Abstract
이 발명은 PWM 회로를 구비한 전원공급회로에 관한 것으로서, 전원공급 입력단에 과전압 검출회로를 구비시켜, 과전압이 발생되면 이를 감지하여 실리콘 정류 과전압 발생 동안에는 PWM 회로의 동작을 중지시켜 과전압을 제거하는 것을 특징으로 한다.The present invention relates to a power supply circuit having a PWM circuit, comprising an overvoltage detection circuit at a power supply input terminal, detecting an overvoltage when the overvoltage occurs, and stopping the operation of the PWM circuit during the silicon rectification overvoltage generation to remove the overvoltage. It features.
