Abstract
A power supply circuit includes a power supply which supplies DC power to a load, a switch which is selectively operable to (i) cause a short-circuit to occur between a DC power supply and an input terminal of the power supply and (ii) open a connection between the DC power supply and the input terminal of the power supply, a sensor which measures a temperature and a processor configured to control the switch to open the connection in response to a decision that the DC power is not being supplied to the load even when the switch is being controlled to cause the short-circuit to occur, and control the switch to cause the short-circuit to occur after a predetermined time elapses after controlling the switch to open the connection in response to the decision. The predetermined time is set based on the temperature measured by the sensor.
