If you dont get confused with the name (auto-transformer)
and its internal construction, it is same as normal
transforer as far as its working is concerned.

The consruction is little different. Primary and secondry
windings are physically same i.e. only one winding is
there. This winding has multiple taps. The winding between
common tap and one tap is Primary winding. The winding
between common tap and some other tap is Secondry
winding.
