Inverter generator |
摘要 |
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. |

1. An inverter generator used in combination with a motor and an ECU generating a pulse at each predetermined rotation angle of the motor, the inverter generator comprising:
an electric generator driven by the motor configured to generate alternating current electric power; a circuit constructed and arranged to estimate an initial electrical angle of alternating voltage of the alternating current electric power from the pulse and calculate a phase shift angle from a difference of estimated d′-q′ axes from d-q axes of the alternating voltage of the alternating current electric power to estimate a continuous electrical angle of the alternating voltage of the alternating current electric power, the circuit being electrically connected with the ECU; a converter configured to convert the alternating current electric power into direct current electric power under d-q control based on the phase shift angle, the converter electrically connected with the electric generator and the circuit; an inverter configured to convert the direct current electric power into alternating current output electric power, the inverter electrically connected with the converter; and a shift drivingly coupling the motor with the electric generator so as to adjust a rising edge of the pulse with a zero-cross point of the alternating voltage of the alternating current electric power. |
