Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
Rectifiers turn A/C into D/C, but transformers can only run on A/C.
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
Transformer is a electric device which it can be used for to transfer the ac current one circuit to another i.e. To reduces voltage and without frequency changing. Many types of transformer available in various purpose i.e. Stepup transformer, stepdowntransformer ,autotransformer ,,,,,,,etc answered by arivukkarasu.a
yes we can place auto transformer in place of original transformer
why should we use pulse transformer rather than ordinary transformer
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
A chopper transformer is a kind of transformer used in an switching power supply.The primary input voltage of it is a Direct current (D.C) unlike any other ordinary step down transformer which uses an Alternating Current (A.C).Chopper transformer uses a switching transistor to produce a secondary voltage..

It's a transformer that operates with AC current in and out. It's an ordinary transformer, with the term "static" used to differentiate it from rotating transformers, such as motor-generator sets.
