1. A power control device that performs power supply to each of a plurality of loads by a time-proportional control,
wherein a maximum load factor and a current value or a power value during ON-control are associated with each of the plurality of loads,
the power control device comprising an automatic power supply allocation unit that is programmed to perform:
a processing of calculating a combination of the loads wherein a total value of a current value or a power value during ON-control associated with each of the loads does not exceed a limiter value that specifies an upper limit to a total of a current value or a power value output to the plurality of loads;
a processing of setting a period wherein each load of the combination is simultaneously ON-controlled based on a minimum value among remaining output of the maximum load factor of each load of the combination and subtracting the period from a maximum load factor of each load of the combination; and
repeating each processing until all maximum load factors of each of the loads become zero to thereby automatically allocate a supply of power among the loads.
