This paper introduces a highly stablized general purpose AC power supply, which consists of tapped transformer,triacs and microcomputer.The diagrams of main circuit and driving circuit hardware and software are demonstrated.This AC power supply effectively solves the problem of triac circulating current while commutating.It makes AC voltage stabilization able to be realized when voltage is fluctuated and load is varied. The precision of AC output is ±1%.
