본 고안은 부전위 시스템(Negative power System)에서 상전감시 장치에 관한 것으로, 특히 밧데리를 충전하거나 또는 빠른 상전감지를 요구하는 채터링(Chattering)이 제거된 감지회로를 요구하는 회로에 적합하도록 한 부극성 상전감시 및 밧데리 충방전회로에 관한 것이다.The present invention relates to a phase change monitoring device in a negative power system, and is particularly suitable for a circuit requiring a sensing circuit without charging a battery or a chattering without the need for fast phase detection. The present invention relates to a polarity phase monitoring and a battery charge / discharge circuit.

종래의 밧데리 충방전회로나 상전감지 회로는 접점이 온·오프될 때 정상적인 폐로 상태로 되기전에 여러번 미세한 피폐운동을 반복하는 경우가 발생(채터링현상)하여 접점의 수명을 단축시키게 되는 문제점이 있었다.Conventional battery charge / discharge circuits or phase change detection circuits have a problem in that, when the contacts are turned on or off, there are cases in which fine closed movements are repeated several times before they become normally closed (chatting), thereby shortening the life of the contacts. .

따라서 본 고안의 목적은 상기와 같은 종래기술의 문제점을 감안하여 밧데리 충전과 상전감지를 하여 채터링이 발생하지 않도록 함에 있는 것이다.Therefore, the object of the present invention is to prevent the chattering by the battery charging and phase change in view of the problems of the prior art as described above.

이러한 목적을 달성하기 위한 본 고안은 브리지 정류회로의 출력을 분압 및 평활시키는 분압 및 평활회로와, 상기 분압 및 평활회로를 통한 전압레벨과 정전압부에 의해 설정되는 기준 전압레벨을 비교하여 로우 또는 하이 논리신호를 출력하는 비교회로와, 상기 비교회로의 출력상태에 따라 릴레이의 구동을 온, 오프 제어하여 상기 릴레이의 접점을 온, 오프시켜 충전루프를 형성하는 스위칭회로를 구비하여서 된 것을 특징으로 한다.The present invention for achieving this purpose is to compare the voltage dividing and smoothing circuit for dividing and smoothing the output of the bridge rectifier circuit, and the voltage level through the voltage dividing and smoothing circuit and the reference voltage level set by the constant voltage section, low or high And a switching circuit for outputting a logic signal and a switching circuit for controlling the driving of the relay according to the output state of the comparing circuit to turn on and off the contact of the relay to form a charging loop. .

이하 본 고안을 첨부된 도면에 따라 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도와 같이 AC 전원 단자에 접속된 트랜지(T)를 거쳐 다이오드(D1, D2), (D3-D6)을 접속시킨 정류용 브리지회로(BD)를 구성하고, 콘덴서(C2, C3)로서 필터회로를 구성시키고, 상기 다이오드(D1, D2)사이의 단자점에서 저항(R1), (R2)을 거쳐 비교기(BP)의 반전단자(-)에 입력전압(Vin)을 인가시키도록 구성된다.As shown in FIG. 1 , a rectifier bridge circuit BD is connected in which diodes D 1 , D 2 and D 3 -D 6 are connected via a transistor T connected to an AC power supply terminal. 2 , C 3 ) and the filter circuit is configured and input to the inverting terminal (-) of the comparator BP through resistors R 1 and R 2 at the terminal points between the diodes D 1 and D 2 . It is configured to apply the voltage Vin.

또한 저항(R3, R4, R5)과 제너다이오드(ZD1), (ZD2)로서 비교기(OP)의 기준전압(Vr)이 비반전단자(+)에 설정되게 구성한 기준전압 및 비교회로와, 이 비교기(OP)의 출력을 트랜지스터(TR1)의 바이어스 저항(R6-R9)에 연결시키고 이 트랜지스터(TR1)의 콜렉터에 릴레이(RY)를 연결한 릴레이 제어회로와, 상기 트랜지스터(TR1)의 에미터단자에 저항(R10)과 다이오드(D7)를 통해 상기 릴레이(RY)의 제1접점(Y1A)이 연결되고, 상기 제1접점(Y1A)을 통해 콘덴서(C2, C3)와 접속되며, 상기 릴레이(RY)의 제2접점(Y1B)은 기저전위에 접속되므로서 충방전루프가 구성된다.In addition, the reference voltage and the comparison of the resistors (R 3 , R 4 , R 5 ) and the zener diodes (ZD 1 ) and (ZD 2 ) are configured such that the reference voltage (Vr) of the comparator (OP) is set at the non-inverting terminal (+) and a circuit, connected to the output of the comparator (OP) to a bias resistor (R 6 -R 9) of the transistor (TR 1) and connecting the relay (RY) to the collector of the transistor (TR 1) the relay control circuit, said transistor (TR 1) emitter and the first contact point (Y 1A) of the relay (RY) connected to a terminal through a resistance (R 10) and a diode (D 7), the first contact point (Y 1A) the The capacitors C 2 and C 3 are connected to each other, and the second contact point Y 1B of the relay RY is connected to the ground potential to form a charge / discharge loop.

미설명부호 B는 밧데리 전원이고, a-f는 각 단자점을 나타낸 것이다.Reference numeral B denotes a battery power source and a-f denotes each terminal point.

이와같이 구성된 본 고안의 동작을 제2도를 참조하여 설명하면 다음과 같다.Referring to Figure 2 the operation of the present invention configured as described above is as follows.

먼저, 상전이 정상이고 밧데리 전압이 정상 상태 일때에는 제2a도와 같이 기준전압(Vr)이 입력전압(Vin)보다 낮은 전위(비교기의 접지점에서 보면 반대로 기준전위가 높음)가 되므로서 비교기(OP)의 출력은 단자점(e)의 전위와 근사치로 출력된다.First, when the phase change is normal and the battery voltage is normal, the reference voltage Vr becomes a potential lower than the input voltage Vin (as opposed to the ground point of the comparator) as shown in FIG. The output is output close to the potential of the terminal point e.

그리고 출력전위는 트랜지스터(TR1)를 도통시켜 릴레이(RY)을 여자시키고 이 릴레이의 접점(Y1A)이 온되어 저항(R10)과 다이오드(D7) 및 접점(Y1A)을 통해 충전 및 밧데리의 B+ 전원루프(Loop)로 밧데리 충전루프가 형성된다. 한편, 제1접점(Y1B)는 오프되어서 부하는 밧데리가 아닌 전원회로에 의해 정상동작을 하게 된다.The output potential conducts the transistor TR 1 to excite the relay RY, and the contact Y 1A of the relay is turned on to charge through the resistor R 10 , the diode D 7 , and the contact Y 1A . And a battery charging loop is formed by the B + power loop of the battery. On the other hand, the first contact Y 1B is turned off so that the load operates normally by the power supply circuit rather than the battery.

한편 상전 폐했을때(비정상상태 fail)에는 제2b도와 같이 입력전압(Vin)의 맥류값은 접지점으로 전위가 올라가는데, 그 속도는 상전이 폐(fail)되는 속도에 따른 저항(R2)과 콘덴서(C1)의 시정수(R2×C1)의 값으로 거의 결정되므로서 그 시간은 콘덴서(C1) 및 저항(R2)으로서 설정하여 빠르게 할 수가 있다.On the other hand, when the phase is closed (abnormal state fail), as shown in FIG. 2b, the pulse voltage value of the input voltage Vin rises to the ground point, and the speed is the resistance (R 2 ) and the capacitor according to the speed at which the phase transition fails. Since it is almost determined by the value of the time constant (R 2 × C 1 ) of (C 1 ), the time can be set faster as the capacitor C 1 and the resistor R 2 .

입력전압(Vin)이 기준전압(Vr)에 도달하면 기준전압(Vr)이 입력전압(Vin) 보다 높은 전위 [비교기(OP)의 접지점에서 보면 반대로 기준전압(Vr)이 낮음]로 비교기(OP)의 출력은 밧데리(B+)값 근처로 출력되어 트랜지스터(TR1)를 오프시켜 릴레이(RY)를 오프시키므로서 접점(Y1A)이 오프되어 충전루프가 차단되고, 상기 릴레이접점(Y1B)이 온되어 부하에 밧데리를 연결 정상 동작을 하게 된다.When the input voltage Vin reaches the reference voltage Vr, the reference voltage Vr is higher than the input voltage Vin (the reference voltage Vr is low in contrast to the ground point of the comparator OP). ) Outputs near the battery (B + ) value, turns off the transistor (TR 1 ), turns off the relay (RY), turns off the contact (Y 1A ), cuts off the charging loop, and the relay contact (Y 1B). ) Will turn on and connect the battery to the load for normal operation.

또한 저항(R6)을 통해 히스테리시스 특성을 부여하므로 단자점(a)의 기준전압(Vr)은 기준전압레벨(Vrl)로 하강되어 기준전압(Vr) 근처의 입력전압(Vin)값에 의한 채터링이 제거된다.In addition, since the hysteresis characteristic is given through the resistor R 6 , the reference voltage Vr of the terminal point a is lowered to the reference voltage level Vrl, and the chatter is generated by the input voltage Vin near the reference voltage Vr. The ring is removed.

다시 AC 전원이 온 되어도 그 반대로 기준전압레벨(Vrl)이 기준전압(Vr)으로 이동되므로 역시 채터링이 발생되지 않는다.When the AC power is turned on again, on the contrary, since the reference voltage level Vrl is moved to the reference voltage Vr, chattering does not occur.

즉, AC 전원이 온되면 입력전압(Vin)이 맥류값인 기준전압(Vrl)값에 도달되면 비교기(OP)의 출력은 단자점(e)의 전위를 출력하여 트랜지스터(TR1)를 토통시켜 릴레이(RY)를 여자시키므로 접점(Y1)이 온되어 충전루프를 형성하며 이같은 비교기(OP)의 비반전 입력단자점(a)에 가해지던 기준전압레벨(Vrl)에서 기준전압(Vr)으로 상승시키는 히스테리시스 작용을 하므로 기준전압레벨(Vrl)근처에서의 입력전압(Vin) 맥류값은 히스테리시스 값보다 작을때 채터링현상을 발생시키지 않게 된다.That is, when the AC power is turned on, when the input voltage Vin reaches the reference voltage Vrl value, which is a pulse current value, the output of the comparator OP outputs the potential of the terminal point e and causes the transistor TR 1 to pass through. Since the relay RY is excited, the contact Y 1 is turned on to form a charging loop, and from the reference voltage level Vrl applied to the non-inverting input terminal point a of the comparator OP to the reference voltage Vr. Since the hysteresis action increases, the input voltage Vin near the reference voltage level Vrl does not cause chattering when the pulse voltage is smaller than the hysteresis value.

그리고 상전감지의 출력은 비교기(OP)의 출력단자(C)에 나타나는 신호값에 의해 얻을 수 있게 된다.The output of the phase change detection can be obtained by the signal value displayed on the output terminal C of the comparator OP.

이상에서 설명한 바와같이 본 고안은 부전위 시스템에서 AC를 감지하는데 빠르고 채터링을 제거하여 빠른 상전을 요하는 회로에 이용할 수 있는 것이어서, 소자의 수명을 최대한 연장시킬 수가 있다.As described above, the present invention can be used in a circuit requiring fast phase change by quickly removing chattering to detect AC in a potential dislocation system, thereby extending the life of the device as much as possible.
