摘要： PROBLEM TO BE SOLVED: To provide an inverter which can detect or control the fundamental wave components of output voltage accurately. SOLUTION: Insulating amplifiers InsOP1 and InsOP2 separate the grounds of input and output and amplify the line voltage of three-phase AC. A low-pass filter 311 takes out the fundamental wave components of the output voltage of the insulating amplifiers InsOP1 and InsOP2. An A/D converter 318 performs the A/D conversion of the fundamental wave components. An integrator 313 computes a phase value by integrating the frequency command signal of a tested inverter. A correction signal generator 314 adds the signal of the reverse property of a low-pass filter 311 to the phase value by means of an adder 315, and gets the reference phase value θ of a three-phase/two-phase converter 312. The three-phase/two-phase converter 312 changes the coordinate of the fundamental wave components of the three-phase AC voltage, on the basis of the phase value θ thereby converting it into two-phase voltage, and a multiplier 316 multiplies the two-phase voltage by the signal from the correction signal generator 314, thereby correcting the properties.
