<p>The present invention is to solve a problem of traditional proximity detection (PD) circuit and to provide an onboard battery charger (OBC) including a contact determination device of a vehicle charging gun capable of being strong on external electromagnetic interference. According to the contact determination device of the vehicle charging gun which is strong on an external electromagnetic interference signal and the OBC by the present invention, an error in which an MCU misunderstands voltage as a charging mode less than or equal to 3V through the external electromagnetic interference and the start of a vehicle is stopped and can be removed in spite of not having contact with a non-charging mode like the charging gun. The contact determination device of the vehicle charging gun comprises a power stabilization unit and a filtering unit.</p> |
