Abstract

It becomes possible to succeed in restarting a power supply unit. A power supply circuit includes the power supply unit which supplies DC power to a CPU, a switch which operates to cause a short-circuit to occur between a DC power supply and an input terminal of the power supply unit or to open a connection between the DC power supply and the input terminal of the power supply unit, a temperature measurement unit which measures a temperature and a processor which controls the switch to open the connection in a case of deciding that the DC power is not supplied to the CPU even when controlling the switch to cause the short-circuit to occur and controls the switch to cause the short-circuit to occur after a predetermined time elapses after controlling the switch to open the connection. The predetermined time is set on the basis of the temperature that the temperature measurement unit measures.
