Abstract: Aiming at improving performance of the AC voltagestabilized source, conquering disadvantage of mechanic abrade, big noise and long reactive time for the mechanic adjustment AC voltagestabilized source, and adapting the occasion of nobody is on duty, a single chip microcomputer(SCM) was used as controller, some thyristors were used as noncontact switches, and compensated technique was used, the disadvantage upwards was overcomed completely. The intelligent control and communicating interface were introduced, the automatic coming back, automatic examining, remote control, remote measure, remote signal were realized. The test results indicate that the performance of high power intelligent AC voltagestabilized source is excellent, all target suits for the design and it is the same with occasion of nobody on duty.
