본 고안은 컴퓨터의 전원공급회로에 관한 것으로 특허 주변기기로 공급되는 공급전원에 시차를 두어 주변기기의 전원이 안정하게 공급되도록 한 전원공급안정화 회로에 관한 것이다.The present invention relates to a power supply circuit of a computer, and relates to a power supply stabilization circuit for stably supplying power of a peripheral device by staggering the supply power supplied to a patent peripheral device.
종래의 기술은 중앙처리장치(CPU)와 주변기기를 사용하는 컴퓨터 시스템에 있어, 콘트롤 패널의 스위치나 키이에 의해서 전원을 공급할 경우 전원이 중앙처리장치나 주변기기로 동시에 안가되도록 과부하 걸려 기타 다른기기에 악영향을 주는 문제점이 있었다.The prior art is a computer system using a central processing unit (CPU) and a peripheral device. When the power is supplied by a switch or a key of a control panel, the power is overloaded so that the power is not simultaneously transmitted to the central processing unit or the peripheral device. There was a problem.
이에 본 고안은 상기한 문제점을 개설시키기 위해 안출된 것으로서, 간단한 타이머 IC를 사용하여 전원의 공급에 시간차이를 두어 주변기기의 전원공급을 안정화시키도록 한 것으로, 이하 그의 기술구성을 첨부된 도면에 따라 설명하면 다음과 같다.Accordingly, the present invention has been made to solve the above problems, and by using a simple timer IC to stabilize the power supply of the peripheral device by giving a time difference to the power supply, the technical configuration of the following according to the accompanying drawings The explanation is as follows.
제1도는 본 고안에 따른 전원공급 안정화 회로를 나타낸 것으로 그의 연결구성을 살펴보면, 서킷 브레이커(1)가 전원분배장치(2)와 연결되어 라인필터(3)를 거쳐 레귤레이터(4)에 접속되고, 전원분배장치(2)는 전원스위치(SW1)와 연결되며 DC레귤레이터(5)를 거쳐 스위치(SW2)의 단자(NC)(NO)에 접속되고, 상기 DC레귤레이터(4)외 출력단은 타이머 IC(6)에 접속되며 동시에 릴레이(7)에 접속되고, 타이머 IC(6)외 콜렉터(C)는 스위치(SW2)에 연결되며 동시에 다이오우드(D1)를 거쳐 트리거단자(T)에 접속되고, 타이머 IC(6)는 저항(R1)과 콘덴서(C1)의 시정수와 연결되며 타이머IC(6)의 에미터(E)는 접지접속되는 구성으로 상기 타이머IC(6)의 시정수 상세회로는 제2도에 나타내었다.1 shows a power supply stabilization circuit according to the present invention. Looking at the connection configuration thereof, a circuit breaker 1 is connected to a power distribution device 2 and connected to a regulator 4 via a line filter 3, The power distribution device 2 is connected to the power switch SW 1 and connected to the terminal NC of the switch SW 2 via the DC regulator 5, and the output terminal other than the DC regulator 4 is a timer. Connected to the IC 6 and simultaneously to the relay 7, the collector IC other than the timer IC 6 is connected to the switch SW 2 and simultaneously connected to the trigger terminal T via the diode D 1 . The timer IC 6 is connected to the time constant of the resistor R 1 and the condenser C 1 , and the emitter E of the timer IC 6 is connected to the ground to correct the timer IC 6. The detailed circuit is shown in FIG.
상기 회로구성의 동작상태 및 작용효과를 첨부된 도면에 따라 설명하면 다음과 같다.The operation state and effect of the circuit configuration will be described with reference to the accompanying drawings.
제1도에서 서킷브레이커(1)를 온시키고 전원스위치(SW1)을 온시키면 전원분배장치(2)에 AC전원이 공급되고, 전원콘트롤 조직에도 AC전원이 공급된다.In FIG. 1, when the circuit breaker 1 is turned on and the power switch SW 1 is turned on, AC power is supplied to the power distribution device 2, and AC power is also supplied to the power control structure.
상기 전원분배장치(2)외 출력AC전원은 DC레귤레이터(4)에 의해 DC12(V)가 생성되어 스위치(SW2)에 인가되는데, 스위치(SW2)는 노말크로즈(NC)상태로 되어 있으므로 다이오우드(D1)를 거쳐 타이머IC(6)의 트리거 단자(T)에 인가된다.The power distribution unit (2) Other than the output AC voltage, there is applied to the DC12 (V) is generated and the switch (SW 2) by the DC regulator (4), since the switch (SW 2) is in sucrose n (NC) state It is applied to the trigger terminal T of the timer IC 6 via the diode D 1 .
상기 타이머 IC(6)는 저항(R1)과 콘덴서(C1)의 시정수에 의해 이 시정수시간이 경과한 후에 동작되므로 타이머 IC(6)의 콜렉터(C)와 에미터(E)가 연결되어, 즉 릴레이(7)외 플러스 단자(+)가 접지상태로 되어 마이너스단자(-)에 DC12(V)가 공급되고, 플러그단자(+)는 접지상태가 되어 릴레이(7)의 코일이 자화되어 1과 2가 연결된다.Since the timer IC 6 is operated after the time constant time has elapsed by the time constants of the resistor R 1 and the capacitor C 1 , the collector C and the emitter E of the timer IC 6 are operated. That is, the positive terminal (+) other than the relay (7) is grounded, so that DC12 (V) is supplied to the negative terminal (-), and the plug terminal (+) is grounded, so that the coil of the relay (7) Magnetized to connect 1 and 2.
그러므로 출력단으로는 릴레이(7)의 구동에 따라 일정시간이 지난후 안정된 전압이 출력되게 된다.Therefore, a stable voltage is output to the output terminal after a predetermined time due to the driving of the relay 7.
따라서 본 고안에 따른 컴퓨터의 전원공급안정화회로는 이상의 설명에서와 같이, 콘트롤 패널의 스위치나 키이에 의하여 동시에 전원을 공급할 경우 타이머 IC에 의해서 타임 지연기능을 주어 동시에 과부하가 걸려 기타라는 기기에 영향을 주는 것을 방지시키며, 컴퓨터의 중앙처리 장침 및 주변기기의 통합적인 전원조절을 할 수 있을 뿐 아니라 전원에서 발생되는 과전류 및 과부하에 의한 충격을 방지시켜 전원을 안정화시키는 효과를 갖게 된다.Therefore, the power supply stabilization circuit of the computer according to the present invention has a time delay function by the timer IC when the power is simultaneously supplied by a switch or a key of the control panel, which causes an overload to affect other devices. In addition to the integrated power control of the computer's central processing hand and peripherals, it also has the effect of stabilizing the power supply by preventing the shock caused by over current and overload generated from the power supply.
