Abstract
Official abstract text for this publication.
An apparatus for diagnosing failure of an inverter includes switches coupled to three phases of A, B, and C, respectively. The apparatus also includes a measurer configured to measure each of the output currents of the three phases. The apparatus also includes a comparison processor configured to receive the output currents measured by the measurer and compare the received output currents with a set value. The apparatus also includes a failure determination processor configured to detect a switch having an output current equal to or smaller than the set value based on the comparison performed by the comparison processor to determine the switch as faulty. The failure determination processor is also configured to, upon detecting faulty switch, identify which phase switch is faulty to change the duty ratio of the switch determined to be faulty and to perform phase shift on switches not determined to be faulty.
