Abstract
PURPOSE: To reduce extremely the variation in voltage due to the impedance of line by detecting output current and then by controlling output voltage according to the detected output current.
CONSTITUTION: The deviation between the voltage detected through the voltage dividers R1 to R3 for the both end voltage of the load RL and the reference voltage VREF2 is applied to the base of the control transistor Q through the amplifying circuit A in order to stabilize the voltage supplied from the DC power source E to the load RL. The load current is detected through the resistor R5, and then the reference voltage is raised by an amount corresponding to voltage at which voltage drop is caused on feeder line due to the load current. Thus, stable voltage can be supplied to load even in case where feeder line is longer.
