    Well a variac is just an autotransformer with a wiper for the output voltage tap. The wiper typically can make contact to windings both below (lower voltage) and above (higher voltage) the input voltage tap. I googled transformer theory autotransformer, and got lots of hits. Here's one website with pretty good transformer info:
