Abstract
A generator having an electronic governor for controlling the speed of an engine to generate an output voltage from an alternator is disclosed. The generator includes an alternator coupled to an engine to generate an output voltage. The variable speed of the engine allows the alternator to generate a variable output voltage. An electronic governor monitors a time period between voltage benchmarks on the output voltage. The electronic governor compares the monitored time period to a reference time period and adjusts the position of the throttle based upon the comparison between the monitored time period and the reference time period. The reference time period is set based upon the desired output voltage frequency. In an alternate embodiment, the electronic governor senses the current draw from the alternator and adjusts the position of the throttle to prevent changes in the frequency of the output voltage.
