Generally AC drives, assuming you are talking about controlling AC motor speed, are referred to as "variable-frequency drives" (VFD).

Lots of info on Google for "variable-frequency drive" and VFD.

A start: http://en.wikipedia.org/wiki/Variable-frequency_drive

Go to http://www.joliettech.com/ac_drives_principles_of_operatrion.htm

There is very good information regarding variable speed drives, both AC and DC.
