ることを特徴とする直流電源供給回路。[Scope of claim for utility model registration] Supplying DC power to a load using a transmission line,
The load end voltage value is compared with the set load end voltage setting value, and if the load end voltage setting value is smaller or larger than the load end voltage, the load end voltage is set by a predetermined voltage amount at a fixed time rate. It is subtracted from the value and added to the load end voltage setting value, and when the load end voltage value and the load end voltage setting value are equal, the result of the addition/subtraction at that time is retained and the output voltage corresponding to the addition/subtraction result is sent to the transmission line. In a DC power supply circuit, a current fluctuation detector constantly monitors the load current value, calculates the difference from a predetermined load current value, and outputs a detection signal when this value exceeds a predetermined threshold. A DC power supply circuit comprising: a control means for replacing the addition/subtraction result with a load end voltage setting value when the detection signal is input.
