please explain auto stab.the output of constant voltage transformer is 140v. scr fullwave ac switch with snubber circuit in series with 30v cvt output connected across 140v cvt o/p. a inductor(20mh) and capacitor(90 µ farad 550v) in series connected across 140 cvt o/p. scrs are triggered by pulse trans former. the o/p of cvt 140 fed through another two snubber circuit through center tap transformer across series transformer. my doubt is how the error voltage correction takes place. please explain autostab
