Abstract

PURPOSE: To correct DC voltage automatically in order to prevent the variation of DC voltage even if there is a variation in the voltage of AC power source without feedback control.
CONSTITUTION: The phase control circuit consists of the synchronous signal generating circuits 21 to 23 to generate signal of different π/2 phases, the DC signal generating circuits 11 and 12 to generate signal proportional to the magnitude of AC voltage, the DC signal circuits 14 to 16 to generate a definite signal different in polarity from the DC signal of the circuits 11 and 12, the comparators 17 and 18 to compare the added signal of each DC signal with the signal of the synchronous signal generating circuits, and the pulse generating circuit 19 to generate a gate pulse for the control rectifying device 3 by the operation of the comparators. With the system, in case where AC power source voltage varied, the varied amount is corrected by adjusting the setting device 12 and DC voltage applied to the base of the transistor 19 is made constant, thus keeping the DC output voltage of rectifier constant.
