Provided is a leakage current braking apparatus for an electric vehicle charger capable of performing self-diagnosis in real time in the electric vehicle charger. The leakage current braking apparatus comprises: a plurality of switches connected respectively to a current transfer line and a feedback transfer line between an external power source and a load; a diagnostic unit connected to a diagnostic line so as to output diagnostic current; an earth leakage sensor arranged to encompass the current transfer line, the feedback transfer line, and the diagnostic line, and sensing leakage current therefrom; and a control unit controlling opening/closing operations of the plurality of switches according to a comparison result between the leakage current and a reference value so as to control the connection between the external power source and the load.

    전기자동차 충전기에서 실시간으로 자가진단을 수행할 수 있는 전기자동차 충전기의 누전차단장치가 제공된다. 누전차단장치는, 외부전원과 부하 사이의 전류전송라인 및 피드백전송라인에 각각 연결된 다수의 스위치, 진단라인에 연결되어 진단전류를 출력하는 진단부, 전류전송라인, 피드백전송라인 및 진단라인을 둘러싸며 배치되고, 이들로부터 누설전류를 감지하는 누전센서 및 누설전류와 기준값의 비교 결과에 따라 다수의 스위치의 개폐동작을 제어하여 외부전원과 부하의 연결을 제어하는 제어부를 포함한다.
