  • Patent number: 8803345
    Abstract: An inverter generator includes a motor, an electric generator and an ECU generating a pulse at each predetermined rotation angle of the motor. Estimating means estimates an initial electrical angle of alternating voltage produced by the generator from the pulse and calculates a phase shift angle to estimate continuous electrical angle of the alternating voltage. A converter converts the alternating current electric power into direct current electric power under d-q control based on the phase shift angle. An inverter converts the direct current electric power into alternating current output electric power.

  • Patent number: 8786225
    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.

  • Patent number: 8624533
    Abstract: An inverter includes a voltage command generator generating a voltage command value according to an externally specified voltage value, a PWM signal generator generating a PWM signal according to the voltage command value and frequency command value, and a switching unit generating a three-phase AC power according to the PWM signal. The voltage command generator decreases the voltage command value if the output current increases, to prevent the rotation speed of a prime move from suddenly changing. If the output current exceeds a preset upper current threshold, the voltage command value is clamped at a preset minimum output voltage, thereby securing the minimum output voltage for an increase in the output current.
