<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus calculating power consumption, without particularly providing a measuring means. <P>SOLUTION: A CPU 3 samples and accumulates an ON period of a switching signal given to a switching element S1 from a switching control circuit 2 and reads power consumption stored in a non-volatile memory 4, corresponding to an accumulation period so as to output power consumption. Thus, power consumption can be calculated without arranging the special means, and cost is prevented from becoming high. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
