Description

전자회로의 써지 영향 분석방법 및 그 방법에 사용되는 써지 발생장치{Method for analysis of surge effect on electronic circuits and surge generator therefor}Method for analysis of surge effect on electronic circuits and surge generator therefor}

본 발명은 각종 전자회로에서의 써지 영향 및 써지 내력을 분석하기 위한 장치에 관한 것으로써, 특히 써지발생장치에 일반 교류전원전압을 투입하여 써지 전압을 만들어 내고 이 써지 전압을 시험대상 전자회로에 인가함으로써 그 영향 및 내력을 분석할 수 있도록 한 전자회로의 써지 영향 분석방법 및 그 방법에 사용되는 써지 발생장치에 관한 것이다.The present invention relates to a device for analyzing surge effects and surge strength in various electronic circuits. In particular, a general AC power supply voltage is applied to a surge generator to generate a surge voltage, and the surge voltage is applied to the electronic circuit under test. The present invention relates to a surge impact analysis method of an electronic circuit, and a surge generating device used in the method, by which the effect and the history can be analyzed.

각종 전자회로의 써지 내력을 측정하기 위해서는 해당 전자회로에 일정한 써지를 투입하고 그 영향을 평가하는 써지 발생 및 측정 장치를 사용한다.In order to measure the surge strength of various electronic circuits, a surge generator and measuring device that inputs a certain surge to the electronic circuit and evaluates its impact is used.

써지 발생 및 측정 장치는 상당히 고가이며 부피도 대단히 커서 휴대하기가 곤란하므로, 측정할 전자회로를 써지 측정장비가 설치된 장소로 옮겨와야만 한다. 따라서 이동이 곤란하거나 부피 및 중량이 큰 전자회로 장치인 경우 써지 측정이 매우 불편하였다.Surge generating and measuring devices are quite expensive and bulky and difficult to carry, so the electronic circuit to be measured must be moved to the location where the surge measuring equipment is installed. Therefore, the surge measurement was very inconvenient in the case of an electronic circuit device having difficulty in moving or having a large volume and weight.

이러한 기존의 써지 발생장치들은 도 1에서 나타내고 있는 바와 같이 IEEE 규격에 맞추어 표준 시험에 적용하는 써지전압으로서 1.2usec/50usec의 한가지 형태로만 제한하고 있으므로 실제 전자회로가 동작하는 가장 말단의 전원환경에서 발생되는 다양한 형태의 써지 및 임펄스 등의 노이즈를 모의할 수 없다는 단점을 가지게 된다.These existing surge generators are limited to one type of 1.2usec / 50usec as the surge voltage applied to the standard test according to the IEEE standard as shown in FIG. There is a disadvantage in that it can not simulate the noise of various types such as surge and impulse.

즉, 종래의 써지 발생장치들에서 발생되는 써지파형은 저압 배전 계통에서 발생되는 써지의 형태를 통계적인 기법을 이용하여 하나의 표준 파형으로 제시한 것이므로 저압계통에서의 써지 분석에는 적합할 수 있으나 말단의 전자회로에서의 영향 및 내력을 분석하기 위한 다양한 형태의 써지 파형을 만들어내 이를 측정대상전자회로에 적용하는 불가능하였다.That is, since the surge waveform generated in the conventional surge generators is a standard waveform of the surge generated from the low voltage distribution system using a statistical method, it may be suitable for the surge analysis in the low voltage system. It was not possible to create various types of surge waveforms to analyze the effects and strengths of the electronic circuits.

본 발명은 상기한 종래의 써지영향 분석장치의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 각종 전자회로에서의 써지 영향 및 써지 내력을 분석하기 위해 일반 교류전원을 정류하여 커패시터에 축적된 전하를 저항을 통해 방전시켜 써지 전압을 만들어 내고 이 써지 전압을 시험대상 전자회로에 인가함으로써 그 영향 및 내력을 분석할 수 있도록 한 전자회로의 써지 영향 분석방법 및 그 방법에 사용되는 써지 발생장치를 제공하는데 있다.The present invention is to solve the problems of the conventional surge effect analysis device described above, the object of the present invention is to rectify the charge accumulated in the capacitor by rectifying a general AC power source for analyzing the surge effect and surge strength in various electronic circuits To provide a surge impact analysis method of the electronic circuit and a surge generator used in the method, which can generate a surge voltage by discharging it through a resistor and apply the surge voltage to the electronic circuit under test to analyze the effect and the strength. have.

여기에서 참고되는 바와 같이, 상용전원전압부(10)의 110V, 220V, 440V 등의 입력전원전압이 써지발생장치(11)에 입력되어 여기에서 미리 프로그램된 다양한 환경 조건에 따른 전원 써지전압 및 임펄스가 발생되게 구성한다.As referred to herein, input power voltages such as 110V, 220V, 440V, etc. of the commercial power supply voltage unit 10 are input to the surge generator 11 to supply power surge voltages and impulses according to various environmental conditions pre-programmed therein. Configure to generate.

상기 써지발생장치(11)에서 발생되는 다양한 환경별 모의 써지 전압파형 및 임펄스 파형은 파형출력장치(13)를 통하여 작업자가 확인할 수 있도록 구성한다. 상기 파형출력장치는 모니터 또는 프린터 등을 포함한다.Various surge voltage waveforms and impulse waveforms generated by the environment generated by the surge generator 11 are configured to be identified by the operator through the waveform output device 13. The waveform output device includes a monitor or a printer.

상기 써지발생장치(11)에서 출력되는 써지 전압, 전류와 임펄스 파형은 시험대상 전자회로(12)에 입력되어 여기에서 시험대상 전자회로에서 나타나는 각종 써지 영향을 측정 및 분석할 수 있게 연결한다The surge voltage, current and impulse waveforms output from the surge generator 11 are input to the electronic circuit 12 under test and connected to each other so as to measure and analyze various surge effects appearing in the electronic circuit under test.

도 3은 상기 써지발생장치(11)의 구체적인 회로구성도이다.3 is a detailed circuit configuration diagram of the surge generator 11.

상기 써지발생장치(11)의 구체적인 회로구성을 보면, 상용전원전압부(10)에서 출력되는 상용전원전압(V1)은 1㎲로 장치 전원을 온/오프하는 제1스위치(U1)을 통하여 4개의 다이오드(D1~D4)로 구성된 브릿지 정류회로에 입력되게 연결하고, 상기 브릿지 정류회로에서 출력되는 직류전압은 전류제한용 저항(R4), 10㎳로 온/오프하는 충전용 제2,제5스위치(U2,U5)를 직렬로 통하여 직렬RC시정수회로를 구성하는 저항(R6) 및 콘덴서(C1)의 양단간에 인가되게 연결하고 있다.Referring to a specific circuit configuration of the surge generator 11, the commercial power supply voltage V1 output from the commercial power supply voltage unit 10 is 1 kW and the first switch U1 turns on / off the device power. It is connected to the bridge rectifier circuit composed of two diodes (D1 ~ D4), and the DC voltage output from the bridge rectifier circuit is a current limiting resistor (R4), the charging second, fifth to turn on / off 10 ㎳ The switches U2 and U5 are connected in series so as to be applied between both ends of the resistor R6 and the capacitor C1 constituting the series RC time constant circuit.

또한 상기 직렬RC시정수회로의 양단간 전압은 각각 15㎳로 온/오프하는 방전용 제3,제4스위치(U3,U4)와 저항(R1)을 통하여 저항(R2)의 양간에 나타나게 연결하고, 이 저항(R2)의 양단간 전압은 저항(R3)을 통하여 부하저항(R5)에 인가되게 연결하여 구성하고 있다.In addition, the voltage between both ends of the series RC time constant circuit is connected to appear between the resistor (R2) through the third and fourth switch (U3, U4) and the resistor (R1) for discharging on / off, respectively 15 ㎳, The voltage between both ends of the resistor R2 is connected to the load resistor R5 via the resistor R3.

상기 저항(R1,R2)은 직렬RC시정수회로의 전압을 일정한 저항 비율로 분압하기 위한 분압저항이며, 저항(R3)은 부하저항(R5)에 대한 출력 전류제한용 저항이다.The resistors R1 and R2 are voltage divider resistors for dividing the voltage of the series RC time constant circuit at a constant resistance ratio, and resistor R3 is a resistor for limiting the output current to the load resistor R5.

이와 같이 구성된 본 발명의 서지영향 분석장치의 동작 및 그를 이용한 전자회로의 써지 영향 분석방법을 설명하면 다음과 같다.Referring to the operation of the surge impact analysis apparatus of the present invention configured as described above and the surge impact analysis method of the electronic circuit using the same.

도 2 및 도 3에서, 상용전원전압부(10)의 110V, 220V, 440V 등의 입력전원전압(V1)이 써지발생장치(11)에 입력되면 여기에서는 미리 프로그램된 다양한 환경 조건에 따라 써지전압 및 임펄스를 발생한다. 이것에 의해 전원전압 말단의 써지전압성분 및 임펄스 파형이 얻어지게 되며, 이러한 써지전압 및 임펄스는 파형출력장치(13)를 통해 표시되어 출력된다.2 and 3, when the input power supply voltage V1 such as 110V, 220V, 440V, etc. of the commercial power supply voltage unit 10 is input to the surge generator 11, the surge voltage according to various environmental conditions pre-programmed here. And generates an impulse. As a result, a surge voltage component and an impulse waveform at the end of the power supply voltage are obtained, and the surge voltage and the impulse are displayed and output through the waveform output device 13.

상기 써지발생장치(11)에서는 제1스위치(U1)가 상용전원전압부의 상용전원전압(V1)을 1㎲로 온/오프하여 전원입력 과도상태를 만들면, 이때의 과도전압은 4개의 다이오드(D1~D4)가 만드는 브릿지 정류회로로 정류된후 전류제한용 저항(R4)을 거쳐 10㎳로 온/오프하는 충전용 제2,제5스위치(U2,U5)에 의해 직렬RC시정수회로의 콘덴서(C1)에 충전된다.In the surge generator 11, when the first switch U1 turns on / off the commercial power supply voltage V1 of the commercial power supply voltage to 1 를 to create a power input transient state, the transient voltages are four diodes D1. The capacitor of the series RC time constant circuit is rectified by the bridge rectifier circuit made by ˜D4), and is charged by the second and fifth switches U2 and U5 for turning on / off at 10 mA through the current limiting resistor R4. It is charged to (C1).

이렇게 콘덴서(C1)에 충전된 과도전압은 다시 각각 15㎳로 온/오프하는 방전용 제3,제4스위치(U3,U4)를 거쳐 분압용 저항(R1,R2)에 의해 분압된 후, 저항(R2)의 양간에 나타난 전압이 전류제한용 저항(R3)을 통해 부하저항(R5)에 인가된다.Thus, the transient voltage charged in the capacitor C1 is divided by the voltage dividing resistors R1 and R2 through the third and fourth switches U3 and U4 for discharging, which are turned on and off to 15 kV, respectively. The voltage shown between (R2) is applied to the load resistor (R5) through the current limiting resistor (R3).

상기 콘덴서(C1)에 축적된 전하가 직렬의 저항(R1,R2)을 통해 방전될 때, 그 방전시간은 시험대상 전자회로가 연결되어 있지 않을 경우, (R1+R2+R6)C1 으로 고정된다.When the charge accumulated in the capacitor C1 is discharged through the series resistors R1 and R2, the discharge time is fixed to (R1 + R2 + R6) C1 when the electronic circuit under test is not connected. .

이때, 방전시간은 써지전압의 주파수가 되며, 저항(R1)을 가변하여 방전시간을 조절하는 것으로 써지전압의 주파수를 변경시킬 수 있다.At this time, the discharge time is the frequency of the surge voltage, and the frequency of the surge voltage can be changed by adjusting the discharge time by varying the resistor R1.

도 4는 도 3의 저항(R1)을 10 오옴에서 100 오옴까지 변화시켰을 때, 저항(R2)의 양단에 나타나는 써지전압 파형을 나타낸 것이다.4 illustrates a surge voltage waveform that appears at both ends of the resistor R2 when the resistor R1 of FIG. 3 is changed from 10 ohms to 100 ohms.

여기에서 나타나는 것처럼, 써지전압의 형태 및 크기는 방전시간을 조절하는 저항(R1)의 가변 저항 값에 따라 변화되며, 이 때 출력단의 저항(R2) 양단간의 전압은 상기 파형출력장치(13)에 써지 전압/전류 정보로 나타나게 된다.As shown here, the shape and magnitude of the surge voltage change according to the variable resistor value of the resistor R1 for controlling the discharge time, wherein the voltage between the resistor R2 of the output terminal is applied to the waveform output device 13. Appears as surge voltage / current information.

한편, 써지발생장치(11)에 시험대상 전자회로(12)를 연결할 경우에는 방전시간이 (R1+(R2//(R3+R5)))C1의 시정수 값으로 되며, 전자회로의 입력단 임피던스가 클 경우 (R1+R2)C1 으로 계산하는 것이 가능하다.On the other hand, when the electronic circuit 12 under test is connected to the surge generator 11, the discharge time becomes the time constant value of (R1 + (R2 // (R3 + R5))) C1, and the input terminal impedance of the electronic circuit is If large, it is possible to calculate (R1 + R2) C1.
