The invention includes first and second transistor switch groups in each of which arms are connected in parallel, and sense resistors for detecting a drain current are connected to the first and second transistor switch groups, and a first drive circuit group and the second drive circuit group include means for monitoring a sense current flowing through the sense resistors and a plurality of delay circuits. Further, rising of the plurality of transistor switch groups is controlled by controlling activation and non-activation of the plurality of delay circuits on the basis of a magnitude of the sense current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device","description":"An uneven return current is prevented and increase in a loss is suppressed in a power conversion apparatus at the time of inverter operation.
