A low voltage, rectified and smoothed to supply a DC power supply, and a transistor (Q 1 ), zener diode (ZD 1 ), capacitor (C 2 -C 3 ), etc. ), The first constant voltage circuit unit 2 and the zener diode ZD 2 for supplying constant voltage to the tuner unit 3, the pay system, the reserved recording unit 4, the microcomputer 5, etc. , Resistor (R 2 ), transistor (Q 2 ), capacitor (C 4 ) (C 5 ), etc., adjusts the output power of power supply unit 1 to the required voltage to adjust luminance and color signal processing unit 7, audio signal processing unit (8) whether the second voltage circuit section 6 supplied to the motor driving section 9, etc., and the VCR are operated or not; Stage to the second constant voltage the microcomputer (5) for controlling the operation of the circuit portion 6, a transistor (Q 3) (Q 4) as made for switching the second constant voltage circuit 6 under the control of microcomputer 5, etc. It consists of a switching unit (10).

이와같이 구성되는 종래의 VCR 전원공급장치의 동작은 다음과 같다.The operation of the conventional VCR power supply configured as described above is as follows.

파워코드에 의해 입력되는 상용전압(Ac 100-240V)은 전원공급부(1)의 트랜스포머(T1)의 1차축과 2차축 코일의 권선비에 의해 출력전압이 결정되어지고 이 출력은 브릿지다이오드(BD1)에 의해 전파정류되어 커패시터(C1)에 의해 평활되어 직류전압(DC)으로 변경되어 출력된다.The commercial voltage (Ac 100-240V) input by the power cord is determined by the winding ratio of the primary and secondary shaft coils of the transformer T 1 of the power supply unit 1, and the output is a bridge diode (BD). It is full-wave rectified by 1 ), smoothed by the capacitor C 1 , and converted into a DC voltage DC and output.

전원공급부(1)에서 출력된 직류전압은 제1, 제2정전압회로부(2)(6)를 거쳐 조정된 정전압으로 변경되어 지는데 제1정전압회로부(2)는 저항(R1)의 바이어스 저항에의해 제너다이오드(ZD1)과 트랜지스터(Q1)의 베이스에 적절한 전류를 공급하고 제너다이오드(ZD1)의 제너전압에 의해 출력직류전압이 결정되어지며 트랜지스터(Q1)의 에미터전압은 제너다이오드(ZD1)의 제너전압보다 0.7V×2의 전압이 드롭(Drop)되어 출력되어진다.The DC voltage output from the power supply unit 1 is changed to the constant voltage adjusted through the first and second constant voltage circuit units 2 and 6, and the first constant voltage circuit unit 2 is controlled by the bias resistance of the resistor R1. emitter voltage of the zener diode (ZD 1) and the transistor becomes is supplied to the appropriate current to the base of (Q 1) and to determine the output DC voltage by the Zener voltage of the Zener diode (ZD 1) the transistor (Q 1) is a Zener diode The voltage of 0.7V × 2 is dropped and output than the Zener voltage of (ZD 1 ).

또한 제2정전압회로부(6)는 트랜지스터(Q2), 저항(R2), 제너다이오드(ZD2), 커패시터(C4-C5)의 동작은 제1정전압회로부(2)와 동일하며 트랜지스터(Q2)의 베이스는 스위칭부(10)의 트랜지스터(Q3)(Q4)에 의해 온/오프된다.In addition, the operation of the second constant voltage circuit unit 6 is the same as that of the first constant voltage circuit unit 2 in the operation of the transistor Q 2 , the resistor R 2 , the zener diode ZD 2 , and the capacitor C 4 -C 5 . The base of Q 2 is turned on / off by transistors Q 3 and Q 4 of the switching unit 10.

그리고 스위칭부(10)는 마이컴(5)에서 제어되는 파워콘트롤신호가 하이일 때 트랜지스터(Q4)가 턴온되어 트랜지스터(Q3)의 베이스를 로우로 만들어 트랜지스터(Q3) 에미터에 걸리는 전압이 콜렉터로 도통되어 제너다이오드(ZD2) 전압이 트랜지스터(Q2)의 에미터로 출력되도록 하여 제2정전압회로부(6)가 휘도/색신호처리부(7), 오디오신호처리부(8)등에 직류전원을 공급하도록 하고, 파워콘트롤신호가 로우일때는 제2정전압회로부(6)가 직류전원을 공급하지 못한다.And the switching section 10 is a voltage applied to the microcomputer 5, the power control signal is at a high work when the transistor (Q 4) are turned on creating a base of the transistor (Q 3) to a low transistor (Q 3) which is controlled by the emitter This collector is conducted so that the zener diode (ZD 2 ) voltage is output to the emitter of the transistor Q 2 so that the second constant voltage circuit section 6 is connected to the luminance / color signal processing section 7, the audio signal processing section 8, and the like. When the power control signal is low, the second constant voltage circuit unit 6 cannot supply DC power.

그러나 이와같은 종래의 VCR 전원공급회로에 있어서는 오퍼레이트 파워오프 또는 스탠-바이시 휘도/색신호처리부, 오디오신호처리부 등은 정전압 공급이 마이콤의 제어에 의하여 차단되어지나, VPS(Video Program System) 예약녹화, ACSS Plus(AUTO Clock Sett-ing System Plus)등과 같은 기능이 있는 VCR에서 예약기능이 설정될 경우, 오퍼레이트 파워오프 모드나 온 모드 등 어느 경우에도 상기 기능을 수행하기 위해서는 방송신호를 수신해야 하므로 튜너부(3)와 유료시스템 및 예약녹화부(4)등에 향상 직류전원을 공급해야만 했다.However, in the conventional VCR power supply circuit, the constant power supply or the standby-by-brightness / color signal processing unit, the audio signal processing unit, etc., the constant voltage supply is cut off by the control of the microcomputer, but the VPS (Video Program System) reservation recording , If the reservation function is set in a VCR with functions such as ACSS Plus (AUTO Clock Set-ing System Plus), the broadcast signal must be received in order to perform the above functions in any of the operating power off mode and on mode. Improved DC power had to be supplied to the tuner section 3, the pay system and the reservation recording section 4, and the like.

따라서 오퍼레이트 파워오프 모드에서도 세트의 전력이 소모되므로 소비자의 부담 및 에너지 낭비의 요인이 되었으며 제품의 수명에도 악 영향을 주는 문제점이 있었다.Therefore, the power consumption of the set is consumed even in the operating power off mode has become a factor of consumer burden and energy waste, and also has a problem that adversely affects the life of the product.

이와같이 구성된 본 발명의 그린파워기능을 갖는 VCR 전원공급장치의 동작은 다음과 같다.Operation of the VCR power supply having a green power function of the present invention configured as described above is as follows.

제3도는 본 발명의 그린파워기능을 갖는 VCR 전원공급장치의 각부 파형도이고, 제4도는 본 발명의 동작 순서도로써, 파워코드에 의해 입력되는 상용전압(Ac 100∼240V)은 전원공급부(21)의 트랜스포머(T1)의 1차측과 2차측 코일의 권선비에 의해 출력전압이 결정되어지며 이 출력은 브릿지다이오드(BD1)에 의해 전파류되고 커패시터(C1)에 의해 평활되어 직류전압(DC)으로 변경되어 출력된다.3 is a waveform diagram of each part of the VCR power supply having a green power function according to the present invention, and FIG. 4 is a flowchart illustrating the operation of the present invention, and the commercial voltage (Ac 100 to 240 V) input by the power cord is the power supply unit 21. The output voltage is determined by the turns ratio of the primary and secondary coils of the transformer (T 1 ) of the transformer, and this output is propagated by the bridge diode (BD 1 ) and smoothed by the capacitor (C 1 ) The output is changed to DC).

전원공급부(21)에 출력된 직류전압은 제1, 제2, 제3정전압회로부(22)(23)(28)에 의해 정전압으로 조정되어 각부에 출력된다.The DC voltage output to the power supply 21 is adjusted to a constant voltage by the first, second and third constant voltage circuits 22, 23 and 28 and output to each part.

즉, 제1정전압회로부(22)는 저항(R1)의 바이어스 저항에 의해 제너다이오드(ZD1)와 트랜지스터(Q1)의 베이스에 적절한 전류를 공급하고 제너다이오드(ZD1)의 제너전압에 의해 출력직류전압이 결정되어지며 트랜지스터(Q1)의 에미터전압은 제너다이오드(ZD1)의 제너전압보다 0.7×2의 전압이 드롭되어 출력된다.That is, the first constant voltage circuit unit 22 supplies an appropriate current to the base of the zener diode ZD 1 and the transistor Q 1 by the bias resistance of the resistor R 1 and to the zener voltage of the zener diode ZD 1 . The output DC voltage is determined, and the emitter voltage of the transistor Q 1 is output by dropping a voltage of 0.7 × 2 from the zener voltage of the zener diode ZD 1 .

그 밖의 제2, 제3정전압회로부(23)(28)도 제1정전압회로부(22)와 마찬가지로 정전압을 출력한다.The second and third constant voltage circuit units 23 and 28 also output a constant voltage similarly to the first constant voltage circuit unit 22.

이때 마이콤(32)은 파워의 온/오프를 판단하고 파워온 시는 제3도와같이 제2, 제3정전압회로부(23)(28)가 동작되어 정전압을 모터서보부(24), 휘도/색신호처리부(25), 오디오신호처리부(26), 튜너부(29), 유료시스템 및 예약기능부(30)등에 공급하도록 파워콘트롤신호 및 그린파워콘트롤신호를 제1, 제2스위칭부(27)(31)에 하이로 출력한다.At this time, the microcomputer 32 determines whether the power is on or off, and when the power is on, the second and third constant voltage circuit units 23 and 28 operate as shown in FIG. 3 to convert the constant voltage to the motor servo unit 24 and the luminance / color signal. The first and second switching units 27, which supply power control signals and green power control signals to the processor 25, the audio signal processor 26, the tuner 29, the pay system and the reservation function 30, etc. 31) High.

그리고, 파워오프일 경우 예약기능이 설정되어 있는가를 판단한다.In the case of power-off, it is determined whether the reservation function is set.

예약기능이 설정되어 있으면, 그린파워콘트롤신호를 제3도(b)와 같이 펄스신호를 출력하여 펄스신호가 하이일 때 제2스위칭(31)의 트랜지스터(Q5)(Q6)가 턴온되어 제3정전압회로부(28)에 전원공급부(21)의 직류전원이 공급되도록 하여 튜너부(29)와 예약기능설정부(30)에 정전압이 공급되도록 하고, 펄스신호가 로우일 때 제2스위칭부(31)의 트랜지스터(Q5)(Q6)가 턴오프되어 제3정전압회로부(28)에 전원공급부(21)의 직류전원이 공급되지 않도록하여 튜너부(29)와 예약기능설정부(30)에 정전압이 공급되지 않도록한다.If the reservation function is set, the third also outputs a pulse signal as shown in (b) the transistor (Q 5) (Q 6) of the second switch 31 is turned on when the pulse signal is at a high green power control signal The DC power of the power supply unit 21 is supplied to the third constant voltage circuit unit 28 so that the constant voltage is supplied to the tuner unit 29 and the reservation function setting unit 30, and the second switching unit when the pulse signal is low. The transistor Q 5 and Q 6 of 31 are turned off so that the DC power of the power supply unit 21 is not supplied to the third constant voltage circuit unit 28 so that the tuner unit 29 and the reservation function setting unit 30 are maintained. ) Do not supply constant voltage.

이와같이 마이콤(32)에서 예약기능 설정시에 펄스신호를 출력하여도 튜너부(29) 및 예약설정부(30)는 동작한다.In this way, even when the microcomputer 32 outputs a pulse signal when setting the reservation function, the tuner unit 29 and the reservation setting unit 30 operate.

그리고, 파워오프시 예약기능이 설정되어 있지않을 경우에는 그린파워콘트롤신호를 제3동(c)와 같이 로우신호를 출력하여 제3정전압회로부(28)에서 정전압이 출력되지 못하도록 한다.When the reservation function is not set when the power is off, the green power control signal is output as a low signal as in the third operation (c) to prevent the constant voltage from being output from the third constant voltage circuit unit 28.

마이콤(32)의 파워콘트롤신호는 파워 온/오프에 따라 파워온 시는 하이신호가 출력하고 파워오프 시에는 로우신호를 출력하여 불필요한 소비전력을 줄인다.The power control signal of the microcomputer 32 outputs a high signal at power-on according to power on / off and outputs a low signal at power-off to reduce unnecessary power consumption.

결과적으로 본 발명의 그린파워 장치는 정전압회로부를 3개로 구성하여 마이콤(32)에는 항상 정전압이 공급되도록 하고, 모터서보부(24), 휘도/색신호처리부(25), 오디오신호처리부(26)등에는 파워오프 시에는 정전압이 공급되지 않고 파워온 시에만 정전압이 공급되도록 마이콤(32)이 제어하며, 튜너부(29) 및 예약설정부(30)에는 파워오프 시에 예약기능이 설정되어 있느냐를 판단하고 설정되어 있으면 일정주기의 펄스신호를 출력하여 정전압이 일정주기로 공급되도록 하고, 예약기능이 설정되어 있지 않으면 정전압이 공급되지 않도록 마이콤(32)이 제어한다.As a result, the green power device of the present invention comprises three constant voltage circuits so that the constant voltage is always supplied to the microcomputer 32, and the motor servo unit 24, the luminance / color signal processing unit 25, the audio signal processing unit 26, and the like. Is controlled by the microcomputer 32 such that the constant voltage is not supplied at power-off but is supplied only at power-on, and whether the reservation function is set at the time of power-off in the tuner unit 29 and the reservation setting unit 30. If it is determined and set, the pulse signal of a certain period is outputted so that the constant voltage is supplied at a constant period, and if the reservation function is not set, the microcomputer 32 controls the constant voltage to not be supplied.

이상에서 설명한 바와같은 본 발명의 그린파워 장치에 있어서는 오페레이트 파워오프 모드 혹은 스탠-바이 모드에서 특정시스템 블럭(튜너부 VPS 예약녹화, ACCS Plus 등)에 항상 전원을 공급하지 않고 예약기능이 설정되었을 경우는 일정시간 주기로 전원이 공급되도록 하고 예약기능이 설정되지 않았을 경우는 전원을 공급하지 않으므로, 종래의 특정시스템 블럭에 항상 전원을 공급할때보다 소비전력이 현저하게 감소하게 되고 제품의 수명을 연장할 수 있다.In the green power device of the present invention as described above, the reservation function may be set without always supplying power to a specific system block (tuner VPS reservation recording, ACCS Plus, etc.) in the operating power off mode or standby mode. In this case, power is supplied at regular intervals, and when the reservation function is not set, power is not supplied. Therefore, power consumption is significantly reduced and the life of the product can be prolonged. Can be.

뿐만 아니라 이와같은 그린파워시스템을 전기전자 기기에 적용하면 획기적으로 전력소모를 감소하는 효과가 있다.In addition, the application of such a green power system to electrical and electronic equipment has the effect of dramatically reducing power consumption.
