Abstract
In a feed control apparatus that controls a feed state for an inductive load by controlling the opening and closing of a load opening and closing element connected in series to the inductive load, a free-wheeling circuit element employing a field effect transistor is connected in parallel to the inductive load so that a capacitor is charged by opening the free-wheeling circuit element when the load opening and closing element is closed and the free-wheeling circuit element is closed by charges charged to the capacitor when the load opening and closing element is opened. A connection is made in polarity in which a closed-circuit conduction direction in the free-wheeling circuit element is the same as a conduction direction in an internal parasitic diode of the free-wheeling circuit element, and the free-wheeling circuit element conducts backward by a small-capacity capacitor. Consequently, a voltage drop and a temperature rise are reduced.
