A power converting apparatus includes a timing signal generator and a phase determination signal generator provided in an ON/OFF signal generating unit (8) as well as a detected current correction unit (9). On the basis of timing signals (ts1,...) and phase determination signals (ph1,...), the power converting apparatus determines detected current values and phases of the detected current values fed from a DC bus current sensor (3) at timings set in accordance with the timing signals and corrects the detected current values (idc1,...) for the individual phases obtained at the individual timings during PWM cycles to represent values which would be obtained at a reference timing (t0) to thereby reduce errors caused by differences in the current detecting timings for the individual phases. |
