본 고안은 교류 부하 제어장치에 관한 것이며, 특히 직류 제어신호로서 교류 부하를 제어하기 위한 제어장치에 관한 것이다.The present invention relates to an AC load control device, and more particularly, to a control device for controlling an AC load as a DC control signal.

종래에 있어서는 직류 제어 신호로서 교류 부하를 제어하기 위한 장치로서 직류 계전기를 주로 사용하였었다. 이렇게 계전기를 사용하는 제어장치는 계전기의 기계적 동작에 의한 것이므로 아무래도 그 수명이 제한되고 또한 계전기의 직류 구동부를 설계함에 있어 그 가격이 고가가 됨을 회피할 수 없었다. 따라서 제품 전체의 신뢰성이 저하되고 그 제어장치의 적용 개소가 제한되는 것이다.In the past, a DC relay was mainly used as a device for controlling an AC load as a DC control signal. Since the control device using the relay is due to the mechanical operation of the relay, its life is limited and it is inevitable that the price is high in designing the DC drive unit of the relay. Therefore, the reliability of the whole product falls and the application location of the control apparatus is restrict | limited.

본 고안의 목적은 기계적인 작동을 하는 계전기를 사용하지 않음으로써 그 수명을반영구적으로 하여 신뢰성을 높임과 동시에 구동부 가격이 저렴한 교류 부하 제어장치를 제공하는데 있다.It is an object of the present invention to provide an AC load control device having a low driving part price while increasing reliability by semi-permanently extending its life by not using a mechanically operated relay.

이하 첨부된 도면을 참조하면서 본 고안의 양호한 실시예로서 초음파 가습장치를 예로들어 본 고안의 특징 및 장점을 더욱 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the ultrasonic humidification device as a preferred embodiment of the present invention will be described in more detail the features and advantages of the present invention.

제1도에서는 브리지 다이오드(21)의 C점을 NPN 트랜지스터(23)의 콜랙터에 연결하고, 트랜지스터(23)의 베이스와 콜랙터 사이에는 초음파 발생용 수정 발진자(26)를 접속하고 베이스와 에미터 사이에는 콘덴서(28)을 연결하였다.In FIG. 1, the point C of the bridge diode 21 is connected to the collector of the NPN transistor 23, and the crystal oscillator 26 for ultrasonic generation is connected between the base and the collector of the transistor 23, and the base and the emi The capacitor 28 was connected between the electrodes.

여기에서 트랜지스터(23), 초음파 발생용 수정 발진자(26), 콘덴서(22, 27, 28), 저항(29, 31) 및 인덕턴스(24, 25)로 구성된 발진회로는 수조내의 물을 무화시키기 위한 것으로 실용신안공고 제83-663호 "초음파 무화유니트'에서 이미 공고된 것이므로 자세한 설명은 그 내용을 참조하면 된다. 또한, 단자(A, B)사이에는 교류부하(M)에 가해질 교류 전력원이 연결된다.Here, the oscillation circuit composed of the transistor 23, the crystal oscillator 26 for generating ultrasonic waves, the capacitors 22, 27, 28, the resistors 29, 31, and the inductances 24, 25 is used for atomizing the water in the tank. Since it was already announced in Utility Model Publication No. 83-663, "Ultrasonic Atomization Unit," refer to the description for details. In addition, an AC power source to be applied to the AC load M is provided between the terminals A and B. Connected.

따라서 단자(A)가 (+)이고 단자(B)가 (-)인 경우와, 단자(A)가 (-)이고, 단자(B)가 (+)인 경우의 두가지로 나누어 생각할 수 있다.Therefore, it is conceivable to divide into two cases where the terminal A is positive and the terminal B is negative, and the terminal A is negative and the terminal B is positive.

또한, 교류부하(M)의 일단에는 다이오드(D1~D4)로 구성된 브리지 회로의 E점이 연결되고 브리지 회로의 H점은 단자(B)에 연결됨과 동시에 부하(M)의 타단은 단자(A)에 연결된다.In addition, E point of the bridge circuit composed of diodes D 1 to D 4 is connected to one end of the AC load M, H point of the bridge circuit is connected to the terminal B, and the other end of the load M is connected to the terminal ( Connected to A).

브리지 회로의 F 점과 G 점 사이에는 SCR의 에노드와 캐스우드를 연결한다. SCR의 게이트는 저항(R2)를 통하여 콘덴서(C1)의 일단에 연결하고 콘덴서(C1)의 타단은 SCR의 캐스우드 전극에 연결된다.Connect the SCR's anode and caswood between the F and G points of the bridge circuit. The gate of the SCR is connected to one end of the capacitor C 1 through the resistor R 2 and the other end of the capacitor C 1 is connected to the caswood electrode of the SCR.

먼저 단자(A)가 (+)이고 단자 (B)가 (-)인 경우를 설명하겠다.First, the case where terminal A is positive and terminal B is negative will be described.

리드 스위치를 접속하면 전류는 다이오드 브리지(21)의 다이오드(21B)를 통하여 리드 스위치(SW1)를 거쳐 다이오드(D5) 및 저항(R1및 R2)를 거쳐 SCR의 게이트 단자에 인가된다. 또한, 단자(B)의 (-) 전위는 다이오드(D4)를 통하여 SCR의 캐스우드 단자와 콘덴서(C1)의 일단에 인가된다.When the reed switch is connected, current is applied to the gate terminal of the SCR via the reed switch SW 1 through the diode 21B of the diode bridge 21 via the diode D 5 and the resistors R 1 and R 2 . . In addition, the negative potential of the terminal B is applied to the caswood terminal of the SCR and one end of the capacitor C 1 via the diode D 4 .

따라서 단자(A)가 (+)극성이고 단자(B)가 (-)극성인 동안 콘덴서(C1)은 충전되고 단자(A, B)의 전위극성이 바뀌일 동안에는 콘덴서(C1)에 충전되었던 전하가 SCR의 작동 전압을 유지시켜주므로 교류부하(M)이 연속 작동하게 된다. SCR이 도통되면 교류부하의 구동전압은 단자(A)가 (+)극성이고 단자(B)가 (-)극성인 경우 단자(A)→교류부하(M)→다이오드(D1)→SCR→다이오드(D4)→단자(B)의 경로를 통하여 인가되고 단자(A)가 (-)극성이고 단자(B)가 (+)극성인 경우에는 단자(A)→교류부하(M)→다이오드(D3)→SCR→다이오드(D2)→단자(B)의 경로를 통하여 인가되므로 교류부하(M)이 작동되는 것이다.Therefore, the terminal (A) is a (+) polarity and the terminal (B) the (-) polarity of the capacitor (C 1) is charged to a long one charged and the change in the potential polarity of the terminals (A, B) a capacitor (C 1) for Since the charged charge maintains the operating voltage of the SCR, the AC load M is continuously operated. When SCR is conducting, the driving voltage of AC load is the terminal (A) → AC load (M) → diode (D 1 ) → SCR → when terminal (A) is positive and terminal (B) is negative. When diode (D 4 ) is applied through the path of terminal (B), and terminal (A) is negative and terminal (B) is positive, terminal (A) → AC load (M) → diode (D 3 ) → SCR → Diode (D 2 ) → It is applied through the path of terminal (B), so the AC load (M) is activated.

제2도에서는 본 고안에 의한 다른 제어장치가 도시되 어있는데 이 역시 초음파 가습기의 교류부하 제어장치의 일예로서 여기에서는 제1도의 다이오드(D1~D4) 및 SCR을 트라이악 소자로 대체한 것이다. 여기에서는 브리지 다이오드(21)의 단자(C)를 PNP트랜지스터(Q1)의 에미터에 접속하고 트랜지스터(Q1)의 베이스와 저어부 출력단자 사이에 저항(R4)을 접속하고 트랜지스터(Q1)의 콜랙터는 다이오드(D5)와 저항(R1, R2)을 통하여 트라이악의 게이트 단자에 연결시킨다.2 shows another control device according to the present invention, which is also an example of an AC load control device of an ultrasonic humidifier, in which the diodes D 1 to D 4 and SCR of FIG. 1 are replaced with triac elements. will be. Here, the terminal C of the bridge diode 21 is connected to the emitter of the PNP transistor Q 1 , the resistor R 4 is connected between the base of the transistor Q 1 and the bottom output terminal, and the transistor Q The collector of 1 ) is connected to the triac's gate terminal via diode D 5 and resistors R 1 and R 2 .

저항(R1)과 저항(R2)의 접속점에 콘덴서(C1)의 일단을 연결하고 콘덴서(C1)의 타단을 단자(B)에 연결시키며 단자(B)에는 트라이악의 단자(T1)와 다이오드(21D)와 다이오드(21C)의 접점을 연결시킨다.Connect one end of the capacitor (C 1 ) to the connection point of the resistor (R 1 ) and the resistor (R 2 ), connect the other end of the capacitor (C 1 ) to the terminal (B), and the terminal (B) of the triac terminal (T 1) ) And the contact of the diode 21D and the diode 21C.

이와같이 구성된 회로의 동작을 설명하면, 우선 전술한 공지의 회로의 일부인 제어부의 출력단자에서는 통상과 같이 저레벨 또는 고레벨의 제어 전압이 출력된다. 만일 제어부의 출력단자에 저레벨 전압의 출력이 발생될 경우 저항(R3)와 저항(R4)을 통하여 단자(A)에서 전류가 흐르게 되어 트랜지스터(Q1)의 베이스에 바이어스 전압을 가하게 되어 트랜지스터(Q1)가 도통한다.Referring to the operation of the circuit configured as described above, first, the output terminal of the control unit which is a part of the above-described known circuit is outputted with the low or high level control voltage as usual. If the output of the low level voltage is generated at the output terminal of the controller, a current flows in the terminal A through the resistor R 3 and the resistor R 4 to apply a bias voltage to the base of the transistor Q 1 . (Q 1 ) is conducting.

따라서 단자(A)가 (+)이고 단자(B)가 (-)극성일 때에는 전류가 단자(A)→ 다이오드(21B)→트랜지스터(Q1)→다이오드(D5)→저항(R1)→저항(R2)의 경로를 거쳐 트라이악의 게이트 단자에 인가되며 동시에 콘덴서(C1)를 충전하게 된다. 만약, 교류 전원이 6OHZ이면 1초에 60번동안 소정 전압으로 콘덴서(C1)를 충전시킨다. 따라서 콘덴서(C1)에 충전된 전압이 방전되면서 트라이악이 도통되어서 교류부하(M)에는 구동교류 전압이 인가되어 구동이 시작된다.Therefore, when terminal A is positive and terminal B is negative, the current is terminal A → diode 21B → transistor Q 1 → diode D 5 → resistance R 1 . → it is applied to the gate terminal of the triac via the path of resistor R 2 and simultaneously charges the capacitor C 1 . If the AC power supply is 6OHZ, the capacitor C 1 is charged to a predetermined voltage for 60 times per second. Therefore, as the voltage charged in the capacitor C 1 is discharged, the triac conducts, and a drive AC voltage is applied to the AC load M to start driving.

이때에는 트라이악을 도통시키는 데에는 충분하게 콘덴서(C1)가 충전되어 있으므로 단자(A, B)의 극성에는 관계 없게 된다.At this time, since the capacitor C 1 is sufficiently charged to conduct the triac, the polarity of the terminals A and B is irrelevant.

반대로 만일 공지의 제어부 출력 단자에 고레벨의 출력신호가 나타나면 트랜지스터(Q1)의 바이어스 전압이 없어지므로 트랜지스터(Q1)가 비도통되고 따라서 콘덴서(C1)를 충전하는 전압이 없어지므로 트라이악이 비도통되어 교류부하(M)에는 구동 교류 전류가 흐르지 않게 되어 정지 상태가 된다.Conversely if this not so a transistor (Q 1) the bias voltage that appears transistor (Q 1) the high level of the output signal to a known control unit outputs a non-conductive and therefore do not have a voltage to charge the capacitor (C 1) Since the triac Non-conduction, drive AC current does not flow to AC load M, and it becomes a stop state.

이상에서 설명된 바와같이 본 고안에 따르면 계전기를 사용하지 않고 반도체 소자를 통하여 교류 전류 및 고류 부하를 제어할 수 있는 것으로서 그 수명이 거의 영구적이 되며 또한 그 생산 단가가 낮추어질 수 있는 것이므로 신뢰성이 향상되고 적용개소의 제한성이 거의 없어지는 것이다.As described above, according to the present invention, it is possible to control the alternating current and the high current load through the semiconductor element without using the relay, and the life is almost permanent and the production cost can be lowered, thereby improving reliability. And the limitation of the application point is almost eliminated.

본 고안의 실시예를 참조하여 본 고안이 설명되었으나 본 고안이 여기에 국한되는 것이 아니며, 본 고안의 정신에서 벗어나지 않는 한 많은 변형, 변경이 가능한 것이다. 예를 들자면 트랜지스터의 극성 종류의 변화(NPN에서 PNP 또는 PNP에서 NPN)는 극히 용이하게 될 수 있는 것이다.Although the present invention has been described with reference to the embodiments of the present invention, the present invention is not limited thereto, and many variations and modifications are possible without departing from the spirit of the present invention. For example, a change in the polarity type of the transistor (NPN to PNP or PNP to NPN) can be made extremely easy.
