Japan, Feb. 27 -- TMEIC CORP has got intellectual property rights for 'POWER CONVERSION DEVICE.' Other related details are as follows:
Application Number: JP,2023-035899
Category (FI): H02M7/155@G,H02M7/12@H
Stage: PROBLEM TO BE SOLVED: To provide a power conversion device that is capable of detecting the occurrence of failures of a plurality of switching elements having a predetermined resistance value.SOLUTION: A power conversion device comprises: a main circuit unit that performs conversion of electric power by switching a plurality of switch parts; and a control device that controls the conversion of electric power by the main circuit part. Each of the plurality of switch parts includes a plurality of switching elements connected in series. The control device identifies a switch part containing a switching element in which a failure with a predetermined resistance value has occurred, by detecting that a failure with the predetermined resistance value is occurring in any of the plurality of switching elements if a period representing that a forward voltage of any of a plurality of forward voltage signals is being applied overlaps with a period representing that a reverse voltage of any of a plurality of reverse voltage signals is being applied.SELECTED DRAWING: Figure 1 (Grant)
