Abstract: An inverter power generator includes a current controller 14a setting a current limit ratio according to a rotation speed of a synchronous motor 13 and controls a converter current according to the current limit ratio. The current controller sets the current limit ratio to 70% if the synchronous motor is at a rotational speed equal to an idle speed of an engine 11. Until the rotational speed of the synchronous motor reaches a rated speed, the output current limiter linearly increases the current limit ratio up to 100%. With this, the rotational speed of the engine becomes reasonably increasable even if a sudden load increase occurs when the engine is operating at low speed.
