Claims (1)

  1. 교류전로에 흐르는 전류를 2차측으로 변성하도록 배치된 변류기와, 이 변류기의 2차측에 접속된 정류회로와, 이 정류회로의 직류측 사이에 접속된 개폐기와, 상기 정류회로의 직류측에 접속된 역류방지장치, 이 역류방지장치의 출력측에서 상기 개폐기오 병렬로 접속된 평활콘덴서 및 이 평활콘덴서와 병렬로 접속되고, 상기 평활콘덴서의 접압이 소정치보다 커지면 상기 역류방지창지의 입력측에 접속되어 있는 상기 개폐기의 페로기간의 비율이 증가하도록 상기 개폐기를 제어하는 수단을 포함하는 제어전원을 구비하고, 소정치 이상의 불필요한 에너지가 상기 평활콘덴서에 흐르지 않도록 변류기 2차전류를 바이패스시키는 것을 특징으로 하는 과전류 보호장치.
