<P>PROBLEM TO BE SOLVED: To improve current detection accuracy by detecting, with high reliability, the temperature of a shunt resistor that becomes the base of a resistance value. <P>SOLUTION: A temperature sensor 60 is disposed positionally correspondingly to the central part of a shunt resistor SR. Thus, the approximately average temperature of the shunt resistor SR can be detected while avoiding an eccentric temperature within temperature distribution in the shunt resistor SR. Thus, by detecting the temperature of the shunt resistor that becomes the base of a resistance value with high reliability, current detection accuracy can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
