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.
