Has anybody used a Autoformer can tell me how it works

Its two sets of windings on the same transformer core, connected in series they can raise or lower voltage from input to output. Its a simple xfer that uses a complex or simple regulator to adjust the output voltage, usually raise it. If this is the case available current is decreased.
I've noted in NEC (national electric code) rules they are not approved for fixed RV applications due to higher than desired cause of fires. It works by inducing emf across a core of wire of many turns. The ratio of turns in to out will increase or decrease voltage out.
