<p>PURPOSE:To prevent an engine from decreasing at the idling speed by controlling the power amount supplied to an electric load by a charging generator to the minimum limit at idling time. CONSTITUTION:When the rotating speed N of a generator is a set rotating speed N0 or higher, the output of a NAND gate becomes ''1'', and a transistor 23 becomes ON. Thus, a resistor 14 is shortcircuited, and a voltage detector is composed of resistors 15, 16. On the other hand, when the speed N of a generator is a set rotating speed N0 or lower and a field current IF is set value IF0 or lower, the output of a NAND gate becomes ''0'', and the transistor 23 becomes OFF. Thus, a voltage detector is composed of resistors 15, 16, 22, and the output voltage of the generator decreases. Thus, it can prevent an engine from decreasing at its idling speed.</p> |
