<p>PROBLEM TO BE SOLVED: To provide an engine-generator control method and its device which control the aperture of an engine throttle, using a microcontroller to PWM- control an output inverter in common, without requiring an external circuit. SOLUTION: The output of a generator 11 is controlled by an inverter 13 for output, based on the operation of the PWM width of a microcontroller 14, while an operation and control means 18 performs the control of an engine 10, too. The operation and control means 18 supplies a driver circuit 16 directly with an operated value after converting it into form suitable for drive-processing the driver circuit 16 for a stepping motor 16. The microcontroller 14 is equipped with a mean for switching PWM operation, throttle aperture operation, and drive processing, and this is one being constituted so as to switch it compulsively into PWM operation, even if the throttle has not completed its shifting to the objective position, when a certain time passes for throttle aperture operation and drive processing.</p> |
