The first preset value P1 is equal to or less than the lowest value, out of the upper limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work. The second preset value P2 is more than or equal to the highest value, out of the lower limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work.
