description The invention belongs to the technical field of alternating current and direct current measurement, and particularly relates to a method and device for processing direct current side current test data of a three-phase PWM converter, and the method comprises the steps: obtaining the direct current test data, measured by a Rogowski coil current probe, of the direct current side of the three-phase PWM converter; acquiring alternating current test data of any phase of the alternating current side of the three-phase PWM converter; calibrating the direct current test data according to the alternating current test data, then performing correctness judgment on the calibrated direct current test data, and if the judgment result is wrong, calibrating the direct current test data again; and if the judgment result is correct, obtaining the calibrated direct current test data. The three-phase PWM converter direct-current side alternating-current component test is realized, the direct-current component is further reconstru
