Abstract

본 발명은 소비전력을 최소화하기 위한 절전형 전원회로 및 제어방법에 관한 것이다.The present invention relates to a power-saving power supply circuit and a control method for minimizing power consumption.

종래 전원제어회로는 핫샤시의 경우는 티브이의 내부, 외부의 동일한 그라운드에 의한 감전위험등으로 대형티브이의 경우에 부적합하며, 1차 및 2차측의 접지분리형인 콜드샤시의 경우는 감전위험등의 문제는 없으나 티브이의 내부와 외부의 그라운드분리를 위하여 1차와 2차가 분리된 릴레이스위치를 사용하게 됨에 따라 릴레이스위치를 구동하기 위한 스텐바이전원이 필요하므로 스텐바이시 전력손실의 문제점이 있었다.Conventional power supply control circuits are not suitable for large-sized systems due to the risk of electric shock due to the same ground inside and outside of TVs in the case of hot chassis, and in the case of cold chassis with ground separation type of primary and secondary sides. There is no problem, but as the primary and secondary relay switches are used to separate the ground inside and outside the TV, there is a problem of power loss during standby because a standby power source for driving the relay switch is required.

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 전원만을 온, 오프 제어하도록 하는 전원제어부를 구성하여, 전원스텐바이시는 반도체스위치를 온, 오프스위칭 제어하므로서 소비전력을 최소화시키고, 전원 온 시에는 SMPS트랜스를 이용하여 전력의 효율을 높이므로서 소비전력을 줄일 수 있도록 한 것으로 가전제품의 전원부에 적용한다.The present invention comprises a power supply control unit to control only the power supply on and off in order to solve such a conventional problem, the power standby is to minimize the power consumption by controlling the semiconductor switch on, off switching, The SMPS transformer is used to reduce power consumption by increasing power efficiency. It is applied to the power supply of home appliances.
