<p>In a power converting apparatus in which two three-phase converters (1, 2) are operated in parallel to one another, the three-phase converters (1, 2) are controlled by using d-axis and q-axis voltage commands. DC current sensors (26, 27) detect individual output DC currents (26a, 27a) of the three-phase converters (1, 2), and a d-axis voltage command (vdr) for each of the three-phase converters (1, 2) is corrected in a manner that reduces a difference between the output DC currents (26a, 27a). In this way, an output imbalance between the two three-phase converters (1, 2) is corrected while decreasing limitations on arrangement of the DC current sensors (26, 27).</p> |
