<p>PURPOSE:To stabilize the output frequency by controlling the operation of an actuator for driving a throttle valve in response to the rotating speed of an engine and the output current of an engine generator. CONSTITUTION:A rotating speed detector 4 detects the frequency of an igniting pulse, and outputs the frequency detection signal through an F/V converter 8. A current value detector 5 forms and produces an output current from the output system of an engine generator by a current transformer 9, and outputs it through a rectifier 10. A controller 6 outputs an opening signal of a throttle valve in response to the analog detection signal of a rotating speed detector 4 and a current value detector 5. Thus, the stability of the output frequency of the generator can be improved.</p> |
