Abstract

프로젝션 TV의 컨버젼스 전원 공급에서 컨버젼스 회로의 로드 변화에 따른 출력전원 전압의 변동을 검출하여 이상전원 전압시 전원전압을 차단시키고 전원부 동작을 멈추게 하여 컨버젼스 회로 및 전원회로를 보호하는 회로를 제공하기 위해 전원 출력전압의 감소(전류증가) 분을 검출하고, 전원 출력전압의 증가(전류감소)분을 검출하여 상기 검출 출력에 따라 이상전원발생시 전원전압의 공급을 차단시키고 전원부의 동작을 정지시켜 컨버젼스 및 전원회로를 보호하도록 되어 있다.In order to provide a circuit that protects the converged circuit and the power circuit by detecting the change of the output power voltage according to the load change of the converged circuit in the converged power supply of the projection TV, cutting off the power voltage during the abnormal power voltage and stopping the power supply. Detects the decrease of the output voltage (current increase), detects the increase of the power output voltage (current decrease), cuts off the supply of power voltage when the abnormal power is generated according to the detection output, and stops the operation of the power supply unit for convergence It is intended to protect the circuit.
