그러나 이런 종래의 전원회로는, 교류(AC)전원을 브릿지정류부(BD)에서 반파정류하여 피-더블류-엠IC(PWM)의 B+단자로 공급하였으나, 콘덴서(C1)의 용량값이크며 그의 용량값에 따라 내압이 높은 스위칭트랜지스터(TR)를 사용하므로써 코스트가 상승하는등 문제점이 발생되었던 것이다.However, in the conventional power supply circuit, AC power is half-wave rectified by the bridge rectifying part BD to be supplied to the B + terminal of the P-double-emIC (PWM), but the capacitance value of the capacitor C 1 The problem arises, such as a cost increase, by using a switching transistor TR having a large and high breakdown voltage according to its capacitance value.

본고안은 상기와 같은 종래의 문제점을 해결하고자 이루어진 것으로서, 그 목적은 트랜지스터의 동작원리를 이용하여 피-더블류-엠IC(PWM)를 에이-시(AC)100V에서 220V까지 기동시킬 수 있도록한 목적과, 또다른 목적은 저항과 제너다이오드의 정수에 의하 피-더블류-엠IC를 에이-시(AC)100V 온리(Only)에서 220V 온리로 기동시킬 수 있도록 하는데 그 목적이 있다.The purpose of the present invention is to solve the conventional problems as described above, and its purpose is to enable the P-Double-MIC (PWM) to start from 100V to 220V by using the operation principle of the transistor. One purpose and another aim is to enable the P-Double-MIC to be started from AC 100V only to 220V only by the resistor and the zener diode constant.

상기 목적한 바에 의하여 내압이 높은 스위칭 트랜지스터를 사용하지 않고서도 트랜지스터의 동작원리를 이용하여 피-더블류-엠IC를 기동시켜주므로써 코스트를 절감시킬 수 있게한 것이다.For this purpose, it is possible to reduce the cost by activating the P-Double-MIC using the operation principle of the transistor without using a switching transistor having a high breakdown voltage.

상기의 목적을 달성하고자 본고안은 트랜지스터의 동작원리를 이용하여 피-더블류-엠IC를 에이-시 100V에서 200V까지 기동시킬 수 있도록 제1전원회로부를 구성한 것과, 또한 저항과 제너다이오드의 정수에 의해 피-더블류-엠IC를 에이-시 100V 온리에서 220V 온리로 기동시킬 수 있도록 하는 제2전원기동회로부를 구성한 것이 그 특징이 있다.In order to achieve the above object, the present proposal is to configure the first power supply circuit part to start the P-Double-MIC from 100V to 200V in accordance with the operation principle of the transistor, and also the constant of the resistor and the zener diode.

제2도는 본고안의 전원기동회로도로서, 다음과 같이 구성되어 있다.2 is a power supply start circuit diagram of the present invention, and is configured as follows.

교류(AC)전원을 반파정류하는 브릿지정류부(BD)에 트랜스(T1)2차측의 코일단자(1)와, 그리고 콘덴서(C1)와 저항(R1)및 다이오드(D1)를 통해 피-더블류-엠IC(PWM)의 B+단자를 각각 연결하고, 트랜지스터(TR)의 에미터측이 접지된 그의 콜렉터측은 트랜스(T1)2차측의 코일단자(2)에, 트랜스(T1)2차측의 코일단자(3)는 다이오드(D2)를 통해 피-더블류-엠IC(PWM)의 B+단자에 각각 연결 구성한 것에 있어서,The bridge rectifier BD for half-wave rectifying AC power through the coil terminal 1 of the transformer (T 1 ) secondary side, and the capacitor (C 1 ), the resistor (R 1 ), and the diode (D 1 ). The collector side of the B + terminal of the P-double-emIC (PWM) is connected to each other and the emitter side of the transistor TR is grounded to the coil terminal 2 of the transformer (T 1 ) secondary side and the transformer (T). 1 ) The secondary coil terminal 3 is connected to the B + terminal of the P-Double-MIC (PWM) through the diode D 2 , respectively.

상기 접속점(A)과, 피-더블류-엠IC(PWM)의 B+및 VCC단자사이에 트랜지스터의 동작원리에 의하여 피-더블류-엠IC를 에이-시100V에서 220V까지 기동시킬 수 있도록 제1전원기동회로부(10)를 연결하여서 구성한 것이다.Between the connection point A and the B + and VCC terminals of the P-MIC (PWM), the P-D-IC can be started from 100 V to 220 V according to the operation principle of the transistor. 1 is configured by connecting the power supply start circuit unit (10).

상기 제1전원기동회로부(10)는 트랜지스터(TR1),(TR2)와 저항(R2),(R3)및 다이오드(D3)로 구성된다.The first power source start-up circuit unit 10 includes transistors TR 1 , TR 2 , resistors R 2 , R 3 , and diode D 3 .

이와같이 구성된 본고안의 작용효과를 설명하면 다음과 같다.The operational effects of the proposed paper thus constructed are as follows.

먼저 에이-시입력단자(AC)로 교류(AC)전원이 입력되면, 입력된 교류(AC)전원은 브릿지정류부(BD)에 의해 반파정류되고, 반파정류된 전압이 제1전원기동회로부(10)로 인가되어 저항(R2),(R3)에 의해 각각 분배된다.First, when AC power is input to the AC input terminal AC, the input AC power is half-wave rectified by the bridge rectifier BD, and the half-wave rectified voltage is first-power-operated circuit unit 10. Are distributed by resistors R 2 and R 3 , respectively.

그럼 트랜지스터(TR1)는 저항(R2)에 의해 분배된 전압과, 저항(R3)에 의해 분배된 전압에 의해 턴온 되어 반파정류된 전압은 턴온된 트랜지스터(TR1)의 콜렉터와 에미터측및 다이오드(D3)를 통해 피-더블류-엠IC(PWM)의 VCC단자에 인가된다.Then transistor (TR 1) is teocheuk the collector and emitter of the resistor (R 2) the voltage and the resistance (R 3) a transistor (TR1) half-wave rectified voltage is turned on by the divided voltage is turned on by the distributed by and It is applied to the VCC terminal of the P-double-emIC (PWM) through the diode D 3 .

이와동시에 트랜스(T1)의 2차측에 유기된 전압이 다이오드(D2)를 통해 트랜지스터(TR2)의 베이스측으로 가해지므로서 트랜지스터(TR3)가 턴온되고, 따라서 트랜지스터(TR2)가 턴온 됨에따라 반파정류된 전압은 저항(R3)과 트랜지스터(TR2)의 콜렉터와 에미터측을 통해 바이패스되고, 따라서 트랜지스터(TR1)는 턴오프 상태가 되어 피-더블류-엠IC(PWM)에는 B+전압이 계속인가 되어 피-더블류-엠IC는 계속 동작한다.At the same time, the transistor TR 3 is turned on as the voltage induced on the secondary side of the transformer T 1 is applied to the base side of the transistor TR 2 through the diode D 2 , and thus the transistor TR 2 is turned on. As a result, the half-wave rectified voltage is bypassed through the collector and emitter sides of the resistor R 3 and transistor TR 2 , so that the transistor TR 1 is turned off and thus the P-double-MIC PWM ), B + voltage is applied continuously so that the P-Double-MIC continues to operate.

이렇게 피-더블류-엠IC를 에이-시(AC)100V에서 220V까지 기동시킬 수 있게한 것이다.Thus, the P-Double-MIC can be started from 100V to 220V.

한편 제3도는 제2전원기동회로부(20)를 구성한 다른 일실시예의 회로도로서, 제1전원기동회로부(10)에서 설명한 바와마찬가지로 제3도는 저항(R4),(R5)과, 제너다이오드(ZD)의 정수에 의해 피-더블류-엠IC를 에이-시(AC)100V온리(Oniy)에서 220V온리로 기동시킬 수 있게한 것이다.FIG. 3 is a circuit diagram of another embodiment of the second power source start circuit unit 20. As shown in the first power source start circuit unit 10, FIG. 3 shows resistors R 4 and R 5 and zener diodes. The integer of (ZD) allows the P-Double-MIC to be started from 100V only on AC to 220V only.

이상과같이 본고안은 제1전원기동회로부내의 트랜지스터의 동작원리를 이용하여 피-더블류-엠IC를 에이-시100V에서 220V까지 기동시킬 수 있게하고, 또한 제2전원기동회로부내의 저항과 제너다이오드의 정수에 의해 피-더블류-엠IC를 에이-시100V온리와, 220V온리로 각각 기동시킴으로써 코스트를 절감시킬 수 있는 잇점이 있다.As described above, this proposal makes it possible to start the P-Double-MIC from 100V to 220V by using the operation principle of the transistor in the first power source start-up circuit section, and also the resistance and zener in the second power source start-up circuit section. Costs can be reduced by starting the P-Double-MIC at 100V only and 220V only by the diode constant.
