In an inverter generator having a generator unit driven by an internal combustion engine, an inverter that inverts converted direct current to alternating current with switching elements to supply to an electrical load, an inverter driver that comprises an microcomputer and drives the switching elements with a PWM signal to make the alternating current of a predetermined frequency, an ignition unit that ignites the engine, and an ignition controller that controls operation of the ignition unit, the engine speed is detected and it is determined whether the engine is under over revolution condition based on the detected engine speed. The inverter driver sends a command to the ignition controller to terminate the ignition to stop the engine, when the engine is under the over revolution condition, thereby enabling to prevent the engine from experiencing over revolution repeatedly.
