Abstract

PURPOSE:To stabilize the AC output voltage vy permitting a control computer provided in the control system to also effect the AC output voltage control. CONSTITUTION:For stabilizing the source voltage for a system having a control computer such as a duplicator, the source voltage AC is coupled through a phase controller PC such as a triac for controlling the condution angle and then coupled through a transformer T to a full-wave rectifier REC for rectification, and the output therefrom is coupled to the control computor CUP for sampling the peak, which is held in an analog memory. The hold value in the analog memory is coupled to a voltage level discriminating circuit VD to produce a bit pattern corresponding to the hold voltage. This bit pattern is converted through the control computor into a pulse of a predetermined interval to control the conduction angle of the phase controller PC so as to stabilize the voltage supplied to the system.
