ABSTRACT:
A control apparatus includes a plurality of load circuits, a power supply wiring line that connects the load circuits to a DC power supply in common, and a counter electromotive force detecting unit that detects counter electromotive force generated on the power supply wiring line. Each of the load circuits includes a load, a semiconductor switch configured to turn ON/OFF the load for protecting the corresponding load circuit, and a current detecting unit that detects an abnormal increase of a load current flowing through the corresponding load circuit. When the current detecting unit detects an abnormal increase of the load current and the counter electromotive force detecting unit detects that an occurrence of the counter electromotive force which exceeds a predetermined threshold value, the semiconductor switch corresponding to the load circuit is cut off.
