본 고안은 절전형 무정전 전원장치에 관한 것으로, 메인 트랜스의 2차측을 정류부와 충전부로 분리시키며, 인버터의 펄스 주기를 동기시키기 위하여 인버터 일차단에 트라이악을 추가설치하고 평상시에는 SCR의 게이트 제어에 의하여 인버터를 동작 시키기 않고 정전시에만 인버터를 작동시킴으로써 절전형 무정전 전원장치를 제공할수 있도록 한 것이다.The present invention relates to a power-saving uninterruptible power supply, which separates the secondary side of the main transformer into a rectifying unit and a charging unit, and installs a triac at the primary stage of the inverter in order to synchronize the pulse period of the inverter. By operating the inverter only during power outage without operating the inverter, it is possible to provide a power-saving uninterruptible power supply.

종래의 무정전 전원장치(U. P. S)는 제 1 도에서와 같이 매칭 트랜스(MT10)의 2차측에 에스시알(SCR11)(SCR12)및 다이오드(D13)(D14)로된 정류부의 출력이 한편으로는 바테리(B)에 충전되고, 또 한편으로는 인버터(INT)의 일차측이 +를 기준으로 2분하며 상부코일, 다이오드(D15)(D16)및 에스씨알(SCR13)과 하부코일, 다이오드(D17), (D18)및 에스씨알(SCR14)의 시차분리 작동에 의한 인버터 작동을 동시에 하는 것이었다.Conventional uninterruptible power supply (UP S) is a rectifying part of the escal (SCR 11 ) (SCR 12 ) and diode (D 13 ) (D 14 ) on the secondary side of the matching transformer (MT 10 ) as shown in FIG. On the one hand, the output is charged to the battery (B), and on the other hand, the primary side of the inverter (INT) is divided into two by + and the upper coil, diode (D 15 ) (D 16 ) and SCR (SCR 13). ) And the lower coil, diodes (D 17 ), (D 18 ) and SCR (SCR 14 ) were operated at the same time by the inverter's differential separation operation.

L11, L13, L14는 코일, C11, C12, C13은 콘덴서, D11은 다이오드이다.L 11 , L 13 and L 14 are coils, C 11 , C 12 and C 13 are capacitors and D 11 is a diode.

따라서, 충전시키고자 하는 충전전압을 높이면 인버터 입력 전압 역시 높아지므로 인버터(INT)에 무부하전류 및 콘덴서(C12)의 충전전류가 증가하여 입력전류가 상당히 증대되어 매칭트랜스(MT)의 용량이 상대적으로 커지므로 제조원가의 상승은 물론 크기도 커지는 것이었다.Therefore, if the charging voltage to be charged is increased, the inverter input voltage is also increased, so that the no-load current and the charging current of the capacitor C 12 are increased in the inverter INT, and the input current is significantly increased, so that the capacity of the matching transformer MT is relatively high. As the cost increases, manufacturing cost increases as well as size.

본 고안은 위와 같은 점을 해결할 수 있도록 평상시에는 매칭 트랜스 출력을 트라이악의 수위칭 온작동에 의하여 바이패스시켜 AC전원을 사용함과 동시에 바테리에 충전을 시키고, 정전시에는 상기 트라이악의 스위칭 오프동작과 에스씨알의 온작동에 의하여 인버터가 작동케하되 인버터 트랜스의 일차단 공통 단자에 각각 트라이악을 개재시켜서 에스씨알의 오동작을 방지할 수 있도록 구성한 것으로 도면을 참조하여 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention bypasses the matching transformer output by the triac's level switching on operation, and uses the AC power to charge the battery at the same time. The inverter is operated by the ON operation of the seed, but is configured to prevent the malfunction of the SRC by interposing the triacs at the first common terminal of the inverter transformer.

매칭 트랜스(MT1)의 2차측 권선을 상, 하부로 분리하여 상부 코일 양단에 다이오드(SD1~SD4), 코일(R. S) 및 콘덴서(C1)로된 정류부와, 하부코일 양단에 다이오드(SR3)(SR44), 에스씨알(SCR1)(SCR2), 코일(C. S)및 콘덴서(C2)로 된 충전부로 분리구성하고, 충전부 출력은 바테리(B)에 접속하되-출력선은 바테리(B) 및 정류부-선과 접속하며, 상부코일 중간 탭단자를 바이패스시켜 코일 트라이악(T9)(T10)을 통하여 정현파 출력을 사용토록 하고, 콘덴서(C3)(C4), 코일(L1), 에스씨알(SCR3)(SCR4), 다이오드(SR4~SR7) 및 인버터 트랜스(IVT)로된 공지의 인버터의 인버터 트랜스(IVT) 일차권선의 +공통선이 각각 트라이악(T5)(T6)을 통하여 상, 하부 권선에 접속되도록 구성하여성 된 것이다.The secondary winding of the matching transformer MT 1 is separated into upper and lower parts, and a rectifying part including a diode SD 1 to SD 4 , a coil R. S, and a capacitor C 1 at both ends of the upper coil, and both ends of the lower coil. Separately composed of charging parts consisting of diode (SR 3 ) (SR 44 ), SCR 1 (SCR 2 ), coil (C. S) and condenser (C 2 ), and the output of the charging part is connected to the battery (B). The output line is connected to the battery (B) and the rectifier line, and bypasses the upper coil middle tap terminal to use the sine wave output through the coil triac (T 9 ) (T 10 ), and the capacitor (C 3). Inverter transformer (IVT) primary winding of a known inverter consisting of (C 4 ), coil (L 1 ), SCR 3 (SCR 4 ), diodes SR 4 to SR 7 and inverter transformer (IVT) The + common line of is configured to be connected to the upper and lower windings through the triac (T 5 ) (T 6 ) respectively.

콘덴서(C5), 코일(L2)(L3) 및 에스씨알(SCR7)(SCR8)은 정현파 보상용이다.The capacitor C 5 , the coils L 2 , L 3 , and SCR 7 (SCR 8 ) are for sine wave compensation.

Emergency는 내부소자가 작동치 않을때 입력전원을 직접 연결하는 것이다.Emergency is to connect input power directly when internal device is not working.

트라이악(T9), 에스씨알(SCR1)(SCR2)의 각 제어단자(T9, G9)(G1, K2)(G2, K2)는 평상시 온상태, 에스씨알(SCR3)(SCR4), 트라이악(T5)(T6)의 각 제어단자(G3, K3)(G4, K4), (G5, K5)(G6, K6)는 정전시 온상태, 에스씨알(SCR7)(SCR8) 각 제어단자(G7, K7)(G8, K8)는 항시 온으로 출력 레벨 설정, 트라이악(T10)의 제어단자(G10, K10)은 항상 온상태로 조정된다.Triac (T 9), S-CR (SCR 1), each control terminal of the (SCR 2) (T 9, G 9) (G 1, K 2) (G 2, K 2) are on normal state, S-CR ( SCR 3 ) (SCR 4 ), triac (T 5 ) (T 6 ) control terminals (G 3 , K 3 ) (G 4 , K 4 ), (G 5 , K 5 ) (G 6 , K 6 ) Is on at power failure, SCR 7 (SCR 8 ) each control terminal (G 7 , K 7 ) (G 8 , K 8 ) is always on, setting output level, triac (T 10 ) control Terminals G 10 and K 10 are always adjusted on.

이와 같이 구성된 본 고안은 평상시에는 입력전원을 매칭 트랜스(MT1)에 의한 2차권선의 AVR작용에 의한 설정전압으로 정현파 출력시킨다.The present invention configured as described above normally outputs the sine wave to the set voltage by the AVR action of the secondary winding by the matching transformer MT 1 .

이때, 충전부에서는 바테리(B)에 충전을 하게된다. 정전시에는 충전된 바테리(B)의 +직류전원이 인버터에 제공된다.At this time, the charging unit is charged to the battery (B). In case of power failure, the + DC power supply of the charged battery B is provided to the inverter.

이때, 에스씨알(SCR3)이 제어단자에 의하여 도통되었다면, +전원이 트라이악(T5), 인버터 트랜스(IVT)의 상부일차권선, 다이오드(SR4) 및 에스씨알(SCR3)에 인가되고, 에스씨알(SCR4)이 제어단자에 의하여 도통되었다면 +전원이 트라이악(T6), 인버터 트랜스(IVT)이 하부일차권선, 다이오드(SR7) 및 에스씨알(SCR4)에 인가되어 정현파를 형성하게 되는 것이다. 상기 트라이악(T5)(T6)은 에스씨알(SCR3)(SCR4)과 동기를 맞춰서 교대로 작동하지만 에스씨알(SCR3)(SCR4)이 중첩되게 도통된다 하여도 트라이악(T5)(T6)의 작동에 의하여 중첩되지 않고 정현파를 제공할수 있게 된다.At this time, if the SCR 3 is conducted by the control terminal, the + power is applied to the triac (T 5 ), the upper primary winding of the inverter transformer (IVT), the diode (SR 4 ) and the SCR 3 (SCR 3 ). If the SCR 4 is conducted by the control terminal, the + power is applied to the triac (T 6 ), the inverter transformer (IVT) is applied to the lower primary winding, the diode SR 7 and the SCR 4 . It will form a sine wave. The triac (T 5) (T 6) is S-CR (SCR 3) (SCR 4) and shift work as to match the synchronous but S. CR (SCR 3) (SCR 4) Tri-be are conductive to be an overlap Ill ( By the operation of T 5 ) (T 6 ) it is possible to provide a sine wave without overlapping.

다이오드(SR5)(SR6)는 역기전류방지용이고, 콘덴서는 에스시알(SCR3)(SCR4)의 온, 오프용 진상콘덴서이다.The diode SR 5 (SR 6 ) is for preventing counter current, and the capacitor is a phase-capacitor for on and off of esc (SCR 3 ) (SCR 4 ).

이와같이 본 고안은 평상시에는 입력전원을 매칭트랜스를 통한 출력을 사용하는 AVR로 동작하고, 정전시에만 인버터가 작동하므로 전기절약 효과가 높고, 소음이 평상시 거의 없으며, 파형이 완전 정현파로써 전압안정도가 대딘히 높은 초정밀급의 절전형 무정전 전원장치를 제공할 수 있는 것이다.As such, the present invention operates as an AVR using input power as an output through a matching transformer in normal times, and the inverter operates only during power outages, so it has high electric saving effect, almost no noise, and waveforms are perfectly sinusoidal, resulting in high voltage stability. It is possible to provide a very high-precision power-saving uninterruptible power supply.
