본 발명은 전원회로에 관한 것으로서, 특히 어댑터 조정회로에 관한 것이다.The present invention relates to a power supply circuit, and more particularly to an adapter adjustment circuit.

종래에는, 콘센트로부터 들어온 전원을 트랜스를 사용하여 전압을 전환하는데 있어서, 온-오프제어시에 전자접촉기나 전력용스위치가 이용되었지만 접점의 마모소를 발생이라는 결점이 있었다.Conventionally, in switching power from a power outlet using a transformer, a magnetic contactor or a power switch is used during on-off control, but there is a drawback that wear of a contact occurs.

따라서, 최근에는 트랜스를 사용하지 않는 전압변환회로가 많이 생산되었다.Therefore, in recent years, many voltage conversion circuits that do not use transformers have been produced.

이러한 전압변환회로에는 종래의 스위치 대신에 사이리스터(Thyrister)나 트라이악(Triac)을 이용하여 외부 전원을 변압하게 되었다.In such a voltage conversion circuit, a thyristor or triac is used instead of a conventional switch to transform an external power source.

이에 따라, 상기 외부전원을 변압하기 위하여 어댑터(adapter)가 필요하게 되었다.Accordingly, an adapter is required to transform the external power source.

따라서, 본 발명에서는 전원회로에 있어서 전원을 조정하기 위한 어댑터 조정회로를 제공하는데 목적이 있다.Accordingly, an object of the present invention is to provide an adapter adjusting circuit for adjusting a power supply in a power supply circuit.

상기 목적을 달성하기 위하여 본 발명은 첨부된 도면에 의거하여 그 구성 및 동작을 상세히 설명한다.In order to achieve the above object, the present invention will be described in detail with reference to the accompanying drawings in the configuration and operation.

제1도는 본 발명의 회로도를 나타낸 것이다.1 shows a circuit diagram of the present invention.

이 회로도를 크게 두 부분으로 구분하면 어댑터(30)와 전원 조정부(80)로 나눈다.If this circuit diagram is largely divided into two parts, it is divided into the adapter 30 and the power adjustment part 80. FIG.

먼저, 어댑터(30)는 다음과 같은 구성 및 동작을 한다.First, the adapter 30 has the following configuration and operation.

외부의 교류전원(220V)에 접속되어 플러그(plug, 3-터미널, 교류전력용)(PLI)를 통하여 전원이 인가된다.It is connected to an external AC power supply 220V and a power supply is applied through a plug (3-terminal, AC power supply) PLI.

이때, 상기 인가된 교류전원으로 부터의 급격한 전류가 인가되는 것을 완화하기 위해서 캐패시터 0.1μF(C2) 및 저항 100Ω(R1)으로 구성된 업소버(absorber)(10)가 고전력용 스위치인 트라이악 또는 같은 전력제어 소자 역할(즉, 위상제어)을 하는 SCR(silicon-controlled rectifier) 또는 사이리스터에 병렬로 연결된다.At this time, in order to alleviate the application of the sudden current from the applied AC power source, the absorber 10 composed of a capacitor of 0.1 μF (C2) and a resistor of 100 Ω (R1) is a triac or the same power that is a high power switch. It is connected in parallel to a silicon-controlled rectifier (SCR) or thyristor that acts as a control element (ie phase control).

상기 트라이악 SCR의 차이는 SCR은 단극성으로 동작하고, 트라이악은 양극성으로 동작한다.The difference between the triac SCRs is that the SCR operates unipolar and the triac operates bipolar.

또한, 트라이악은 AC파형의 반 싸이클마다 도전되고, 또한 일련의 교류 반 싸이클의 초기 또는 끝에 전도되게 함으로써 교류전원이 부하에만 공급되게 하며, 트라이악이 도전 될 때는 전압의 극성이 반전되거나 또는 전류가 제로(zero)로 될 때까지이다.In addition, the triac is conducted every half cycle of the AC waveform and is also conducted at the beginning or end of a series of alternating half cycles so that the AC power is supplied only to the load, and when the triac is conducted, the polarity of the voltage is reversed or a current is generated. Until is zero.

또한, 상기 교류전원에 의해서 제1트라이악(TR1)을 구동하기 위하여 제1트리거펄스부(20)에서 트리거 펄스를 발생하는데, 이때, 상기 외부로부터 입력된 교류전원전압에 정이 되면 캐패시터 0.1μF(C1)는 저항 240KΩ(R2)와 가변저항(마이크로 포텐셔미터)100K(VR1)를 통해서 충전되는데, 이때 상기 캐패시터(C1)에 충전된 전압이 제1다이악(트리거 다이오드)(D1)의 브레이크 오버전압(break over)을 초과하면 제1다이악(D1)이 트리거펄스를 전원제어스위치인 제1트라이악(TR1)의 게이트(G)에 공급한다.In addition, a trigger pulse is generated by the first trigger pulse unit 20 to drive the first triac TR1 by the AC power source. At this time, when it is positive to the AC power voltage input from the outside, the capacitor is 0.1 μF ( C1) is charged through a resistor 240KΩ (R2) and a variable resistor (micro-potentiometer) 100K (VR1), wherein the voltage charged in the capacitor C1 is the breakover voltage of the first diamond (trigger diode) D1. (break over) is exceeded, the first diamond D1 supplies the trigger pulse to the gate G of the first triac TR1, which is a power control switch.

여기서, 상기 가변저항(VR1)을 조정함으로써 상기 캐패시터(C1)의 충전시간을 바꾸어 도통각(즉, 위상제어)을 변화시킬 수 있으므로서 원하는 교류전원전압(120V)을 공급한다.Here, by adjusting the variable resistor VR1, the conduction angle (ie, phase control) can be changed by changing the charging time of the capacitor C1, thereby supplying the desired AC power supply voltage 120V.

이때, 상기 공급되는 전압은 저항 1KΩ(R3)에 걸린다. 한편, 상기 제1트리거 펄스부(20)에서 공급된 펄스에 의해서 제1트라이악(TR1)의 주전극(T2,T1)을 통하여 도통되는데, 이때 상기 캐패시터(C2)는 상기 제1트라이악(TR1)이 온(ON)되면 동시에 캐패시터(C2)에 충전된 전하가 방전된다.At this time, the supplied voltage is applied to the resistor 1K? (R3). Meanwhile, the pulses supplied from the first trigger pulse unit 20 are conducted through the main electrodes T2 and T1 of the first triac TR1, wherein the capacitor C2 is connected to the first triac ( When TR1) is turned ON, the charge charged in the capacitor C2 is discharged at the same time.

다음에는, 나머지 전원조정부(80)에 대해서 설명한다.Next, the remaining power supply adjusting unit 80 will be described.

상기 어댑터(30)에 의해서 공급되는 교류전원선은 단극 스위치인 SPST 소형스위치(S1)에 연결된다.The AC power supply line supplied by the adapter 30 is connected to the SPST small switch S1 which is a single pole switch.

상기 소형스위치(S1)가 온(ON)되면 제2트리거펄스부(40)의 서로 병렬로 연결된 포텐셔미터(potential)인 가변저항(VR2,VR3)중 VR2에 세팅(setting)된 전압(위상)을 변화시킴으로써 제2트라이악(TR2)에 공급되는 트리거펄스 위상(타이밍)을 바꾸고, 부하에 공급된 평균전력레벨로 바꾸며, 캐패시터(C3)전하를 충전하는 시간을 변화시킴으로써 전원제어스위치인 제2트라이악(TR2)의 게이트(G)에 펄스를 공급한다.When the small switch S1 is turned on, a voltage (phase) set to VR2 among the variable resistors VR2 and VR3 which are potentiometers connected in parallel with each other in the second trigger pulse unit 40. By changing the trigger pulse phase (timing) supplied to the second triac TR2, changing to the average power level supplied to the load, and changing the time for charging the capacitor C3 charge, thereby changing the second tri The pulse is supplied to the gate G of the evil TR2.

이때, 제3트리거펄스부(50)의 가변저항(VR3)에 의해서 저항(R5) 및 캐패시터(C4)로 구성된 적분회로를 통하여 위상을 제어한다.At this time, the phase is controlled by the integrating circuit composed of the resistor R5 and the capacitor C4 by the variable resistor VR3 of the third trigger pulse unit 50.

캐패시터(C4)를 통과할 때 전압은 약 30V이상으로 상승한다. 상기 적분회로에 의해 제2다이악(D2)이 도통되면서, 제2트라이악(TR2)의 게이트(G)에 트리거펄스를 공급하여 턴-온(Turn-on)되게 한다.When passing through capacitor C4, the voltage rises above about 30V. As the second diaak D2 is conducted by the integrating circuit, the trigger pulse is supplied to the gate G of the second triac TR2 to be turned on.

이때, 상기 교류전원에 의해 충전된 커패시터(C6)의 방전으로 상기 제2트라이악(TR2)이 파괴되는 것을 방지하기 위해 상기 제2트라이악(TR2)과 직렬로 접속된 인덕터 50μH(L1)의 리액터를 접속하는 것으로 노이즈필터(60)가 구성된다.In this case, in order to prevent the second triac TR2 from being destroyed by the discharge of the capacitor C6 charged by the AC power supply, the inductor 50 μH (L1) connected in series with the second triac TR2 is disposed. The noise filter 60 is comprised by connecting a reactor.

또한, 상기 인덕터(L1)전류를 제어하기 위하여 수Ω의 저항을 접속하는 방법도 있다.There is also a method of connecting a resistor of several ohms to control the inductor L1 current.

상기 제2트라이악(TR2)이 턴-오프(Turn-off)될때마다 유도부하에 의해서 발생되는 전자방해로부터 보호하기 위해 저항(R6) 및 커패시터(C5)로 구성된 서지전압 방지부(70)를 제공한다.Whenever the second triac TR2 is turned off, a surge voltage prevention part 70 including a resistor R6 and a capacitor C5 is provided to protect against electromagnetic interference caused by an inductive load. to provide.

상기 제2트라이악(TR2)이 도통되면서 상기 가변저항(VR2,VR3)에 의해 출력되는 전체전원전압은 외부에 연결된 단자 잭(Jack)(SO1)에 인가되고, 이 잭(SO1)에 의해 필요한 전원을 공급할 수 있다.As the second triac TR2 is conducted, the total power supply voltage output by the variable resistors VR2 and VR3 is applied to a terminal jack SO1 connected to the outside, and is required by the jack SO1. Can supply power.

상기 잭(SO1)은 플러그(PL1)의 그라운드(접지)와 중립단자에 연결된다.The jack SO1 is connected to the ground (ground) and the neutral terminal of the plug PL1.

이와같은 구성으로 된 본 발명은 교류전압을 조정할 수 있는 가변저항(VR2,VR3) 및 전원제어스위치(TR1,TR2)에 의해서 고속으로전력을 스위칭에 의해 제어할 수 있기 때문에, 조명기구에나 전기 및 전자기기 등에 응용할 수가 있다.According to the present invention having such a configuration, since the power can be controlled at high speed by the variable resistors VR2 and VR3 and the power control switches TR1 and TR2 that can adjust the AC voltage, the lighting apparatus and the electric and It can be applied to electronic devices.
