본 발명은 전원공급기에 관한 것으로, 특히 써지차단기능을 구비한 전원공급기에 관한 것이다.The present invention relates to a power supply, and more particularly, to a power supply having a surge blocking function.

전기를 사용하여 동작하는 전기기기나 산업용 기계는 인가되는 전압을 서서히 높여 갈 때, 그 기기나 기계 또는 부품이 인가된 전압을 견딜 수 있는 한계전압인 내전압(耐電壓)이 있어서, 이를 초과하는 과전압이 기기로 유입되면, 그 기기에 연결되어 있는 장치, 부품 등이 파손되거나 그 기기의 동작을 방해하게 된다. 이렇게 전기기기나 산업용 기계에 인가되는 전압에 유입되어 장치, 부품 등을 파손시키거나 그 기기의 동작을 방해하는 이상전압(異常電壓)을 써지(surge)라 한다.Electrical equipment or industrial machines operating using electricity have a withstand voltage, a limiting voltage that can withstand the applied voltage when the applied voltage is gradually increased. If it enters the device, the devices, parts, etc. connected to the device are damaged or interfere with the operation of the device. Surge is an abnormal voltage that flows into a voltage applied to an electric device or an industrial machine and damages a device, a part, or the like, or hinders the operation of the device.

이러한 써지는 자연적인 낙뢰현상이나, 전력계통 또는 대형 산업설비들에서 전압불균형 등의 원인으로 발생되어 배전 전원선, 데이타 통신회선 및 접지를 통하여 기기로 유입되어 문제를 일으키게 된다. 한편, 낙뢰와 같은 써지는 진폭이 매우 높고, 상승시간이 무척 빠르며, 지속시간(Duration time)이 짧은 주기(

Figure 112005033186707-PAT00001
)를 가진 임펄스(Impulse)형태 또는 진동(Oscillatory)형태의 파형이 0.5 Hz 안에서 정현파 전원 및 신호에 중첩되어 아주 빠르게 유입되는 전기적인 파형이다.These surges can be caused by natural lightning strikes or voltage imbalances in power systems or large industrial installations, causing them to enter the equipment through distribution power lines, data communication lines and ground. On the other hand, there are very high amplitudes such as lightning strikes, very fast rise times, and short duration times (
Figure 112005033186707-PAT00001
The impulse or oscillatory waveform with) is an electrical waveform that flows very quickly, overlapping a sinusoidal power source and signal within 0.5 Hz.

이러한 낙뢰와 같은 써지를 차단하기 위한 방법은 이미 공지된 바 있어서, 일반적으로 전원단자로부터 유입된 써지를 차단하기 위해 전원단자에 써지차단회로를 부가한다. 이러한 써지차단회로는 유도성 소자인 코일과 용량성 소자인 콘덴서로 구성되거나 또는 퓨즈와 저항값이 변화되는 가변저항기인 바리스터를 이용하여 구성하는 등 간단한 구성으로도 써지를 차단할 수 있다.Since a method for blocking a surge such as a lightning strike is already known, a surge blocking circuit is generally added to a power supply terminal to block a surge flowing from a power supply terminal. Such a surge interruption circuit may be constituted by a coil, which is an inductive element, and a capacitor, which is a capacitive element, or may be blocked by a simple configuration such as by using a fuse and a varistor, which is a variable resistor whose resistance value is changed.

도 1은 종래의 써지를 차단하기 위한 회로도를 도시한 것으로서, 퓨즈와 바리스터를 이용한 것을 나타낸 것이다.Figure 1 shows a circuit diagram for breaking a conventional surge, showing that using a fuse and a varistor.

도 1을 참조하면, 도시된 바와 같이 써지차단회로(10)는 전원단자로부터 유입된 전압의 써지를 차단하기 위해 전원단자의 입력부분에 퓨즈(10a)와 바리스터(10b)를 연결하여 일정기준 이상의 과전압이 유입되면, 발열에 의해 상기 퓨즈(10a)가 단락됨으로서 전기기기(20)로 써지가 유입되는 것을 차단한다. 그리고 상기 바리스터(10b)에서는 써지가 유입되면 저항값을 감소하여 전류를 증가시켜 접지되게 함으로서 써지가 전기기기(20)로 유입되는 것을 차단하게 된다.Referring to FIG. 1, the surge blocking circuit 10 connects a fuse 10a and a varistor 10b to an input portion of a power terminal to block a surge of voltage introduced from a power terminal. When the overvoltage flows in, the fuse 10a is short-circuited due to heat generation, thereby preventing surge from flowing into the electric device 20. In the varistor 10b, when the surge flows in, the resistance is decreased to increase the current to ground the surge so that the surge flows into the electric device 20.

한편, 이러한 써지차단회로는 여러 곳에 응용될 수가 있는데, 안테나와 연결된 케이블과 접속되는 전기기기에서 안테나로 유입된 써지를 차단하거나, 디지털카메라, 휴대용컴퓨터 등의 휴대용장치에 전원을 공급하기 위한 충전기에 유입된 써지를 차단하기 위해 이용될 수도 있으며, 또한 전원을 공급하는 전원공급기에서도 이용될 수도 있다.On the other hand, the surge blocking circuit can be applied to a number of places, such as to block the surge flowing into the antenna from the electrical equipment connected to the cable connected to the antenna, or to the charger for supplying power to portable devices such as digital cameras, portable computers It can be used to block incoming surges, and can also be used in power supplies that supply power.

그런데 이러한 써지차단회로를 갖는 일반적인 전원공급기는 전원단자로부터 유입된 전압의 써지를 차단하는 것은 가능하지만, 유입된 전압을 조절할 수는 없어서, 유입된 전압과는 다른 전원전압을 사용하는 전기기기에는 이용할 수 없다는 문제점이 있었다.However, a general power supply having such a surge blocking circuit can block the surge of the voltage introduced from the power supply terminal, but cannot control the voltage supplied, so it can be used for an electric device that uses a different power voltage than the input voltage. There was a problem that can not.

이에 본 발명의 목적은 전원단자로부터 유입된 전압에서 써지를 차단함은 물론, 써지가 차단된 전압이 사용자가 설정한 전압이 되도록 자동조절 하는 써지차단기능을 구비한 전원공급기를 제공함에 있다.Accordingly, an object of the present invention is to provide a power supply having a surge interruption function that automatically blocks the surge from the voltage introduced from the power supply terminal, and automatically adjusts the voltage at which the surge is interrupted to a voltage set by the user.

The surge filter unit 100 is connected in parallel to the power supply terminal, and is composed of a plurality of metal oxide varistor (100a) as shown in Figure 3, through which the surge is grounded and blocked.

유도성 소자인 코일과 용량성 소자인 콘덴서로 구성된 상기 제1 노이즈필터부(110)는 상기 써지필터부(100)를 통해 써지가 차단된 전압에 포함된 노이즈를 차단한다.The first noise filter 110 including a coil as an inductive element and a capacitor as a capacitive element blocks noise included in a voltage from which surge is blocked through the surge filter 100.

상기 제어부(120a)는 상기 써지필터부(100)와 상기 제1 노이즈필터부(110)를 통해 써지와 노이즈가 차단된 전압이 사용자가 설정한 전압이 되도록 제어하는 제어신호를 출력한다. 이러한 제어신호는 후술하는 전압설정부(150)를 통해 사용자가 설정한 전압에 따른 펄스폭변조방식의 제어신호로서, 전압자동조절부(120b)로 출력된다.The control unit 120a outputs a control signal through the surge filter unit 100 and the first noise filter unit 110 to control a voltage from which surge and noise are blocked to be a voltage set by a user. The control signal is a control signal of the pulse width modulation method according to the voltage set by the user through the voltage setting unit 150 to be described later, is output to the voltage automatic control unit 120b.

상기 전압자동조절부(120b)는 상기 제어부(120a)의 제어신호에 따라 스위칭되어 전원단자로부터 유입된 전압을 조절한다.The voltage automatic controller 120b is switched according to the control signal of the controller 120a to adjust the voltage introduced from the power terminal.

그리고 상기 전압변환부(120c)는 1차측 코일과 2차측 코일을 포함하는 일반적인 변압기 형태일 수가 있어서, 상기 전압자동조절부(120b)를 통해 조절된 전압이 최종적으로 사용자가 설정한 전압이 되도록 한다.The voltage converter 120c may be in the form of a general transformer including a primary coil and a secondary coil, so that the voltage adjusted through the voltage automatic controller 120b is finally set by a user. .

상기 제2 노이즈필터부(130)는 상기 전압자동조절부(120b)와 상기 전압변환부(120c)를 통해 조절된 전압에 포함된 노이즈를 차단한다.The second noise filter 130 blocks noise included in the voltage adjusted by the voltage automatic controller 120b and the voltage converter 120c.

상기 표시부(140)는 각 단계별 보호상태를 표시하는 것으로서, LED램프 또는 LCD 등으로 구현가능한데, 예를 들면, 써지가 차단되었을 때나 노이즈가 차단되었을 때 등의 상태를 LED램프를 온(ON)/오프(OFF) 함으로서, 외부에서 용이하게 전원공급기의 상태를 확인할 수 있게 한다. 그리고 전원공급기에 더 포함될 수 있는 써지카운터에 의해 카운트 된 써지유입횟수 등을 LCD에 숫자로 표시할 수도 있다.The display unit 140 displays the protection status for each step, and may be implemented as an LED lamp or an LCD. For example, when the surge is blocked or noise is blocked, the LED lamp is turned on / off. By turning off, it is possible to easily check the status of the power supply from the outside. In addition, the number of surge inflows counted by the surge counter, which may be further included in the power supply, may be displayed as a number on the LCD.

또한, 이러한 표시부(140)를 통해 입력전압과 출력전압을 표시할 수가 있어서, 사용자는 이를 확인하고 후술하는 전압설정부(150)를 조작하여 최종적으로 출력하고자 하는 전압을 설정할 수가 있다.In addition, since the input voltage and the output voltage can be displayed through the display unit 140, the user can set the voltage to be finally output by confirming this and manipulating the voltage setting unit 150 to be described later.

한편, 상기 전압설정부(150)는 전원단자로부터 유입된 전압이 사용자가 설정한 전압이 되도록 하기 위해 사용자가 전압을 설정하는 것으로서, 스위치 형태일 수가 있다.On the other hand, the voltage setting unit 150 as the user sets the voltage so that the voltage introduced from the power supply terminal is set by the user, it may be in the form of a switch.

이하 상술한 구성을 가지는 써지차단기능을 구비한 전원공급기에 대한 전체적인 회로와 각 단계별 교류전압의 파형을 첨부도면을 참조하여 설명하기로 한다.Hereinafter, the overall circuit and the waveform of the AC voltage for each stage of the power supply having the surge blocking function having the above-described configuration will be described with reference to the accompanying drawings.

도 3은 본 발명의 실시예에 따른 써지차단기능을 구비한 전원공급기의 회로도를 도시한 것이고, 도 4a 내지 도 4e 는 본 발명의 실시예에 따른 전압공급기내에서 각 단계별 교류전압파형을 도시한 것이다.Figure 3 shows a circuit diagram of a power supply having a surge interruption function according to an embodiment of the present invention, Figures 4a to 4e shows the AC voltage waveform for each step in the voltage supply according to an embodiment of the present invention will be.
