본 고안은 원격 조정회로에 보조 전원이 인가되면 계전기를 구동시켜 주 회로에 교류전원을 인가시키고, 주 회로에 교류 전원이 인가되면 원격 조정회로에 주전원을 인가시키는 원격 조정 방식의 텔레비젼 보조 전원회로에 관한 것으로, 특히 정전압 회로를 사용하여 원격조정 회로에 보조전원을 인가시키고, 주회로에 전원이 인가되면 원격 조정회로에 주 전원과 별도의 보조전원을 인가시키며, 정진압 회로는 차단시키도록한 텔레비젼 보조전원 회로에 관한 것이다.The present invention is applied to a TV auxiliary power supply circuit of a remote control method that drives the relay when the auxiliary power is applied to the remote control circuit to apply AC power to the main circuit, and when the AC power is applied to the main circuit, to supply the main power to the remote control circuit. In particular, the auxiliary voltage is applied to the remote control circuit using a constant voltage circuit, and when power is applied to the main circuit, an auxiliary power source separate from the main power is applied to the remote control circuit, and the constant voltage suppressor circuit is cut off.

However, this is because the induction phenomenon is generated using the transformer (T), not only the TV screen is not clean, but also can not be composed of an integrated circuit, such as bulky, expensive production costs, there were various defects.

본 고안은 상기의 점을 감안하여, 정전압 회로(5)를 사용하여 원격 조정회로(2)에 보조전원(B1)을 인가하고, 계진기(RL1)가 구성되어 주 회로(4)에 교류전원(AC)이 인가되면 정전압 회로(5)를 차단시키며, 원격조정회로(2)에는 주 전원(B2)과 별도의 보조전원(B1)이 인가되도록 안출한 것으로, 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.In view of the above, the present invention applies the auxiliary power supply B 1 to the remote control circuit 2 by using the constant voltage circuit 5, and the reciprocating device RL 1 is configured to provide alternating current to the main circuit 4. When the power source AC is applied, the constant voltage circuit 5 is cut off, and the remote control circuit 2 is designed to be supplied with a main power source B 2 and a separate auxiliary power source B 1 , according to the accompanying drawings. Referring to the configuration and effect of the present invention in detail as follows.

제2도와 제3도에 도시된 바와같이, 원격조정회로(2)에 보조전원(B1)이 인가되면, 저항(R1),(R2) 및 트랜지스터(TR1)로 구성된 계전기 구동회로(3)에 전원(B2)이 인가되어 계전기(RL1)가 구동되고, 계전기(RL1)가 구동되어 주 회로(4)에 교류전원(AC)이 인가되면 원격 조정회로(2)에 주 전원(B3)이 인가되는 보조 전원 회로에 있어서, 교류전원 (AC)에 접속된 전원스위치(SW1)를 다이오드(D1)를 통해 저항(R3),(R4)과 콘덴서(C1)에 각각 접속하여, 저항(R3),(R4)을 트랜지스터(TR2)의 콜렉터와 베이스에 각각 접속하며, 트랜지스터(TR2)의 에미터는 베이스와 에미터에 정전압 다이오드(D2)와 다이오드 (D3)가 각각 접속된, 트랜지스터(TR3)의 콜랙터에 접속하여 정전압회로(5)를 구성하고, 다이오드(D3)의 출력축은 2차 정전압회로(6)를 통하여 원격 조정회로(2)의 집적회로(IC1)에 접속하는 한편, 즉 회로(4)의 전원(B4)출력 단자는 저항 (R5)를 통해, 콜렉터가 정전압회로(5)의 트랜지스터(TR2)의 베이스에 접속된 트랜지스터(TR4)의 베이스에 접속하여 제어회로(7)를 구성하며, 주 회로(4)의 전원(B3) 출력 단자는 원격 조정회로(2)와, 다이오드(D4)를 통해 상기 정전압회로(6)의 입력측에 접속하며, 또한 원격조정회로(2)의 전원단자(B5)에 접속하여 구성한 것으로, 상기에서 계전기 스위치 (SW2)는 계전기(RL1)에 연동되어 개폐되는 스위치이고, 계전기 개폐용 스위치(SW3)는 단락되면 계전기 구동회로(3)에 전원(B2)이 인가되는 스위치이며, 미설명부호 D5는 다이오드, C2는 콘덴서, R6,R7은 저항이다.As shown in FIG. 2 and FIG. 3, when the auxiliary power source B 1 is applied to the remote control circuit 2, a relay driving circuit composed of resistors R 1 , R 2 , and transistors TR 1 . When power supply B 2 is applied to (3) and relay RL 1 is driven and relay RL 1 is driven and AC power is applied to main circuit 4, remote control circuit 2 is applied. In the auxiliary power circuit to which the main power source B 3 is applied, the power switch SW 1 connected to the AC power source AC is connected to the resistors R 3 and R 4 and the capacitor ( C ) through the diode D 1 . respectively connected to C 1), the resistance (R 3), (R 4 ) a transistor (TR 2) in and respectively connected to the collector and the base, the transistor (TR 2) the emitter voltage on the emitter base and the emitter diode (D a 2 ) and the diode D 3 are connected to the collector of the transistor TR 3 connected to each other to form a constant voltage circuit 5, and the output shaft of the diode D 3 is connected to the secondary constant voltage circuit 6. Remote control circuit (2 Is connected to the integrated circuit IC 1 , that is, the power supply B 4 output terminal of the circuit 4 is connected via a resistor R 5 so that the collector is the base of the transistor TR 2 of the constant voltage circuit 5. Connected to the base of the transistor TR 4 connected to form a control circuit 7, and the power supply B 3 output terminal of the main circuit 4 connects the remote control circuit 2 and the diode D 4 . It is connected to the input side of the constant voltage circuit 6 and connected to the power supply terminal (B 5 ) of the remote control circuit (2), wherein the relay switch (SW 2 ) is linked to the relay (RL 1 ) The switch for opening and closing the switch SW 3 is a switch to which the power supply B 2 is applied to the relay driving circuit 3 when the short circuit is closed, the reference numeral D 5 is a diode, C 2 is a capacitor, R 6 , R 7 is a resistance.

이와같이 구성된 본 고안에 있어서 스위치가 (SW1)가 단락되어 교류전원(AC)이 인가되면 다이오드(D1)와 콘덴서(C1)로 정류되어 트랜지스터(TR2)의 콜렉리에 인가되고 트랜지스터(TR2)(TR3)의 베이스에는 정전압 다이오드(D2)에 의해 정전압이 인가되므로 트랜지스터(TR2)(TR3)가 온되며, 이에 따라 정전압 회로(5)의 출력측에는 정전압이 출력되고, 이 정전압은 정전압회로(6)를 통하여 원격 조정회로(2)의 집적회로(IC1)에 인가되며, 또한 계전기(RL1)를 통해 계전기 구동회로(3)의 트랜지스터(TR1)콜렉터에 인가된다.In the present invention configured as described above, when the switch (SW 1 ) is short-circuited and the AC power source (AC) is applied, the switch is rectified by the diode (D 1 ) and the capacitor (C 1 ) and applied to the collector of the transistor (TR 2 ) and the transistor (TR). 2 ) Since the constant voltage is applied by the constant voltage diode D 2 to the base of the TR 3 , the transistors TR 2 and TR 3 are turned on. Accordingly, the constant voltage is output to the output side of the constant voltage circuit 5. The constant voltage is applied to the integrated circuit IC 1 of the remote control circuit 2 via the constant voltage circuit 6 and to the transistor TR 1 collector of the relay drive circuit 3 via the relay RL 1 . .

이때 스위치(SW3)를 단락하면 원격 조정회로(2)의 집적회로(IC1)에서 전원(B2)이 출력되어 계전기 구동회로(3)의 트랜지스터(TR1)베이스에 인가되므로 트랜지스터(TR1)가 온되고, 이에 따라 계전기(RL1)가 구동되어 계전기 스위치(SW2)가 단락되므로 주 회로(4)에는 교류전원(AC)이 인가되어 주 회로(4)가 동작된다. 따라서 주 회로(4)에서 전원(B3)(B4)이 출력되어 전원(B4)은 제어회로(7)의 트랜지스터(TR4)베이스에 인가되므로 트랜지스터(TR4)가 온되어 그의 클렉이 진위가 떨어지게되고, 이에따라 트랜지스터(TR2)(TR3)가 오프되어 정전압 회로(5)가 차단된다. 그러나 전원(B3)은 다이오드(D4)와 정전압 회로(6)를 통해 원격 조정회로(2)의 보조전원(B1)으로 인가되므로 상기에서와 같이 계전기(RL1)는 계속 구동하게 되어, 주 회로(4)에는 교류전원(AC)이 계속 공급된다. 따라서 주 회로(4)에서 출력된 전원(B3)이 주 전원단자(P5)에 계속 인가되므로 원격 조정회로(2)는 동작 상태로 된다.At this time, when the switch SW 3 is shorted, the power supply B 2 is output from the integrated circuit IC 1 of the remote control circuit 2 and applied to the transistor TR 1 base of the relay driving circuit 3. 1 ) is turned on, and thus relay RL 1 is driven to short-circuit relay switch SW 2 , so AC power is applied to main circuit 4 to operate main circuit 4. Therefore, the power supply B 3 (B 4 ) is output from the main circuit 4 and the power supply B 4 is applied to the base of the transistor TR 4 of the control circuit 7, so that the transistor TR 4 is turned on and its clock is selected. This authenticity is lowered, and accordingly, the transistor TR 2 (TR 3 ) is turned off to cut off the constant voltage circuit 5. However, since the power supply B 3 is applied to the auxiliary power supply B 1 of the remote control circuit 2 through the diode D 4 and the constant voltage circuit 6, the relay RL 1 continues to operate as described above. The main circuit 4 is continuously supplied with the AC power source AC. Therefore, since the power supply B 3 output from the main circuit 4 is continuously applied to the main power supply terminal P 5 , the remote control circuit 2 is in an operating state.

이상에서와 같이 본 고안은 별도의 트랜스(T)를 사용하지 않고 보조전원(B1)을 원격조정회로(2)에 인가시키므로서 유도현상이 발생되지 않아 깨끗한 화면을 시청할 수 있고, 집적회로로 구성하여 제품의 생산 원가를 절감할 수 있으며, 최근의 텔레비젼의 일반적인 추세인 자동 진압 조정 회로를 적용할 경우에는 복잡한 정전압 전원 장치를 없앤 수 있는 등 여러가지 장점이 있다.As described above, the present invention does not induce a phenomenon by applying an auxiliary power source B 1 to the remote control circuit 2 without using a separate transformer T, so that a clean screen can be viewed and an integrated circuit It is possible to reduce the production cost of the product, and when applying the automatic suppression control circuit which is a general trend of the recent TV, there are various advantages such as eliminating complicated constant voltage power supply.
