An inverter apparatus (10) is provided with first and second current detectors (4r, 4s) for detecting the current of two arbitrary phases (R, S) and further with first and second A/D converters (5r, 5s), and they are integrated into one unit. It furthermore stores, in a storage device (7), a compensation value for compensating for an unbalance between gains of the first current detector (4r) and the first A/D converter (5r), and gains of the second current (4s) detector and the second A/D converter (5s). By multiplying the detected current value of either one of the detected phases (R, S) by this compensation value, it equalizes the current feedback gains for both phases (R, S). |
