Description
본 고안은 전자기기의 직류전압 강하 회로에 관한 것으로, 더욱 상세하게는 반도체 등과 같은 직접회로의 구동을 위한 저전압공급회로를 구성함에 있어서 그 구성을 단순화하고 발열을 최소화하여 직접도를 높임과 더불어 생산원가를 절감할 수 있도록 함을 목적으로 한 것이다.The present invention relates to a DC voltage drop circuit of an electronic device, and more particularly, in the construction of a low voltage supply circuit for driving an integrated circuit such as a semiconductor, the configuration is simplified and the heat generation is minimized to increase the directivity and produce the same. The aim is to reduce costs.
일반적으로, 전자기기에는 각 회로의 구동을 위하여 전원을 공급하는 전원부가 구비되어 있으며, 상기 전원부는 각 회로의 특성에 따라 알맞은 전압의 전원을 공급할 수 있게 구성되어 있다.In general, an electronic device includes a power supply unit for supplying power for driving each circuit, and the power supply unit is configured to supply power of a suitable voltage according to the characteristics of each circuit.
한편, 상기한 바와 같이 전원부를 통하여 전원을 공급받아 구동되는 회로를 구성함에 있어서 특정소자가 다른 소자의 구동전압과 상이한 전압으로 구동되는 경우 통상적으로는 전원부로부터 전원을 인가하여 회로를 구성하지만 회로의 직접도를 높이기 위하여 회로로 입력된 전압을 조정하는 전압조정부를 구비하여 특정소자에 알맞은 구동전압의 전원을 공급할 수 있게 구성하고 있으며, 이상과 같이 회로내에 전압조정부를 구비하는 전자기기의 일 예로는 CCTV등의 회로에 있어서 촬상부의 발진소자나, 영상처리부의 마이컴등이 회로의 다른 소자보다 낮은 전압으로 구동되게 구성되어 있는 것이다.On the other hand, in the configuration of a circuit driven by receiving power through the power supply unit as described above, when a specific device is driven at a voltage different from the driving voltage of another device, the circuit is generally configured by applying power from the power supply unit. In order to increase the direct degree, a voltage adjusting unit for adjusting a voltage input to a circuit is provided to supply power of a driving voltage suitable for a specific device. As an example of an electronic device including a voltage adjusting unit in a circuit as described above, In circuits such as CCTV, the oscillation element of the imaging unit, the microcomputer, etc. of the image processing unit are configured to be driven at a lower voltage than other elements of the circuit.
그러나, 상기한 바와 같이 회로에 있어서 다른 소자의 구동전압보다 낮은 전압으로 구동되는 특정소자에 전원을 조정하여 공급하는 전압조정부가 고직접화된 IC로 이루어져 있어 생산원가가 고가이며, 열이 발생하여 방열을 위한 일정 공간을 확보하여야 하므로 회로의 직접도가 저하되는 등의 문제점이 있었다.However, in the circuit as described above, since the voltage adjusting part for supplying power to a specific device driven by a voltage lower than the driving voltage of other devices is made of a highly integrated IC, the production cost is expensive and heat is generated. Since a certain space must be secured for heat dissipation, there is a problem such as a decrease in the directivity of the circuit.
이에, 본 고안은 상술한 문제점을 해결하기 위하여 안출한 것으로, 회로를 구성하는 소자중 다른 소자의 구동전압보다 낮은 전압으로 구동되는 반도체와 마이컴등과 같은 고직접회로로 이루어진 특정소자에 전압을 조정하여 공급하는 전압조정부를 다이오드로 구성한 것이다.Accordingly, the present invention has been made to solve the above-described problems, and adjusts the voltage to a specific device composed of a high direct circuit such as a semiconductor, a microcomputer, etc., which is driven at a voltage lower than the driving voltage of another device among the devices constituting the circuit. The voltage adjusting part to be supplied is composed of a diode.

이하, 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
본 고안은 회로의 구성을 단순화하여 생산원가를 절감하며 전자기기를 소형화할 수 있도록 한 것으로, 전자기기 회로를 구성하는 소자중 다른 소자의 구동전압보다 낮은 전압으로 구동되는 반도체와 마이컴등과 같이 고직접화된 특정소자에 전원 공급을 위한 전압조정부를 구성함에 있어서, 상기 전압조정부는 하나 이상의 다이오드(11)를 직렬로 연결하여 구성한 것이다.The present invention simplifies the circuit configuration to reduce the production cost and miniaturize the electronic device, such as semiconductors and microcomputers that are driven at a voltage lower than the driving voltage of other devices among the components of the electronic circuit. In configuring a voltage regulator for supplying power to a specific device, the voltage regulator is configured by connecting one or more diodes 11 in series.
여기서, 다이오드(11)와 출력단 사이에는 필터링코일(12)을 구비하고, 하나 이상으로 구성되는 다이오드(11)의 출력측에는 접지되는 필터링콘덴서(13)를 구비한 것이다.Here, the filtering coil 12 is provided between the diode 11 and the output terminal, and the filtering capacitor 13 is grounded on the output side of the diode 11 composed of one or more.
한편, 상기한 바와 같은 본 고안의 일 실시예로는 그 크기가 급속도로 소형화되고 있는 CCTV의 회로에 있어서, 촬상부의 발진소자에 전원을 공급하는 전압조정부를 하나 이상의 다이오드(11)로 구성하고, 영상처리부의 마이컴등에 전원을 공급하는 전압조정부 또한 하나 이상의 다이오드(11)로 구성하므로서 촬상부와 영상처리부를 소형화시켜 CCTV를 소형화할 수 있는 것이다.On the other hand, in one embodiment of the present invention as described above, in the CCTV circuit of which size is rapidly miniaturized, the voltage adjusting unit for supplying power to the oscillation element of the imaging unit is composed of one or more diodes 11, Since the voltage adjusting unit for supplying power to the microcomputer and the like of the image processing unit also includes one or more diodes 11, it is possible to miniaturize the CCTV by miniaturizing the imaging unit and the image processing unit.
이하, 본 고안의 작용에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.
상기한 바와 같이 전압조정부를 다이오드(11)로 구성한 본 고안은 전원부에서 인가된 전원이 다이오드(11)를 통과하면서 전압강하가 발생하게되는데, 상기 다이오드(11)에 의한 전압강하는 일반적으로 약 0.7V의 전압강하가 이루어지는 것이다.As described above, the present invention in which the voltage adjusting unit is constituted by the diode 11 generates a voltage drop while the power applied from the power supply unit passes through the diode 11, and the voltage drop by the diode 11 is generally about 0.7. The voltage drop of V is made.
이때, 상기 다이오드(11)는 순방향흐름에 의하여 전류를 통과시키면서 전압을 강하시키는 것으로 부하가 걸리지 않아 발열등의 현상이 발생하지 않는 것이다.At this time, the diode 11 is a voltage drop while passing the current by the forward flow does not take the load does not occur phenomenon such as heat.
따라서, 본 고안은 다이오드에 순방향으로 전원이 흐르게 하여 전압을 강하시켜 저전압에 의하여 구동되는 특정소자에 전원을 공급하므로서 발열이 생기지 않아 회로를 더욱 소형으로 구성할 수 있는 것이다.Therefore, the present invention allows the power to flow in the forward direction to the diode to drop the voltage to supply power to a specific device driven by a low voltage does not generate heat, so that the circuit can be made more compact.
또한, 고가의 IC를 사용하지 않으므로 생산원가를 절감할 수 있는 매우 유용한 것이다.In addition, since it does not use expensive IC, it is very useful to reduce the production cost.
