최근 전자식 형광등 안정기와 네온 할로겐 안정기둥이 있었으나 종래의 기계식 안정기에 비해 내구성이나 전기적 특성이 크게 좋지 못하여 대량 보급이 되지 않아 에너지 절약에 크게 기여하지 못하는 실정이었던 것이다.Recently, there was an electronic fluorescent ballast and a neon halogen ballast, but the durability and electrical properties are not very good compared to the conventional mechanical ballast, so that the situation is not a large contribution to energy saving because it is not widely distributed.
이에 본 발명은 무부하 상태나 부하의 조건에 상관없이 뛰어난 절전효과를 가지며 높은 신뢰성으로 제품의 수명을 연장시키며 내구성 또한 크고 선로 및 변압기의 손실을 최대한 줄일 수 있도록 고역률 방식을 사용하여 안정기 전원 입력단에 특수 고조파회로를 사용하여 고조파 함유율은 기존의 코일식 안정기 보다 낮아 정밀 기계가 설치된 장소에도 사용이 가능하며 전자파 제거회로를 사용함으로서 고조파 잡음이 낮아 주변기기의 작동에도 지장이 없으며 입력단에 서지(surge) 필터에 의하여 서지를 완벽하게 차단함으로 2차측 안정기 내부에 파손이 없으며 전압변동에 따라 발진주파수 불안정으로 생기는 문제점을 해결하기 위하여 정전압회로를 사용하였으며 발진주파수를 변화시켜 출력신호폭을 가변함으로서 부하의 정류에 따라 출력전압을 조절할 수 있어 형광등의 조도조정이 가능하여 전력소모를 최대한 줄이는 인버터를 제공하는데 본 발명의 목적이 있는 것이다. 이와 같은 목적을 가진 본 발명의 구성을 이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention has an excellent power saving effect regardless of the no-load condition or load conditions, and extends the life of the product with high reliability, and it is also durable and uses a high power factor method to reduce the loss of lines and transformers. Harmonic content is lower than conventional coil type ballast by using special harmonic circuit, so it can be used in the place where precision machine is installed. The surge is completely blocked to prevent damage inside the secondary ballast and the constant voltage circuit is used to solve the problem caused by the oscillation frequency instability due to the voltage fluctuation. According to the output voltage It is an object of the present invention to provide an inverter that can be adjusted to reduce the power consumption as possible by adjusting the illumination of the fluorescent lamp.

상기와 같은 구성으로 이루어진 본 발명의 작용 및 효과를 자세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration in detail as follows.
제1도는 본 발명의 블록도로서 입력단에 교류(AC)전압이 인가되면 서지피터(1)와 전자파 및 고조파 제거회로(2)를 거쳐 콘버터 전원변환부(3)에서 정류된 전압을 역률보상회로(4')에서 역상차 보상을 이루어 고역률을 만들고 정류된 직류(DC) 고전압을 정전압회로(4'')를 사용하여 발진부(5)의 입력변동에 관계없이 일정한 전압을 인가하므로 발진부(5)가 동작되게 하여 스위칭부(6)를 구동시켜 출력시키고 출력에 발생하는 전압을 출력전류조정부(7)를 거쳐 안정된 출력 전압이 부하(8)에 공급되게 된다.FIG. 1 is a block diagram of the present invention, when an AC voltage is applied to an input terminal, the power factor correction circuit converts the voltage rectified by the converter power converter 3 through the surge Peter 1 and the electromagnetic and harmonic rejection circuit 2. (4 ') the reverse phase compensation to make a high power factor and by applying a constant voltage regardless of the input variation of the oscillator (5) using the rectified direct current (DC) high voltage using a constant voltage circuit (4' ') oscillator (5) ) Is operated so that the switching unit 6 is driven and output, and a stable output voltage is supplied to the load 8 via the output current adjusting unit 7.
또한 부하가 연결되어 있지 않을 경우나 과부하시 과전압 전류검출부(9)가 작동하여 발진부(5)의 출력신호를 홀딩(holding)하므로서 스위칭부(6)의 온(ON) 오프(OFF)동작이 중지됨에 따라 출력전압이 발생하지 않아 기기의 손상을 막아줄 뿐만 아니라 화재의 예방에도 도움이 크다.In addition, when the load is not connected or during overload, the overvoltage current detection unit 9 operates to hold the output signal of the oscillator 5, thereby stopping the ON / OFF operation of the switching unit 6. As it does not generate output voltage, it not only prevents damage to the device but also helps to prevent fire.
제2도는 본 발명의 회로도로서 회로도에 의한 동작 상태를 상세히 설명하면 다음과 같다.2 is a circuit diagram of the present invention, when the operation state according to the circuit diagram in detail as follows.
먼저 입력단에 교류 (AC)전압이 인가되면 서지필터(1)의 바이메탈(CB)과 퓨즈(F1)를 통해 서지제어소자(TNR1)의 과도파형으로 유기되어 전자파 및 고조파 제거회로(2)의 트랜스(T1)와 콘덴서(C1)에 콘버터전원변환부(3)에 의해 직류(DC)전압으로 정류되어 열률보상회로(4')의 콘덴서(C2)와 트랜스(T2) 및 콘덴서(C3)로서 고역률로 보상되어 스위칭부(6)의 전계효과 트랜지스터(FET1)(FET2)로 전송됨과 동시에 정전압회로(4'')의 트랜지스터(TR1)(TR2)와 저항(R1)(R2)의 분압에 의해 발진부(5) 내에 정전압이 공급되면 가변저항(VR)과 콘덴서(C5)로 설정된 주기의 펄스를 출력시키며 콘덴서(C6)(C7)를 통해 스위칭부(6)의 트랜스(T3)의 일차측코일에 인가됨에 따라 이차측코일에 연결된 전계효과 트랜지스터(FET1)(FET2)가 교대로 온(ON)오프(off)동작을 반복하여 출력전압이 발생하게 된다.First, when an alternating current (AC) voltage is applied to the input terminal, the bimetal CB and the fuse F 1 of the surge filter 1 are induced into the transient waveform of the surge control element TNR 1 to remove the electromagnetic wave and harmonics. The converter T 1 and the capacitor C 1 are rectified by a converter power converter 3 to a direct current (DC) voltage, and the capacitors C 2 , transformers T 2 , and The capacitor C 3 is compensated with a high power factor and is transferred to the field effect transistor FET 1 and FET 2 of the switching unit 6, and simultaneously with the transistors TR 1 and TR 2 of the constant voltage circuit 4 ″. When a constant voltage is supplied to the oscillation unit 5 by the partial pressure of the resistors R 1 and R 2 , a pulse of a period set by the variable resistor VR and the capacitor C 5 is output, and the capacitor C 6 and C 7 are output. As applied to the primary side coil of the transformer T 3 of the switching unit 6, the field effect transistors FET 1 and FET 2 connected to the secondary side coils alternately turn on and off. Repeatedly The output voltage is generated.
따라서 스위칭부(6)의 출력전압이 출력전류 조정부(7)의 콘덴서(C12)(C13)와 트랜스(T4)(T5) 및 다이오드(D6)(D7)로서 과전압과 전류를 검출하여 부하(8)에 인가하여 점등시킨다.Therefore, the output voltage of the switching unit 6 is the overvoltage and current as the capacitors C 12 (C 13 ) and the transformers T 4 (T 5 ) and the diodes D 6 (D 7 ) of the output current adjusting unit 7. Is detected and applied to the load (8) to light it.
이때 전류 조정등인 트랜스(T4)(T5)에도 전류가 유기되므로 유기된 전압을 과전압 전류검출부(9)에 피드백(peed back)시켜 분할 저항인 저항(R5)(R4)에서 분할되어 다이리스터(SCR)의 게이트(Gare)단으로 인가되나 부하(8)의 종류 및 무부하 상태에 따라 과전압 검출부(9)의 동작여부가 결정되어 출력전압은 항상 일정하게 공급된다.At this time, the current is also induced in the transformer (T 4 ) (T 5 ), which is a current adjustment lamp, so that the induced voltage is fed back to the overvoltage current detector (9) to divide the resistor (R 5 ) (R 4 ), which is a split resistor. This is applied to the gate (Gare) stage of the thyristors (SCR), but the operation of the over-voltage detector 9 is determined according to the type and the no-load state of the load 8, so that the output voltage is always supplied constantly.
만일 부하(8)가 과부하 상태이거나 무부하 상태시 전류조정등인 트랜스(T4)(T5)에 유기된 전압은 과전압 전류 검출부(9)의 저항(R5)(R4)에서 분할되어 다이리스터(SCR)의 게이트단에 인가되어 발진부(5)의 발진을 홀딩시킴으로서 발진부(5)의 동작이 중지됨과 동시에 스위칭부(6)에도 펄스를 공급하지 않게되어 출력에서는 전압을 발생시키지 못하게 되는 것이다.If the load 8 is overloaded or no-loaded, the voltage induced in the transformer T 4 (T 5 ), such as current regulation, is divided by the resistor R 5 (R 4 ) of the overvoltage current detection unit 9 and the die is divided. It is applied to the gate terminal of the Lister (SCR) to hold the oscillation of the oscillator (5) to stop the operation of the oscillator (5) and at the same time does not supply a pulse to the switching unit 6, so that no output voltage is generated. .
그러므로 과부하 및 무부하시 가동으로 출력이 차단되도록 되어 있으므로 화재를 예방할 수 있고 인명 피해나 재산의 손실을 줄일 수 있는 것이다.Therefore, the output is cut off by overload and no-load operation, which can prevent fire and reduce human injury or loss of property.
한편 발진부(5)의 가변저항(VR)을 조절할 경우 가변저항(VR)값과 콘덴서(C5)에 의해 발진시 정수가 변화되어 발진부(5)의 출력펄스폭이 변동됨에 따라 스위칭부(6)의 전계효과가 트랜지스터(FET1)(FET2)의 온(ON) 오프(off) 속도가 변화되어 출력 전류 조정부(7)의 출력전압이 다르게 출력되는 것이다.On the other hand, when the variable resistor VR of the oscillator 5 is adjusted, the constant is changed at the time of oscillation by the variable resistor VR value and the condenser C 5 so that the output pulse width of the oscillator 5 changes, so that the switching unit 6 ) Is the field effect of the transistors FET 1 (FET 2 ) is changed to the output voltage of the output current adjusting unit 7 is different.
또한 제3도는 출력전류 조정부(7)를 변화시켜 타부분에 적용할 수 있는 실시예로서 제3a도는 네온전자 안정기에 적용되는 예로서, 출력전류조정부(7)를 트랜스(T6)와 콘덴서(C17)로서 출력전류를 조정하여 콘덴서(C18-C21)와 다이오드(D8-D11)로된 버퍼(8)에 인가하여 점등트랜스(T6)를 점등시키게 되고 제3b도는 할로겐 램프 안정기의 적용예이고, 제3c도는 형광등 안정기의 적용예로서 출력전류조정부(7)에 트랜스(T8)와 콘덴서(C26)를 연결하고 버퍼(8)에는 트랜스(T8)의 이차측코일을 연결하여 출력전류를 조정할 수 있는 예이며 제3d도는 3파장 형광등 램프의 적용예이다.3 is an embodiment in which the output current adjusting unit 7 can be applied to other parts by changing the output current adjusting unit 7, and FIG. 3a is an example applied to a neon electronic ballast. The output current adjusting unit 7 includes a transformer T 6 and a capacitor ( C 17 ) by adjusting the output current and applying to the buffer 8 of the capacitors C 18 -C 21 and the diodes D 8 -D 11 to turn on the lighting transformer T 6 and FIG. 3b shows a halogen lamp. application of ballast example, and the 3c turn transformer to the output current adjustment section 7 as an application example of the fluorescent lamp ballast (T 8) and the secondary side coil of, the transformer (T 8) connected to the capacitor (C 26) and the buffer (8) 3d is an example of application of a three-wavelength fluorescent lamp.
이상에서 상술한 바와 같이 본 발명은 부하(8)의 종류에 따라 출력 전류 조정부(7)를 조정하므로 스위칭부의 전압소자인 전계효과트랜지스터(FET1)(FET2)와 발진부(5)의 가변저항(VR)을 조절하여 부하(8)의 종류에 따라 불필요한 전력소모를 감쇠시킬 수 있음은 물론 누전시 감전사고 및 화재를 예방할 수 있는 효과를 제공함으로서 신뢰성 향상을 기대할 수 있는 유용한 발명인 것이다.As described above, the present invention adjusts the output current adjusting unit 7 according to the type of the load 8, so that the variable resistors of the field effect transistors FET 1 (FET 2 ) and the oscillator 5 which are voltage elements of the switching unit. By adjusting the VR, it is possible to attenuate unnecessary power consumption according to the type of the load 8 as well as to provide an effect of preventing an electric shock accident and a fire in the event of a short-circuit.
