<p>PURPOSE:To prevent the sudden fluctuation of engine rotating speed, by gradually increasing or decreasing the power sent from a generator to an electric load in changing the operating state and stopping state of the electric load. CONSTITUTION:Power supply control means 9 and 9' are used for duty control of electric load, which are composed of triangular wave generation circuits 9a and 9'a, delay circuits 9b and 9'b to raise or reduce the voltage gradually when the step input is received, comparators 9c and 9'c and power transistors 9d and 9'd. When the first changeover switch 2 for electric load or the second changeover switch 2' for electric load is changed over from OFF to ON, gradually increasing voltage is applied to the electric load. On the other, when the changeover switches 2 and 2' are changed over from ON to OFF, the voltage applied gradually decreases.</p> |
