POWER CONVERSION DEVICE

摘要

To effectively suppress radiation and mixture of noise superimposed on a power line into a connection detection line. A power conversion device includes: a connector 200 having a wiring line 210 which transmits DC power; and a housing 101 in which the connector is arranged. The connector has a connection detection wiring line 220 which detects whether the connector is connected with an external circuit. An opening part 120 which connects with the connector is formed in the housing. An annular core 500 formed of a magnetic substance is inserted through the opening part. The annular core is an annular member formed with a through-hole. The wiring line and the connection detection wiring line are introduced into an inside of the housing through the through-hole of the annular core.
