Applications:

  1. Used in both Synchronous motors and induction motors.
  2. Used in electrical apparatus testing labs since the voltage can be smoothly and continuously varied.
  3. They find application as boosters in AC feeders to increase the voltage levels.

What function does a capacitor serve in an auto transformer?

An autotransformer does not normally use any capacitors as it is a transformer with one winding and the lower voltage is taken from a tap part-way up the winding. A capacitor could be added if there is a concern about the power factor presented by the autotransformer to the supply.


What is single phase autotransformer?

An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.


How many windings does a auto-transformer have?

A true autotransformer consists of one, tapped, winding. For a step-down transformer, part of the winding is in series with the supply and the other part is common to both the supply and the load. For a step-up autotransformer, part of the winding is in series with the load, while the other part is common to both supply and load.But you can also use a mutual transformer as an autotransformer, by connecting the two windings in series and, then, described as above.


Why a two winding transformer is used instead of single winding transformer?

You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
