Abstract

텔레비젼 수상기가 전원 오프(OFF) 상태일 경우, 리모콘으로부터 전원 온(ON) 신호가 인가되어질 때 텔레비젼 수상기를 가동하기 위한 구성요소를 제외한 모든 구성요소에 전원을 차단함으로써 텔레비젼 수상기의 전원 오프(OFF)시 전력소모를 최소화 할 수 있도록 된 텔레비전 수상기에 전원제어장치의 관한 것으로서, 텔레비젼 수상기에 있어서, 전원플러그로부터 입력되는 전원을 변압하여 대기전원부로 공급하는 제1트랜스포머와, 전원플러그로부터 입력되는 전원을 변압하여 주전원부로 공급하는 제2트랜스포머, 상기 전원플러그로부터 상기 제2 트랜스포머로 인가되는 전원을 스위칭하기 위한 스위치수단, 상기 제1트랜스포머로부터 공급되어진 전원을 근거로 텔레비전 수상기를 가동시키기 위한 일련의 장치에 소정의 대기전원을 공급하는 제1레귤레이터, 상기 제1트랜스포머로부터 공급되어진 전원을 근거로 후술되어질 래치단으로부터 출력되는 동작가능신호에 따라 후술되어질 제어수단에 동작전원을 공급하는 제2레귤레이터, 상기 제1레귤레이터로부터 공급된 전원을 근거로 리모콘으로부터 전원 온(ON)신호가 인가되면 셋(set)되어 상기 제2레귤레이터에 동작가능신호를 인가하는 래치단, 장치반전에 대한 제어를 수행함과 더불어 리모콘으로부터 전원 오프(OFF) 신호가 인가되면 상기 래치단을 리셋(reset) 시키고, 후술되어질 스위치 구동단에 소정의 스위칭 제어신호를 출력하는 제어수단, 및 상기 제어수단으로부터 출력된 소정의 스위칭 제어신호를 근거로 하여 상기 스위치를 온/오프 제어하는 스위치 구동수단을 포함하여 구성된 것을 특징으로 한다.When the television receiver is in the power off state, the television receiver is powered off by powering off all components except the components for starting the television receiver when a power on signal is applied from the remote control. The present invention relates to a power supply control apparatus for a television receiver capable of minimizing power consumption. The television receiver includes a first transformer for transforming power input from a power plug into a standby power supply, and a power input from a power plug. A second transformer for transforming and supplying the second transformer to the main power supply unit, switch means for switching the power applied from the power plug to the second transformer, and a series of devices for operating the television receiver based on the power supplied from the first transformer The first level to supply predetermined standby power to Based on the power supplied from the first transformer, the second regulator for supplying the operating power to the control means to be described later in accordance with the operation signal output from the latch stage to be described later, based on the power supplied from the first regulator When the power ON signal is applied from the remote controller, the latch stage is set to apply the operation enable signal to the second regulator, the control of the device reversal is performed, and the power OFF signal is applied from the remote controller. A control means for resetting the latch stage and outputting a predetermined switching control signal to a switch driving stage to be described later; and controlling the switch on / off based on a predetermined switching control signal output from the control means. Characterized in that configured to include a switch drive means.

Claims

1. A television receiver comprising: a first transformer for transforming power input from a power plug into a standby power supply unit; a second transformer for transforming power input from a power plug into a main power supply; and a second transformer from the power plug. Switch means for switching the power applied to the first regulator based on the power supplied from the first transformer, a first regulator for supplying a predetermined standby power to a series of devices for operating the television receiver, supplied from the first transformer A second regulator for supplying operation power to a control means to be described later according to an operation enable signal output from a latch stage to be described later based on the power, and a power-on signal from the remote controller based on the power supplied from the first regulator. When applied, it is set to move to the second regulator. A latch stage for applying an enable signal and the control of the entire apparatus, and when the power OFF signal is applied from the remote controller, resets the latch stage, and a predetermined switching control signal to a switch driving stage to be described later. And a switch driving means for controlling the switch on / off based on a predetermined switching control signal output from the control means.
