The output of the lead-out unit 10 is connected to the bias resistor R 1 , the zener diode ZD 1 for constant voltage, and the constant voltage transistor Q 1 connected to the noise removing capacitor C 3 (C 4 ). 30) to drive.

그리고 제어부(40)는 마이콤(30)의 출력(P2)이 정전압부(20)의 출력과 함께 바이어스 저항(R2)(R3)과 접속된 트랜지스터(Q2)(Q3)를 구동하게 구성한 후 스탠바이 전원 인출부(10)의 출력과 함께 코일(L1)과 릴레이 스위치(RY1)로 구성된 릴레이(RY1)를 구동시켜 저항(R4)(R5) 및 잡음제거용 콘덴서(C5)를 통하여 수평 발진소자(IC1)에 인가되는 메인전원을 제어하게 구성한 것이다.In addition, the controller 40 drives the transistor Q 2 (Q 3 ), in which the output P 2 of the microcomputer 30 is connected to the bias resistor R 2 (R 3 ) together with the output of the constant voltage unit 20. After the configuration, the resistor (R 4 ) (R 5 ) and the noise canceling capacitor are driven by driving the relay (RY 1 ) consisting of the coil (L 1 ) and the relay switch (RY 1 ) together with the output of the standby power supply unit 10. It is configured to control the main power applied to the horizontal oscillation element (IC 1 ) through (C 5 ).

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

본 고안의 회로도에서 플러그(P1)에 인가된 교류전원(AC)이 정류용 브리지다이오드(BD1)와 평활용콘덴서(C1)를 통하여 직류로 변환되어 스위칭 모우드 파우어 서플라이(SMPS)의 쵸퍼트랜스(T2)에 인가된 후 레귤레이터(1)를 통하여 출력단자(O1)후단에 메인전원을 인가하며 이때 쵸퍼트랜스(T1)의 2차측으로부터 유기된 전원이 정류용 다이오드(D1)와 평활용 콘덴서(C2)를 통하여 직류로 변환된 후 바이어스 저항(R1)과 잡음제거용 콘덴서(C3) 및 정전압용 제너다이오드(ZD1)를 통하여 트랜지스터(Q1)를 "턴온" 시킴에 따라 마이콤(3)의 단자(P1)에 일정전원이 인가되어 마이콤(30)을 구동시키는 것이다.In the circuit diagram of the present invention, the AC power source AC applied to the plug P 1 is converted into direct current through the rectifying bridge diode BD 1 and the smoothing capacitor C 1 , and the chopper of the switching mode power supply (SMPS) is applied. After being applied to the transformer T 2 , the main power is applied to the rear end of the output terminal O 1 through the regulator 1, and at this time, the power induced from the secondary side of the chopper transformer T 1 is rectified diode D 1 . and a smoothing capacitor bias resistor capacitor (R 1) and the noise and removed via a (C 2) converted into a direct current (C 3) and the constant-voltage zener diode transistor (Q 1) through (ZD 1) for a "turn-on" As a result, a constant power is applied to the terminal P 1 of the microcomputer 3 to drive the microcomputer 30.

여기서 초기 전원 인가시에는 마이콤(30)의 출력(P2)이 「L레벨」이 인가되어 트랜지스터(Q2)를 "턴오프"시키고 정전압용 트랜지스터(Q1)로부터 인가되는 정전압이 바이어스저항(R2)(R3)을 통하여 PNP형 트랜지스터(Q3)의 베이스측에 「H레벨」을 인가시켜 트랜지스터(Q3)를 "턴오프"시킴에 따라 코일(L1)의 여자 상태가 해제되어 릴레이 스위치(RS1)를 "오프"시키기 때문에 수평 발진소자(IC1)를 구동시키는 출력단자(O1)의 메인전원 공급이 차단됨으로서 TV가 구동되지 않게 되는 것이다.Here, when the initial power is applied, the output P 2 of the microcomputer 30 is applied with the "L level" to turn off the transistor Q 2 , and the constant voltage applied from the constant voltage transistor Q 1 is applied to the bias resistor ( R 2) (R 3) excited state releases the PNP-type transistor (coil (L 1) in accordance with Q 3) to "H level" on the base side is applied to the transistor (Q 3) of Sikkim "turned off" by the Since the relay switch RS 1 is "off", the main power supply of the output terminal O 1 for driving the horizontal oscillation element IC 1 is cut off so that the TV is not driven.

여기서 파우어가 "온"되면 마이콤(30)의 출력(P2)측으로부터 「H레벨」이 인가되어 트랜지스터(Q2)를 "턴온"시키고 정전압용 트랜지스터(Q1)로부터 인가되는 전원이 저항(R2)과 트랜지스터(Q2)를 통하여 접지로 흐름에 따라 트랜지스터(Q3)의 베이스측에 「L레벨」이 인가되어 트랜지스터(Q3)를 "턴온"시킨후 정류용 다이오드(D1)와 평활용 콘덴서(C2)를 통하여 인출된 스탠바이 전원이 코일(L1)을 여자시켜 릴레이 스위치(RS1)를 "온"시킴에 따라 출력단자(O1)의 메인전원이 릴레이 스위치(RS1)와 저항(R4)(R5) 및 잡음제거용 콘덴서(C5)를 통하여 수평 발진소자(IC1)를 구동시킴으로서 TV가 구동될 수 있는 것이다.Here, when the power is "on", the "H level" is applied from the output P 2 side of the microcomputer 30 to "turn on" the transistor Q 2 and the power applied from the constant voltage transistor Q 1 is a resistor ( R 2) and transistor (diode then Q 2) is the "L level" to the base side of the transistor (Q 3) with the passage in the ground is applied through the "turn on" the transistor (Q 3) rectifier (D 1) And the standby power source drawn out through the smoothing capacitor (C 2 ) excites the coil (L 1 ) to turn on the relay switch (RS 1 ), so that the main power source of the output terminal (O 1 ) is the relay switch (RS). 1 ), the TV can be driven by driving the horizontal oscillation element (IC 1 ) through the resistor (R 4 ) (R 5 ) and the noise canceling capacitor (C 5 ).

이상에서와 같이 본 고안은 메인전원을 유기시키는 스위칭 모우드 파우어 서플라이를 통하여 스탠바이 전원을 인가하게 한후 마이콤을 구동시켜 TV의 구동을 제어하게 구성한 것으로 회로구성이 간단하게 될 수 있으며 제품의 부피가 적어지게 될 수 있는 효과가 있는 것이다.As described above, the present invention is configured to control the driving of the TV by driving the microcomputer after the standby power is applied through the switching mode power supply which induces the main power. There is an effect that can be.
