primary and secondary circuits.
Transformer with at least part of the windings common to both the primary and secondary circuits, with very low losses. It may be used to change electric voltage from a generator to the higher voltage needed for efficient transmission over power lines. They can also be used to change a two-wire electrical supply to a three-wire system.
Transformer in which both primary and secondary coils have turns in common; step-up or step-down of voltage is accomplished by taps on common winding.
A transformer in which the primary and secondary are in a single winding.
An autotransformer is an electrical transformer with only one winding. The winding has at least three electrical connection points called taps. The voltage source is applied to two taps and the load is connected to two taps one of which is usually a common connection that is also connected to the source.
