본 고안은 무 정전 전원 장치에 관한 것으로, 특히 SMPS(Switching Mode Po wer Supply)를 사용하는 모든 전자 제품에 적용되어 정전시에 전원을 공급하는 무정전 전원 장치에 관한 것이다.The present invention relates to an uninterruptible power supply, and more particularly, to an uninterruptible power supply that is applied to all electronic products using a switching mode power supply (SMPS) to supply power during a power failure.
제 1도에 나타난바와 같이 종래의 무 정전 전원 장치는 모드 전환 스위치(4)가 AC 전원단에 직접 연결되어 AC 입력을 SMPC(100)에 공급한다.As shown in FIG. 1, the conventional uninterruptible power supply has a mode changeover switch 4 directly connected to an AC power supply to supply an AC input to the SMPC 100.
평상시 정류기(1)는 AC 입력을 DC로 정류하여 축전지(2)에 충전하고 있다가, 정전이 되면 상기 모드 전환 스위치(4)는 전력 변환기(3)로 연결되고 상기 전력 변환기(3)는 상기 축전지(2)에서 DC를 공급받아 AC로 변환하여 상기 SMPC(100)로 공급한다.Normally, the rectifier 1 rectifies the AC input to DC and charges the battery 2. When the power failure occurs, the mode changeover switch 4 is connected to the power converter 3, and the power converter 3 is connected to the power converter 3. DC is supplied from the storage battery 2 and converted into AC and supplied to the SMPC 100.
상기 SMPC(100)로 공급된 전류는 정류기(5)에서 다시 DC로 정류되어 전력 변환기(6)에 인가되고 상기 전력 변환기(6)에 의해 변환된후 정류기(7)에 의해 DC로 정류되어 각 소자 회로에 공급된다.The current supplied to the SMPC 100 is rectified to DC in the rectifier 5 and applied to the power converter 6, converted by the power converter 6, and then rectified to DC by the rectifier 7. Supplied to the device circuit.
그러나 종래의 무 정전 장치는 2번의 전력 변환을 거치기 때문에 전력 변환 효율이 64%로 저하되고 결국 장시간 전력을 공급하기 위해서는 축전지의 용량이 커져야 하는 문제점이 있었다.However, the conventional electrostatic device has a problem in that the power conversion efficiency is reduced to 64% because of two power conversions, and the capacity of the storage battery must be increased in order to supply power for a long time.
본 고안은 상기 목적을 달성하기 위하여 안출된 것으로서, 정전시에도 1회의 전력 변환으로 전원 공급을 가능하게 함으로서 전력 이용의 효율을 높일 수 있는 무 정전 장치를 제공함에 그 목적이 있다.The present invention has been made in order to achieve the above object, it is an object of the present invention to provide a non-electrostatic device that can increase the efficiency of power use by enabling power supply in a single power conversion even during a power failure.
본 고안은 상기 목적을 달성하기 위하여 무 정전 전원 장치에 있어서, 충전을 위한 축전지, 축전지에 연결되며 AC가 인가되는 충전 및 정전 감지수단, 상기 축전지와 충전 및 정전 감지수단에 연결된 트라이 액(triac), 상기 충전 및 정전 감지 수단과 트라이액에 연결된 SMPC(Switching Mode Power System)으로 구성된다.In order to achieve the above object, the present invention provides a battery for charging, a charge and power failure sensing means connected to a battery and applied with AC, a triac connected to the battery and the charge and power failure sensing means. And a switching mode power system (SMPC) connected to the charging and power failure sensing means and the triac.
이하 첨부된 제2도를 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIG. 2.
제 2 도는 본 고안의 일 실시예를 나타내는 상세 블록도이다.2 is a detailed block diagram showing an embodiment of the present invention.
도면에서 8은 축전지, 9는 충전 및 정전 감지기, 10은 SCR, 11과 13은 정류기, 12는 전력 변환기, 200은 SMPS를 나타낸다.In the figure, 8 is a storage battery, 9 is a charge and power failure detector, 10 is an SCR, 11 and 13 are rectifiers, 12 is a power converter, and 200 is an SMPS.
본 고안의 구성은 다음과 같다.The configuration of the present invention is as follows.
축전지(8)에 충전 및 정전 감지기(9)와 SCR(Silicon Controlled Rectifier: 10)의 에노드단을 연결하고 상기 충전 및 정전 감지기(9)와 상기 SCR(10)의 게이트단을 연결하며 상기 SCR(10)의 캐소드단에 SMPS(200)내부에 있는 전력 변환기(12)를 연결하여 구성한다.An anode end of a charge and power failure detector 9 and an SCR (Silicon Controlled Rectifier) 10 is connected to a storage battery 8, and a gate end of the charge and power failure detector 9 and the SCR 10 is connected to the SCR. A power converter 12 inside the SMPS 200 is connected to the cathode end of the configuration 10.
또한 상기 충전 및 정전 감지기(9)에 AC를 인가하고 상기 SMPS(200)의 구성은 정류기(11)에 AC를 인가하고 상기 정류기(11)와 전력 변환기(12)를 연결하며 상기 전력 변환기(12)에 정류기(13)를 연결하여 구성한다.In addition, AC is applied to the charge and power failure detector 9 and the configuration of the SMPS 200 applies AC to the rectifier 11, connects the rectifier 11 and the power converter 12, and the power converter 12. It is configured by connecting the rectifier 13 to the).
이때 상기 전력 변환기(12)는 1차 코일(N1,N2)을 병렬로 연결하여 구성하고 2차 코일(N3)은 상기 정류기(13)에 연결하며 상기 1차 코일(N1)은 상기 정류기(11)에 연결하여 구성한다.In this case, the power converter 12 is configured by connecting the primary coils N1 and N2 in parallel, the secondary coil N3 is connected to the rectifier 13, and the primary coil N1 is the rectifier 11. ) To configure.
상기한 바와 같이 구성된 본 고안의 동작은 다음과 같다.The operation of the present invention configured as described above is as follows.
정상적인 AC 입력시에는 상기 SMPS(200)내부에 있는 정류기(11)에 의해 DC로 정류되고 상기 전력 변환기(12)의 1차측 코일(N1)과 2차측 코일(N3)에 의해 전력 변환되며 상기 정류기(13)에 의해 정류된 후 각 부하에 공급된다.During normal AC input, the rectifier 11 is rectified to DC by the rectifier 11 inside the SMPS 200, and the power is converted by the primary coil N1 and the secondary coil N3 of the power converter 12. It is rectified by 13 and supplied to each load.
그런데, 정전이 되어 전원 공급이 중단되면 정상 동작시 상기 축전지(8)는 충전 및 정전 감지기(9)에 의해 충전되어 있다가 정전시가 되면 충전 및 정전 감지기(9)에 의해 상기 SCR(10)의 이트단으로 전류를 흘려주어 턴 온(turn on)되어 상기 축전지(8)의 전력이 상기 SCR(10)을 통해 상기 전력 변환기(12)에 공급됨으로써, 상기 전력 변환기(12)의 1차측 코일(N2)과 2차측 코일(N3)에 의해 전력 변환이 이루어져 상기 정류기(13)에 의해 정류되어 각 부하로 공급된다.However, when the power supply is stopped due to a power failure, the storage battery 8 is charged by the charging and power failure detector 9 during normal operation, and when the power failure occurs, the SCR 10 is charged by the charging and power failure detector 9. A current is supplied to the power stage of the power converter 12 by supplying current to the power stage of the power supply 12 by supplying power to the power converter 12 through the SCR 10. Power conversion is performed by N2 and the secondary coil N3, rectified by the rectifier 13, and supplied to each load.
상기한 바와 같이 본 고안은 단지 1회의 전력 변환으로 전력 이용의 효율을 극대화 하는 장점이 있었다.As described above, the present invention had the advantage of maximizing the efficiency of power use by only one power conversion.
