Abstract: A current control unit takes a deviation between a current command value and a current flowing through an inverter of a power conversion device, and controls the inverter based on the deviation. A harmonic sensing part receives input of an output current of an AC filter, and outputs a predetermined order harmonic of the input current in a direct current value form. A disturbance observer estimates the disturbance of the harmonic based on the output current and a coefficient defined as an inverse function of a transfer function from harmonic suppression current command value to filter output current detection value. A harmonic suppression control unit takes the deviation between the estimated harmonic disturbance and a disturbance command value that suppresses the disturbance, and calculates a harmonic suppression current command value. The harmonic suppression current command value is superimposed on the current command value of the current control unit.

Abstract: [Object] The present invention provides a space vector modulation method for an AC-AC direct conversion device, which can convert input and output waveforms into sine waves and reduce the number of times of switching at an inter-sector shift.[Means to Solve] A vector state in which a line voltage of multi-phase AC output is expanded onto a two-phase static αβ coordinates is defined. Simple harmonic oscillation vector axes of a sector where an output voltage command value vector Vo* exists are defined as an X axis and a Y axis. Maximum/middle/minimum vectors in each axis, a zero vector that is an intermediate voltage of a phase voltage, and one rotation vector that is present in the sector, are set as base vectors. A switching selection pattern formed by a combination of four vectors among these vectors, which satisfies predetermined conditions, is determined by a selection means 15. On the basis of power source voltage information and output current information, an inverse matrix operation for the four vectors is executed by a duty operation means 14, and a duty solution of the four vectors is determined, then the input and output waveforms are simultaneously converted into the sine waves by the determined duties.

Abstract: Disclosed is a current source inverter device which controls the power factor in an arbitrarily configurable manner without a magnetic pole position detector. The device is provided with a current source inverter; a motor supplied with alternating current power from the current source inverter; and a control means which detects the terminal voltage of the motor, calculates the motor's internal induced voltage and the motor current that flows in the motor based on the detected terminal voltage, and controls the current source inverter. The control means calculates the phase difference (θc) between the terminal voltage and the motor current, the phase difference (θx) between the motor current and the internal induced voltage, and the phase difference (θv) between the terminal voltage and the internal induced voltage. An adjustment angle (θα), which is the error in the phase difference between the motor current and the internal induced voltage when the set value of the phase difference (θx) is θy, is obtained from the conditional equation θα=θv−θy−θc.
