| 摘要 |
A power supply system is disclosed, including a first plurality of power supply units configured to supply working voltages from a battery to a second plurality of loads, a large-capacitance capacitor configured to charge electric charges from the battery, a third plurality of switching means for connecting the large-capacitance capacitor to the second plurality of loads selectively, control means for switching the third plurality of switching means corresponding to the load presently driven, and discharge means, in a case where the output voltage of the large-capacitance capacitor is higher than the operating voltage of the second load when the capacitor is switched from a first load to a second load, for discharging the charges stored in the capacitor according to the monitoring result by a voltage monitoring means so that the voltage of the capacitor decreases to the operating voltage.
