본 고안은 모니터나 텔레비젼에서 화상의 수평위치를 마음대로 조정할 수 있는 수평센터 조정회로에 관한 것으로, 특히 센터링볼륨저항에 전류가 적게 흐르게 하여 열이 별로 발생되지 않고, 화상의 수평위치를 쉽게 조정할 수 있게한 수평센터 조정회로에 관한 것이다.The present invention relates to a horizontal center adjustment circuit that can adjust the horizontal position of an image freely on a monitor or a television. In particular, a small current flows through the centering volume resistance so that heat is not generated and the horizontal position of the image can be easily adjusted. It relates to a horizontal center adjustment circuit.

종래의 수평센터 조정회로는 제1도에 도시한 바와 같이, 전원단자(B+)가 플라이백트랜스(FBT)의 일차권선을 통해 수평출력트랜지스터(Q1)의 콜렉터, 다이오드(D1) 및 콘덴서(C1)에 접속되고, 그 접속점은 수평편향요크(H-DY)와 병렬 접속된 선형코일(L1) 및 저항(R1)을 통해 센터링볼륨저항(VR1)이 가변탭에 접속되고, 이 센터링볼륨저항(VR1)의 양측단(a, b)은 다이오드(D2), (D3)를 각기 통해 콘덴서(C2)에 접속된 후 그 접속점이 쵸크코일(L2)을 통해 전원단자(B+)에 접속되어 구성된 것으로 상기에서 콘덴서(C1)는 공진용이고, 다이오드(D1)는 댐핑용이다.In the conventional horizontal center adjusting circuit, as shown in FIG. 1, the power supply terminal B + is connected to the collector of the horizontal output transistor Q 1 , the diode D 1 , and the primary winding of the flyback transformer FBT. The centering volume resistance VR 1 is connected to the variable tap through a linear coil L 1 and a resistor R 1 connected in parallel with the capacitor C 1 , the connection point of which is connected in parallel with the horizontal deflection yoke H-DY. Both ends (a, b) of the centering volume resistor (VR 1 ) are connected to the capacitor (C 2 ) via diodes (D 2 ) and (D 3 ), respectively, and their connection points are choke coils (L 2 ). and a power supply terminal (B +) is that the capacitor (C 1) in the constructed for connection to the resonator via a diode (D 1) is for damping.

이와 같이 구성된 종래회로의 동작과정을 설명하면 다음과 같다.Referring to the operation of the conventional circuit configured as described above are as follows.

전원단자(B+)에 전원이 인가된 상태에서 수평드라이브펄스단자(P)에 펄스신호가 출력되면 트랜지스터(Q1)가 온되므로 플라이백트랜스(FBT)의 일차권선 및 콘덴서(C1)에 의한 공진전류와, 다이오드(D1)에 의한 댐핑전류가 흐르게 되어 수평편향요크(H-DY)에 톱니파 신호가 인가되고 이 톱니파 신호는 선형코일(L1)을 통해 수평 선형이 보정된 후 센터링볼륨저항(VR1) 및 다이오드(D3)를 통해 콘덴서(C2)로 흐르게 되고, 한편 전원단자(B+)에 인가된 직류전압은 쵸크코일(L2) 및 다이오드(D2), 센터링볼륨저항(VR1)을 통해 수평편향요크(H-DY)에 인가되는데, 이때 수평편향요크(H-DY)에 흐르는 직류전류량에 따라 수평위치가 변화한다.When the pulse signal is output to the horizontal drive pulse terminal P while the power is applied to the power terminal B + , the transistor Q 1 is turned on, so that the primary winding and the capacitor C 1 of the flyback transformer FBT are turned on. The resonance current and the damping current caused by the diode D 1 flow to the horizontal deflection yoke H-DY, and the sawtooth signal is centered after the horizontal linearity is corrected through the linear coil L 1 . It flows to the capacitor C 2 through the volume resistor VR 1 and the diode D 3 , while the DC voltage applied to the power supply terminal B + is choke coil L 2 , diode D 2 , and centering. It is applied to the horizontal deflection yoke (H-DY) through the volume resistance (VR 1 ), at which time the horizontal position changes according to the amount of DC current flowing through the horizontal deflection yoke (H-DY).

즉, 센터링볼륨저항(VR1)의 가변탭이 그의 일측단자(a)에 위치하였을 경우에는 다이오드(D2) 및 그 센터링볼륨저항(VR1)을 통해 수평편향요크(H-DY)에 많은 직류전류가 흐르므로 화면의 수평위치가 우측으로 평행이동하고, 센터링볼륨저항(VR1)의 가변탭이 그의 타측단(b)에 위치하였을 경우에는 그 센터링볼륨저항(VR1)을 통해 수평편향요크(H-DY)에 흐르는 직류 전류량이 적게 되어 화면의 수평위치가 좌측으로 평행이동하게 된다. 그리고 쵸크코일(L2)은 수평편향요크(H-DY)의 인덕턴스 값을 변화시켜 센터링볼륨저항(VR1)의 중앙에서 화상의중앙이 일치하게 된다.That is, when the variable tap of the centering volume resistor VR 1 is located at one terminal (a) thereof, a large amount of horizontal deflection yoke H-DY is provided through the diode D 2 and the centering volume resistor VR 1 . DC current is made to flow, because the horizontal position of the screen, parallel shifts to the right, and if the variable tap of the centering volume resistance (VR 1) hayeoteul located at his other end (b), the horizontal through the centering volume resistance (VR 1) bias As the amount of DC current flowing through the yoke (H-DY) decreases, the horizontal position of the screen moves to the left. The choke coil L 2 changes the inductance value of the horizontal deflection yoke H-DY so that the center of the image coincides at the center of the centering volume resistance VR 1 .

그러나, 이러한 종래의 회로에 있어서는 수평편향요크(H-DY)에 흐르는 톱니파 신호의 전류를 센터링볼륨저항(VR1)만으로 조정하기 때문에 센터링볼륨저항(VR1)에 많은 전류가 흘러 열이 많이 발생되고, 이에 따라, 센터링볼륨저항(VR1)만으로 조정하기 때문에 센터링볼륨저항(VR1)에 많은 전류가 흘러 열이 많이 발생되고, 이에 따라, 센터링볼륨저항(VR1)은 용량이 커야 하고, 조정상의 한계가 발생되는 결점이 있었다.However, flowing a large current at the centering volume resistance (VR 1) generate a lot of heat to In the horizontal deflection yoke current of the sawtooth wave signal flowing in the (H-DY) in the conventional circuit because the adjustment of only the centering volume resistance (VR 1) As a result, since only a centering volume resistance VR 1 is adjusted, a lot of current flows through the centering volume resistance VR 1 to generate a lot of heat. Accordingly, the centering volume resistance VR 1 must have a large capacity. There was a flaw in the adjustment limitation.

본 고안은 이러한 점을 감안하여, 수평편향요크와 병렬로 센터링코일과 센터링볼륨저항을 병렬접속하여 센터링볼륨저항에 많은 전류가 흐르지 않게 함으로써 센터링볼륨저항에서 많은 열이 발생되지 않고, 그의 용량이 작으며,조정상의 한계가 없게 안출한 것으로, 이를 첨부된 고안의 도면에 의하여 상세히 설명하면 다음과 같다.In view of this, the present invention connects the centering coil and the centering volume resistor in parallel with the horizontal deflection yoke so that a large amount of current does not flow in the centering volume resistance, so that much heat is not generated in the centering volume resistance, and its capacity is small. And, there is no limit on the adjustment, which will be described in detail by the accompanying drawings of the invention as follows.

제2도는 본 고안의 수평센터 조정회로도로서 이에 도시한 바와 같이, 전원단자(B+)가 플라이백트랜스(FBT)의 일차권선을 통해 수평출력트랜지스터(Q1)의 콜렉터, 공진용콘덴서(C1) 및 댐핑용다이오드(D1)에 접속되고, 그 전원단자(B+)가 쵸크코일(L2)을 통해 콘덴서(C2)에 접속되어 그 접속점이 다이오드(D2)(D3)를 통해 센터링볼륨저항(VR1)의 양측단자(a), (b)에 접속된 수평센서 조정회로에 있어서, 상기 수평출력트랜지스터(Q1)의 콜렉터를 병렬접속된 저항(R1) 및 선형코일(L1)을 통한 후 수평편향요크(H-DY)를 통해서는 상기 콘덴서(C2)에 접속하고 저항(R3) 및 센터링코일(L3)을 통해서는 상기 센터링볼륨저항(VR1)의 가변탭에 접속하여 구성한 것으로, 도면의 설명중 미설명부호 P는 수평 드라이브 펄스단자이고, Vo는 플라이백트랜스(FBT)의 이차권선 전압 출력단자이다.2 is a horizontal center adjustment circuit diagram of the present invention, as shown in FIG. 2, the power supply terminal B + is the collector of the horizontal output transistor Q 1 and the resonant capacitor C through the primary winding of the flyback transformer FBT. 1 ) and the damping diode D 1 , the power supply terminal B + of which is connected to the capacitor C 2 through the choke coil L 2 , and its connection point being a diode D 2 (D 3 ). In the horizontal sensor adjusting circuit connected to both terminals (a) and (b) of the centering volume resistor (VR 1 ) through the resistor, the collector of the horizontal output transistor (Q 1 ) connected in parallel with the resistor (R 1 ) and linear After the coil (L 1 ) through the horizontal deflection yoke (H-DY) is connected to the capacitor (C 2 ) and through the resistor (R 3 ) and the centering coil (L 3 ) the centering volume resistance (VR 1) In this figure, reference numeral P denotes a horizontal drive pulse terminal, and Vo denotes a flyback transformer (FBT). Winding a voltage output terminal.

이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

전원단자(B+)에 전원이 인가된 상태에서 수평드라이브펄스단자(P)에 펄스신호가 출력되면(Q1)가 온되므로 상기와 동일하게 그의 콜렉터에 톱니파 신호가 출력되고, 이 톱니파 신호는 병렬접속된 저항(R1) 및 선형코일(L1)을 통하게 되고, 이 톱니파 신호의 전류는 수평편향요크(H-DY)를 통해 콘덴서(C2)로 흐르게 됨과 동시에 저항(R3) 및 센터링코일(L2), 센터링볼륨저항(VR1), 다이오드(D3)를 통해서도 콘덴서(C2)로 흐르게 된다.When a pulse signal is output (Q 1 ) to the horizontal drive pulse terminal P while the power is applied to the power supply terminal B + , the sawtooth signal is output to its collector as described above. Through the parallel connected resistor (R 1 ) and linear coil (L 1 ), the current of the sawtooth signal flows to the capacitor (C 2 ) through the horizontal deflection yoke (H-DY) and at the same time the resistor (R 3 ) and The condenser C 2 also flows through the centering coil L 2 , the centering volume resistance VR 1 , and the diode D 3 .

한편, 전원단자(B+)에 인가된 직류전류는 쵸크코일(L2) 및 다이오드(D2), 센터링볼륨저항(VR1), 센터링코일(L3), 저항(R3)을 통해 흐르게 된다.Meanwhile, the DC current applied to the power supply terminal B + flows through the choke coil L 2 and the diode D 2 , the centering volume resistor VR 1 , the centering coil L 3 , and the resistor R 3 . do.

여기서, 센터링코일(L3)에 흐르게 전류는 수평편향요크(H-DY)에 흐르는 전류에 비해 아주 작게 흐른다.Here, the current flowing in the centering coil (L 3 ) flows very small compared to the current flowing in the horizontal deflection yoke (H-DY).

그리고, 상기의 설명에서와 같이 센터링볼륨저항(VR1)이 가변탭이 그의 일측단(a)에 위치하게 되면 다이오드(D2)에는 많은 전류가 흐르게 되고, 다이오드(D3)에는 적은 전류가 흐르게 되어 화면의 수평위치는 우측으로 평행이동되고, 센터링볼륨저항(VR1)이 가변탭이 그의 타측단(b)에 위치 하게 되면 다이오드(D2)에는 적은 전류가 흐르게 되고, 다이오드(D3)에는 많은 전류가 흐르게 되어 화면의 수평위치는 좌측으로 평행이동된다.As described in the above description, when the centering volume resistor VR 1 is positioned at one side end a of the variable tap, a large current flows through the diode D 2 , and a small current flows through the diode D 3 . When the horizontal position of the screen is moved in parallel to the right side, when the centering volume resistance VR 1 is located at the other end b of the variable tap, a small current flows in the diode D 2 and the diode D 3. ) A lot of current flows and the horizontal position of the screen is moved to the left in parallel.

이상에서와 같이 본 고안은 수평편향요크에 센터링코일 및 센터링볼륨저항이 병렬 접속되어 전류의 흐름이 양분되므로 센터링코일과 센터링볼륨저항에 적은 전류가 흘러도 수평센터 조정이 가능하게 되고, 센터링코일의 인덕턴스 값을 변화시켜 센터링 가변범위를 임의로 변경시킬 수 있게 되며, 이에 따라, 센터링코일 및 센터링볼륨저항의 과열을 방지하고, 소요량의 센터링볼륨저항을 사용할 수 있는 이점이 있게 된다.As described above, since the centering coil and the centering volume resistance are connected in parallel to the horizontal deflection yoke, the flow of current is divided so that the centering coil and the centering volume resistance can be adjusted even if a small current flows, and the inductance of the centering coil is achieved. It is possible to change the centering variable range arbitrarily by changing the value, thereby preventing the overheating of the centering coil and the centering volume resistance, and having the advantage of using the required centering volume resistance.
