미설명부호 4는 보조보빈을 나타낸다.Reference numeral 4 denotes an auxiliary bobbin.
제1도는 본 고안의 회로도를 나타낸 것으로, 전원스위칭부(1)와 주전원부(2)에 있는 트랜지스터(Q1),(Q2)의 각 베이스에는 수평구동 트랜스포머가 연결되어서 수평동기신호가 입력되고, 직류공급단(DC)에는 입력전원이 다이오드를 통해 정류되는 정류회로가 연결되며, 고압전원부(3)에서는 주전원부(2)의 1차권선(N2)으로 부터 고전압이 유기되어서 애노드(AN)를 통해 브라운관으로 공급된다.1 is a circuit diagram of the present invention, a horizontal drive transformer is connected to each base of the transistors Q1 and Q2 in the power supply switching unit 1 and the main power supply unit 2, and a horizontal synchronous signal is input thereto. A rectifier circuit in which input power is rectified through a diode is connected to the DC supply terminal (DC). In the high voltage power supply unit (3), a high voltage is induced from the primary winding (N2) of the main power supply unit (2) so that the anode (AN) is connected. Through the CRT.
따라서 입력단의 전원회로에서는 파워트랜스를 거치지 않고 다이오드로 구성된 정류회로에서 정류되는 직류전압이 플라이백 트랜스포머(FBT)의 전원스위칭부(1)에 있는 보조권선(N1)의 직류공급단(DC)으로 공급되도록 하면, 수평구동트랜스포머로 부터 수평등기신호를 받아서 온-오프되는 트랜지스터(Q1)에 의하여 보조권선(N1)에 공급된 전압에 따라 주전원부(2)에 있는 1차권선(N2)으로 전압이 유기된다. 이때 유기되는 전압은 보조권선(N1)과 1차권선(N2)의 권선비에 따라 조정되는 데 댐퍼다이오드(D1)와 콘덴서(C1)에 의해 정류되어서 플라이백 트랜스포머(FBT) 자체의 동작전압(B+전압)으로 이용된다.Therefore, in the power circuit of the input terminal, the DC voltage rectified in the rectifier circuit composed of diodes does not go through the power transformer to the DC supply terminal (DC) of the auxiliary winding N1 in the power switching unit 1 of the flyback transformer (FBT). When supplied, the voltage is supplied to the primary winding N2 in the main power supply unit 2 in accordance with the voltage supplied to the auxiliary winding N1 by the transistor Q1 that receives the horizontal registration signal from the horizontal driving transformer and is turned on and off. This is organic. At this time, the induced voltage is adjusted according to the turns ratio of the auxiliary winding N1 and the primary winding N2, and is rectified by the damper diode D1 and the condenser C1, thereby operating the voltage B of the flyback transformer FBT itself. + Voltage).
이와같이 전압이 공급되어서 주전원부(2)에서는 편향에 필요한 트랜지스터(Q2)의 컬렉터전압을 얻을 수 있는 한편, 주전원주(2)의 1차권선(N2)과 고압전원부(3)의 2차권선(N3)의 권선비에 따라 2차권선(N3)에 고압이 유기되도록 하여 다이오드(D2)를 통해 브라운관용 애노드(AN)로 고압이 동급될 수 있는 것이다.In this way, the voltage is supplied so that the collector voltage of the transistor Q2 necessary for deflection can be obtained from the main power supply unit 2, while the primary winding N2 of the main power supply main unit 2 and the secondary winding of the high voltage power supply unit 3 ( The high pressure is induced in the secondary winding N3 according to the turns ratio of N3) so that the high pressure can be equalized to the cathode for the tube CAN through the diode D2.

제2도는 본 고안의 실시예를 나타낸 것으로서, 입력전원으로 부터 정류된 전압을 주전원부(2)의 1차코일(N2)로 유기시키는 보조권선(N1)이 주전원부(2)의 1차권선(N2) 및 고압전원부(3)의 2차권선(N3) 그리고 저압유기용의 3차권선(N4)과는 별도로 설치된 보조보빈(4)에 권취됨을 나타낸다.2 shows an embodiment of the present invention, in which the auxiliary winding N1 for inducing the voltage rectified from the input power supply to the primary coil N2 of the main power supply unit 2 is the primary winding of the main power supply unit 2. (2) and the secondary winding (N3) of the high-voltage power supply section (3) and the secondary bobbin (4) provided separately from the tertiary winding (N4) for low pressure organic.
이와같이 보조권선(N1)이 1차권선(N2) 및 2차권선(N3), 3차권선(N4)과는 별도로 설치된 보조보빈(4)에 권취되도록 하므로써 1차권선(N2)과의 결합력이 증가되어 효율이 증가된다.As such, the auxiliary winding (N1) is wound on the auxiliary bobbin (4) installed separately from the primary winding (N2), the secondary winding (N3), and the tertiary winding (N4), so that the coupling force with the primary winding (N2) is reduced. Increase the efficiency.
제3도는 본 고안의 종단면도를 나타낸 것으로서, 보조보빈(4)에 권취되어 있는 보조권선(N1)은 다수개의 블럭으로 분리 권취시키므로써 전기적 절연이 높아지게 된다.3 is a longitudinal sectional view of the present invention, the auxiliary winding (N1) wound on the auxiliary bobbin (4) is separated by winding a plurality of blocks, the electrical insulation is increased.
상기한 바와 같이 본 고안은 텔레비젼이나 모니터 등의 전원회로에 설치된 파워트랜스를 삭제하고, 다이오드로 구성된 정류회로로 부터 출력되는 정류전압을 전원스위칭부(1)에 있가하여, 이로부터 1차권선(N1)에 유기된 전압이 편향에 필요한 트랜지스터(Q2)의 컬램터 전압으로 이용되는 한편 2차권선(N3)에 유기된 전압이 브라운관용 애노드(AN)로 공급되고, 3차권선(N3)에서 유기된 저전압이 셋트상의 각 필요한 회로부로 공급되도록 하므로써 원가절감 및 기기의 소형화를 성취할 수 있고 제품생산성을 향상시킬 수 있는 효과가 있다.As described above, the present invention eliminates the power transformer installed in a power supply circuit such as a television or a monitor, and transfers the rectified voltage output from the rectifier circuit composed of diodes to the power supply switching unit 1, whereby the primary winding ( The voltage induced in N1) is used as the collector voltage of transistor Q2 necessary for deflection, while the voltage induced in secondary winding N3 is supplied to the cathode tube AN, and in the tertiary winding N3. Since the induced low voltage is supplied to each necessary circuit part on the set, cost reduction and device miniaturization can be achieved and product productivity can be improved.
