    摘要: In an inverter generator, having a generator unit driven by an internal combustion engine whose throttle valve is moved by an actuator and generates alternating current, and an inverter that converts converted direct current to alternating current with switching elements to supply to an electrical load, voltage and current supplied to the electrical load is detected, a power factor is calculated from the detected voltage and the current, a power of the load is estimated from the detected current and the calculated power factor. Then a desired speed of the engine is determined based on the estimated power of the load, and the actuator is controlled such that an engine speed becomes equal to the desired engine speed, thereby improving the response of engine speed control.
