ABSTRACT:
An input power stabilizing circuit, adapted to be disposed between a DC power source and a load to which DC power from the source is to be supplied. Voltage on a capacitor in the input power stabilizing circuit is prevented as much as possible from causing reverse current to flow when the DC power source develops a short circuit momentarily. A current detecting unit detects reverse current from the capacitor in an input power supply line, and a current interrupting unit interrupts a current line connecting the load with the DC power source. When reverse current flow is detected, the current line is interrupted by the current detecting unit and the current interrupting unit. The reverse current from the capacitor is held to a minimum value in the input power stabilizing circuit.
