본 고안은 정전압 안정화 회로에 관한 것으로 특히 리모콘 등, 리모콘커텐, 인체감지기, 오존 발생기 등 저용량 부하단의 정전압 회로에서 발생되는 열을 최대한 억제하여 별도로 방열판(Heat Sink)을 설치하지 않더라도 안정된 동작을 수행토록 한 것이다.The present invention relates to a constant voltage stabilization circuit, and in particular, to suppress the heat generated from the constant voltage circuit of the low-capacity load stage such as a remote control, a remote control curtain, a human body detector, and an ozone generator as much as possible to perform a stable operation even without installing a heat sink separately. It is so long.

종래에 있어, 정전압 안정화 회로는 여러가지 종류가 제안된바 있으나, 과부하시의 과열방지를 위한 수단으로서 필연적으로 방열판을 별도로 설치해야만 하므로 부품이 장착되는 공간을 많이 차지할 뿐만 아니라 제품 코스트가 상승되는 문제점이 야기되었다.In the related art, various kinds of constant voltage stabilization circuits have been proposed, but as a means for preventing overheating in case of overload, a heat sink must be separately installed, thus not only occupying a lot of space where components are mounted, but also increasing a product cost. Caused.

본 고안은 상기한 종래 기술의 문제점을 감안하여 이루어진 것으로서, 정전압 다이오드와 실리콘 제어 정류 소자(SCR)의 결합에 의한 간단한 회로 구성으로서 회로동작의 안정화를 도모함은 물론 고가인 방열판 사용을 배제함으로써 작업성을 용이하게 하고 이에 수반하여 제품 코스트의 절감을 그 목적으로 하는 것이다.The present invention is made in view of the above-described problems of the prior art, and is a simple circuit configuration by combining a constant voltage diode and a silicon controlled rectifier (SCR), which not only stabilizes circuit operation but also eliminates the use of expensive heat sinks. It is aimed at facilitating the cost and reducing the cost of the product.

이러한 목적을 달성하기 위한 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention for achieving this purpose is described in detail by the accompanying drawings as follows.

제1도는 본 고안에 의한 정전압 안정화 회로 구성도를 나타낸 것으로서, 교류 전원 입력단(AC)에 직렬접속된 저항(R1) 및 콘덴서(C1)를 통해 브리지 정류회로(BD)의 정(+) 전원 출력단에는 실리콘 제어 정류 소자(SCR)의 애노드측과 저항(R2)을 통하여는 정전압 다이오드(ZD)의 캐소드측을 연결하고, 상기 실리콘 제어 정류 소자(SCR)의 게이트측은 정전압 다이오드(ZD)의 애노드측에 연결하며, 또한, 상기 브리지 정류회로(BD)의 정(+) 전원 출력단에 다이오드(D1) 및 콘덴서(C2)를 연결하여 구성된 것이다.1 is a block diagram of a constant voltage stabilization circuit according to the present invention, and the positive (+) power output terminal of the bridge rectifier circuit BD through a resistor R1 and a capacitor C1 connected in series with the AC power input terminal AC. An anode side of the silicon controlled rectifying element SCR and a cathode side of the constant voltage diode ZD are connected through a resistor R2, and a gate side of the silicon controlled rectifying element SCR is an anode side of the constant voltage diode ZD. And a diode (D1) and a capacitor (C2) connected to the positive power output terminal of the bridge rectifier circuit (BD).

미설명 부호 Vcc는 안정된 직류전압이다.Reference numeral Vcc is a stable DC voltage.

이와 같이 구성된 본 고안의 동작 및 작용효과를 제2도 및 제3도를 참조하여 설명하면 다음과 같다.The operation and the effect of the present invention configured as described above will be described with reference to FIGS. 2 and 3.

제1도에서 소정의 교류전압(AC)이 전류제한용 저항(R1) 및 콘덴서(C1)를 거쳐 브리지 정류회로(BD)의 입력단에 가해지면 그의 출력단에는 제2도의 (a)에서와 같이 브리지 정류된 신호파형(BD)이 나타나게 된다.In FIG. 1, when a predetermined AC voltage AC is applied to the input terminal of the bridge rectifying circuit BD through the current limiting resistor R1 and the capacitor C1, the output terminal thereof has a bridge as shown in (a) of FIG. The rectified signal waveform BD is shown.

이와 같은 전압은 저항(R2)을 거쳐 정전압 다이오드(ZD)에 가해지게 되는데, 이때 정전압 다이오드(ZD)의 설정전압(Zv) 및 설정전류(Zi)가 인가되기 이전까지는 정전압 다이오드(ZD)는 턴 오프 상태가 되어 실리콘 제어 정류 소자(SCR)의 게이트측에 트리거 신호가 가해지지 않으므로 이로 인해 실리콘 제어 정류 소자(SCR)도 턴 오프 상태를 유지하게 된다.Such a voltage is applied to the constant voltage diode ZD through the resistor R2, and the constant voltage diode ZD is turned until the set voltage Zv and the set current Zi of the constant voltage diode ZD are applied. Since the trigger signal is not applied to the gate side of the silicon control rectifier SCR, the silicon control rectifier SCR also maintains a turn off state.

이와 같이 실리콘 제어 정류 소자(SCR)가 턴 오프된 상태에서 브리지 정류회로(BD)의 출력단 전압이 정전압 다이오드(ZD)의 설정전압치(Zv) 및 설정전류치(Zi) 이상이 되면 실리콘 제어 정류 소자(SCR)가 턴온되므로 그의 양단 전위치가 OV 상태가 된다.As described above, when the output terminal voltage of the bridge rectifying circuit BD is equal to or higher than the set voltage value Zv and the set current value Zi of the constant voltage diode ZD while the silicon control rectifier SCR is turned off. Since (SCR) is turned on, all positions at both ends thereof become the OV state.

이때 실제로 발생되는 열은 브리지 정류회로(BD)의 출력단 전압이 정전압 다이오드(ZD)의 설정 전압(Zv) 레벨에 도달되기 전까지만 미세하게 발생되므로 별도로 방열판을 설치할 필요가 없는 것이다.At this time, since the heat generated is generated only finely until the output terminal voltage of the bridge rectifying circuit BD reaches the set voltage Zv level of the constant voltage diode ZD, there is no need to install a heat sink separately.

한편 도시 생략된 부하측에는 콘덴서(C2)에 충전되어 있던 전압이 가해져 부하를 동작시키게 된다.On the other hand, the voltage charged in the capacitor C2 is applied to the load side (not shown) to operate the load.

제3도는 제1도의 등가회로 구성도를 나타낸 것이다.3 shows an equivalent circuit diagram of FIG.

이상에서와 같이 본 고안은 리모콘 등(Lamp), 리모콘 커텐, 인체 감지기, 오존 발생기 등 저용량 부하단의 정전압 회로에서 발생되는 열을 최대한 억제하여 부하시 정전압 출력단에서 발생하는 열을 방출코자 별도로 방열판을 설치하던 종래 기술의 문제점을 해소함으로써 부품이 장착되는 공간 점유율을 대폭 감소시킴은 물론 제품 코스트를 절감할 수 있는 실용적인 고안인 것이다.As described above, the present invention suppresses heat generated from the constant voltage circuit of the low-capacity load stage, such as a remote control lamp, a remote control curtain, a human body detector, and an ozone generator as much as possible to release heat generated from the constant voltage output stage under load. By eliminating the problems of the prior art that is installed, it is a practical design that can significantly reduce the space occupancy in which the components are mounted, as well as reduce the product cost.
