This non-linear capacitor was developed by TDK Electronic Co., Itd. (Tokyo Electronics Co., Ltd.), and uses a polycrystal of BaTiO 3 to obtain a desired non-linear.
이것에 대해서는 "Journal Electronic Engineering"의 march 80, 제20페이지에 간단히 소개되어 있다.This is briefly introduced in march 80, page 20 of "Journal Electronic Engineering".
비직선성콘덴서와 반도체스위치를 사용한 방전등용점등장치의 종래 회로예를 제1도에 나타내고 있지만 이와 같은 회로에 의하면 순시점등(時點燈)이 실현된다.An example of a conventional circuit of a discharge lamp for a discharge lamp using a nonlinear capacitor and a semiconductor switch is shown in FIG. 1, but according to such a circuit, an instantaneous Time is realized.
제1도에 있어서 (1)은 형광램프, (2)는 유도성안정기, (3)은 반도체스위치로서의 쌍방향성(雙方向性) 2단자 다이리스터(Silicon Symmet-rical Switch SSS), (4), (5)는 다이오우드, (6)은 저항, (7)은 비직선성 콘덴서, U, V는 전원단자를 나타낸다. 제2도는 제1도에 나타낸 회로의 회로동작을 설명하기 위한 램프(1)양단사이의 전압파형도이다.In FIG. 1, (1) is a fluorescent lamp, (2) is an inductive ballast, (3) is a bidirectional two-terminal thyristors as a semiconductor switch, (4) (5) represents diodes, (6) represents resistors, (7) represents nonlinear capacitors, and U and V represent power terminals. FIG. 2 is a voltage waveform diagram between both ends of the lamp 1 for explaining the circuit operation of the circuit shown in FIG.
제1도의 회로에 있어서, 전원단자 U-V사이에 교류전압θ를 제2도의 점선파형과 같이 인가한다. 기동초기(起動初期)에 있어서는 전원전압 θ가 2단자 다이리스터(3)의 브레이크오우버전압에 달하면(위상) 2단자 다이리스터(3)는 터언온(turn-on)하고, 안정기(2)를 통해서 램프릴라멘트(filament of lamp)를 예열(豫熱)하는 전류가 흐른다. 예열전류가 흐른후, 위상 θ2에서 예열전류가 0으로되어 2단자 다이리스터(3)는 터언오프한다. 이때 콘덴서(7)의 전압이 0이며, 전원전압 θ가 부(負)의 파고치(波高値)근방에 있으므로, 안정기(2)를 통해서 콘덴서(7)가 도시극성(圖示極性)에 충전되다. 여기서 콘덴서(7)는 그 전압 V와 전하 Q와의 관계가 제3도와 같이 가포화특성(可飽和特性)을 지니고 있으므로 전원전압파고치 이하에서 비직선 영역에 들어가도록 콘덴서특성을 선정하면 콘덴서(7)로의 충전전류는 급감하고 또한 안정기(2)에 유도성 안정기를 병용하고 있으므로, 콘덴서(7)의 충전전압은 급상승하여, 제2도 V1에서 나타낸 바와 같은 전원전압파고치보다도 훨씬 높은 펄스상 전압으로 되어서, 램프(1)에 인가된다.In the circuit of FIG. 1, an alternating voltage [theta] is applied between the power supply terminals UV as in the dotted line waveform of FIG. In the start-up phase, when the power supply voltage θ reaches the brake over voltage of the two-terminal die Lister 3 (phase), the two-terminal die lister 3 is turned on and the ballast 2 Through the current to preheat the lamp filament (filament of lamp) flows. After the preheating current flows, the preheating current becomes zero in phase θ 2 and the two-terminal die Lister 3 is turned off. At this time, since the voltage of the capacitor 7 is 0 and the power supply voltage θ is near the negative crest value, the capacitor 7 is charged to the city polarity through the ballast 2. become. In this case, the capacitor 7 has a saturation characteristic as shown in Fig. 3 because the relationship between the voltage V and the charge Q is such that when the capacitor characteristic is selected to enter the non-linear region below the power supply voltage peak value, the capacitor 7 ), the charge current is plunged and also because the combined use of an inductive ballast to the ballast (2), the charging voltage of the capacitor 7 is rising, the second is much higher pulse phase than the value, coming as a power supply voltage indicated at V 1 to The voltage is applied to the lamp 1.
펼스발생후는 2단자 다이리스터(3)가 재차 터언오프할 때까지 전원전압가 인가된다. 이후, 램프(1)가 점등(點燈)하는 램프전압은 전원전압보다도 내려가므로, 저항(6)의 작용으로 정방향(正方向)의 램프전압에 의한 콘덴서(7)에의 충전전류는 억제되며, 정방향의 램프전압은 2단자 다이리스터(3)의 브레이크오우 버전압이하로 되어 램프는 안정된 방전을 지속한다. 이때 부방향의 랭프전압에 의해 다이오우드(5)를 통해서 콘덴서(7)는 도시극성에 충전됨으로써 랭프전압은 높아지지만(V2), 다이오우드(4)의 작용으로 램프는 방전을 지속한다.After the pull occurs, the power supply voltage is applied until the two-terminal die Lister 3 turns off again. Thereafter, since the lamp voltage at which the lamp 1 is turned on is lower than the power supply voltage, the charging current to the capacitor 7 due to the positive lamp voltage is suppressed by the action of the resistor 6, The ramp voltage in the forward direction becomes equal to or lower than the break-off version pressure of the two-terminal die Lister 3, so that the lamp continues stable discharge. At this time, the capacitor 7 is charged to the city polarity through the diode 5 by the negative voltage in the negative direction, so that the voltage is increased (V 2 ), but the lamp continues to discharge due to the action of the diode 4.
이상의 설명에서 명백하듯이, 2단자 다이리스터(3) 브레이크우버전압 VBO(이하 단지 VBO라고 약칭함)는 방전후의 램프전압 V3보다도 높고, 전원전압파고치 V4보다도 낮지 않으면 안되지만 지나치게 높게 파고치 V4에 가까와지면 2단자 다이리스터(3)의 점호위상(點弧位相) θ1이 늦어져 예열전류가 적어진다. 이 때문에 실제로 2단자 다이리스터(3)에 요구되는 VBO의 폭은 V3~V4보다도 더욱 좁은 것으로 되며, 공업적으로 그와 같은 VBO폭이 좁은 것을 얻는 일은 매우 비싸게 먹혀, 따라서 이 다이리스터(3)를 사용한 방전등점등장치고 비싸게 먹히는 결점이 있다.As is clear from the above description, the two-terminal thyristor 3 brake uber voltage V BO (hereinafter simply abbreviated as V BO ) is higher than the lamp voltage V 3 after discharge and must be lower than the power voltage peak value V 4 , but excessively. becomes higher peak-value delay the firing phase (點弧位相) θ 1 of the approaches when two-terminal thyristor 3 to V 4, the less the pre-heating current. For this reason, the width of V BO actually required for the two-terminal die Lister 3 becomes narrower than that of V 3 to V 4 , and it is very expensive to obtain such a narrow V BO width industrially. Discharge lamps using the Lister 3 have a disadvantage of being expensive.
본원 고안은 상기 결점을 고안해서 이루어진 것으로, 방전관(放電)에 별렬로 접속된 비직선성콘덴서를 갖는 것에 있어서, 그 비직선성콘덴서와 직렬로 제너다이오우드를 접속하고, 2단자 다이리스터의 VBO의 폭을 넓게 선정할 수 있으며, 그 때문에 다이리스터의 생산원가를 내릴 수 있기 때문에 회로의 생산원가를 저감시킨 방전등점등장치를 제공하는 것이다.The present invention is made by devising the above drawbacks, and the discharge tube In the case of having a non-linear capacitor connected in parallel to the non-linear capacitor, a zener diode can be connected in series with the non-linear capacitor, and the width of the V BO of the two-terminal die Lister can be widened. Since the production cost can be lowered, it is to provide a discharge lamp that reduces the production cost of the circuit.
제4도는 본원 고안의 실시예도면이며, 제5도는 본원 고안을 설명하기 위한 램프양단간 전압파형도이다.4 is an exemplary diagram of the present invention, and FIG. 5 is a voltage waveform diagram between both ends of the lamp for explaining the present invention.
다음에 제4도에 의하여 본원 고안의 실시예에 대해서 설명하면 (1)(4) 및 (7)은 제1도에 나타낸 것과 동일하거나 또는 해당부분을 나타내고 있다. (8)은 제너다이오우드이다. 이와 같이 구성된 회로에 있어서 기동처기에 있어서 전원전압 θ가 투입되면, 위상 θ0에 있어서 콘덴서(7)에 인가되는 전압은 제너다이오우드(8)의 제너전압을 V2라고 하면(θ0-V2)이다. 여기에 이 값을 콘덴서(7)가 비직선영역에 들어가는 전압 이상으로 선정해 놓으면, 전원파고치보다도 높은 전압이 위상θ0에서 램프당단에 나타나므로 단자 다이리스터(3)는 터언온하고 예열전류가 흐르기 시작한다. 램프점등후는 콘덴서(7)에는 램프전압을 VL이라고 하면 (VL-V2)의 전압이 정방향에 인가되지만 이 전압이 낮은 값이기 때문에 콘덴서(7)에의 충전전류는 억제되며 2단자 다이리스터(3)의 브레이크오루버전압이하로 되어 안정된 방전을 지속한다.Next, an embodiment of the present invention will be described with reference to FIG. 4, and (1) (4) and (7) show the same or corresponding parts as shown in FIG. (8) is Zener diode. In the circuit configured as described above, when the power supply voltage θ is applied at the start-up stage, the voltage applied to the capacitor 7 in the phase θ 0 is assumed to be the zener voltage of the zener diode 8 as V 2 (θ 0 -V 2). )to be. If this value is set above the voltage at which the capacitor 7 enters the non-linear region, the voltage higher than the power peak value appears at the end of the lamp at the phase θ 0 , so that the terminal thyristor 3 is turned on and the preheating current. Begins to flow. After the lamp is turned on, if the lamp voltage is set to VL in the capacitor 7, the voltage of (VL-V 2 ) is applied in the forward direction, but since the voltage is low, the charging current to the capacitor 7 is suppressed and the two-terminal thyristor ( The brake overpressure voltage of 3) is lowered to maintain stable discharge.
즉, 2단자 다이리스터(3)의 브레이크오우버전압 VBO가 전원전압 이상에서도 제너다이오우드(8)의 작용에 의해 2단자 다이리스터(3)는 충분히 터언온할 수 있으며, 더구나 그 점호위상 θ0은 전원전압파고치 위상보다도 훨씬 빠르게 할수 있다.That is, even if the brake overvoltage V BO of the two-terminal die Lister 3 is equal to or higher than the power supply voltage, the two-terminal die Lister 3 can be sufficiently turned on by the action of the Zener diode 8, and the firing phase θ Zero can be much faster than the supply voltage peak phase.
한편, 제1도에 나타낸 종래예에 있어서는 2단자 다이리스터(3)를 브레이크오우버시키는데 필요한 정방향전압을 얻기 위해, 저항(6)의 값을 적당히 설정하면, 콘덴서(7)에 의한 전압(V0)이 발생하지만, 이 전압은 저항(6)의 한류작용(限流作用)때문에, 본원 발명에 제4도의 것에 비해 낮은 값으로 되어 2단자 다이리스터(3)의 허용 VBO의 폭을 넓히는 것은 대폭적으로는 할 수 없다.On the other hand, in the conventional example shown in FIG. 1, when the value of the resistor 6 is appropriately set in order to obtain the forward voltage required for the brake offover of the two-terminal die Lister 3, the voltage V of the capacitor 7 0 ) occurs, but this voltage is lower than that of FIG. 4 in the present invention due to the current-limiting action of the resistor 6, thereby widening the width of the allowable V BO of the two-terminal thyristor 3. It can't be done drastically.
즉 본원 고안에 의하면 예열특성을 해침이 없이 폭이 넓은 Vbo를 갖는 2단자 다이리스터를 채용할 수 있고, 공업적으로 매우 유리한 동시에 염가의 방전등점등장치를 제공할 수 있는 이점이 있다.That is, according to the present invention, a two-terminal thyristor having a wide V bo without preheating characteristics can be adopted, and there is an advantage in that it is very advantageous industrially and can provide an inexpensive discharge lighting device.
그리고 본 실시예에서는 다이리스터에 2단자 다이리스터에서 설명했지만 PNPN스위치등의 역저지(逆止) 2단자 다이리스터로도 똑같은 효과를 거두는 것은 물론이다.In the present embodiment, the two-terminal thyristors are described in the thyristors. 止) Of course, the same effect can be achieved with the two-terminal thyristors.
