Abstract
A capacitor power supply unit includes detectors for detecting an output voltage of a capacitor group, which includes a plurality of capacitors, and a charge controller that sets a long-time time limit if the output voltage is lower than a set value, and sets a short-time time limit if it is higher than the set value, starts counting the time when the reaching signal is generated, and stops charging performed by the chargers after the time limit elapses.
