Abstract

PURPOSE: To keep the voltage of one of a plurality of loads constant when the others are fluctuating, by using the terminal voltage of a resistor to compensate the fall in an output voltage due to the increase in the load.
CONSTITUTION: An oscillating voltage is applied from an oscillation circuit to an arithmetic amplifier B, the output of which is amplified by transistors Q1, Q2 to supply power from the secondary side of a transformer T2 to loads Za, Zb. A reference voltage from a Zener diode D1 and a voltage on a point (b) of a resistor R5 are applied to another arithmetic amplifier A, the output of which controls the oscillating voltage applied to the former arithmetic amplifier B. When the load Za becomes heavier, the terminal voltage of the resistor R5 rises and the point (b) deepens in the negative direction and a non-inverted input voltage to the operational amplifier A rises. As a result, an output voltage is raised to compensate the fall in the voltage. The voltage applied to the load Zb is thus kept constant.
