Claims (1)

  1. PWM 제어 IC(IC1), 스위칭트랜지스터(W1)와 주전력트랜스(T1)등을 포함한 SMPS 회로에 있어서, 상기 PWM 제어 IC(IC1)의 입력과 주전력트랜스(T1)측의 정류된 출력과의 사이에 마련된 과전류보호부(1)와 상기 스위칭트랜지스터(Q1)의 콜렉터, 에미터 사이에의 전류트랜스(T2)를 포함한 퀘환정류회로(2)로 되고, 이 퀘환정류회로(2)의 출력은 과전류보호부(1)의 비교기(IC2)로 인가되며 이는 주전력트랜스(T2)의 정류전원 출력측과의 전압과 비교되어 PWM 제어 IC(IC1)에 가해지는 구성을 특징으로 하는 전원기기의 과전류보호회로.
