Abstract:
1. An engine driven inverter controlled generator set comprising: a power supply unit that uses a generator driven by an engine as a power supply to output a DC voltage; an inverter device that converts the output voltage of said power supply unit into an AC voltage; and an engine rotational speed control unit that controls a rotational speed of said engine so as to converge the rotational speed to a target rotational speed suitable for a load applied to said inverter device, wherein said engine rotational speed control unit is comprised so that a settling time necessary to converge the rotational speed to said target rotational speed when a detected load applied to said inverter is equal to or less than a set value is longer than a settling time necessary to converge the rotational speed to said target rotational speed when a detected load applied to said inverter is more than a set value.
