ABSTRACT:
The present invention provides a control apparatus for detecting an early stage short circuit between the terminals of an electrolytic capacitor, and detecting a short circuit between a load that is connected in parallel to the electrolytic capacitor, the apparatus performing appropriate processing before an adverse effect is inflicted on peripheral equipment. In the control apparatus, microcomputers switch on a second relay; an electrolytic capacitor is gradually charged via a current-limiting resistor; a first voltage detection control for detecting a voltage between terminals of the electrolytic capacitor is performed when a first set time period has elapsed after the second relay has been switched on; and a second voltage detection control for detecting a voltage between the terminals of the electrolytic capacitor is performed when a second set time period, which is longer than the first set time period, has elapsed after the second relay has been switched on.
