1. A power supply control device that controls power supply to a load via a switch, the power supply control device comprising:
a switching unit configured to switch on or off the switch; and
a determination unit configured to, if the switching unit switches the switch from off to on, determine power supply control conditions regarding control of power supply to the load, based on a waveform value regarding a current waveform of a current that flows through the load;
wherein the switching unit keeps the switch off for a certain time period after keeping the switch on for a certain time period, and
the determination unit determines the power supply control conditions based on a waveform value of the current waveform in a time period from when the switching unit starts to keep the switch on to when the switching unit ends keeping the switch off.
