Inverter controlled generator set |
摘要 |
An inverter controlled generator set including: 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 the power supply unit into an AC voltage; and a rotational speed control unit that controls a rotational speed of the engine so as to be kept at a target rotational speed suitable for a load applied to the inverter device, wherein the rotational speed control unit is comprised so that a settling time when the rotational speed of the engine is caused to converge to the target rotational speed in a state where the load is above a set value is longer than a settling time when the rotational speed is caused to converge to the target rotational speed in a state where the load is below the set value, in order to minimize an operation sound of the engine when the load is intermittently driven.
