<P>PROBLEM TO BE SOLVED: To accelerate the evaporation of moisture produced on the surface of a component or the like constructing a power circuit by a moisture condensing phenomenon. <P>SOLUTION: The power supply device includes: the power circuit that supplies power to a motor for driving a vehicle; a fixing member by which the power circuit is fixed; a resistance element that is installed on the fixing member and one of whose terminals is connected to one of the two output terminals of the power circuit; a switch one of whose terminals is connected to the other terminal of the resistance element and whose terminal not connected to the resistance element is connected to the other of the two output terminals of the power circuit; a control unit that controls the switch; and a moisture detector that is installed on the fixing member and supplies the control unit with information indicating whether or not moisture has been detected. When the control unit is supplied with information indicating that moisture has been detected from the moisture detector, it brings the switch into conduction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
