Abstract: An inverter device includes a voltage command value output unit that outputs a voltage command value, voltage sensors that detect output voltage from a switching circuit, a Fourier transform unit that performs frequency analysis on the output voltage detected by the respective voltage sensors, and a voltage correction value calculation unit that obtains harmonics with respect to a drive frequency of the switching circuit subjected to the frequency analysis by the Fourier transform unit and obtains a voltage correction coefficients for correcting the voltage command value so as to cancel the harmonics. The voltage correction value calculation unit calculates coefficients each for each degree of the harmonics and determines whether the coefficients converges when calculating the coefficients so as to obtain the voltage correction coefficients based on the coefficients which are determined to converge.

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.

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.

Abstract: An imaging device including an electronic shutter and a pixel array with color pixels with different characteristics of spectral sensitivity arranged. The pixel array part has at least one clear pixel, the plurality of color pixels including at least two of (i) a first color filter pixel having a peak of spectral sensitivity characteristics for red, (ii) a second color filter pixel having a peak for blue, and (iii) a third color filter pixel having a peak for green. The clear pixel has a high transmittance arranged in an oblique pixel array system at a given position of a given row and a given column with respect to the first color filter pixel, the second color filter pixel, and the third color filter pixel. An electronic shutter is separately driven for the at least one clear pixel and for the plurality of color filter pixels.

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.
