Abstract
A power supply system includes a high-potential side output end and a low-potential side output end that output the power; an input end to which a positive voltage is applied from a DC power source; a power storage element including a positive terminal connected to the high-potential side output end and a negative terminal connected to the low-potential side output end; a diode including a cathode and an anode, the anode being connected to the input end; a power source line connected between the cathode and the positive terminal; and a switch, connected to the diode in parallel, that turns on when a current value of current flowing in the power source line from the cathode toward the positive terminal is greater than or equal to a positive threshold, and turns off when the current value is less than the threshold.
Claims4
A power supply system that supplies power to a load, the system comprising:
- a high-potential side output end and a low-potential side output end that output the power;
- an input end to which a positive voltage is applied from a DC power source;
- a power storage element including a positive terminal connected to the high-potential side output end and a negative terminal connected to the low-potential side output end;
- a diode including a cathode and an anode, the anode being connected to the input end;
- a power source line connected between the cathode and the positive terminal;
- and
- a switch, connected to the diode in parallel, that turns on when a current value of current flowing in the power source line from the cathode toward the positive terminal is greater than or equal to a positive threshold, and turns off when the current value is less than the threshold.
