본 고안은 VTR의 전원회로에 관한 것으로, 특히 차량에다 설치하게 되는 VTR의 전원을 자동차에서 발전되는 교류전원과 차량에 설치된 축전지의 직류전압을 함께 쓸 수 있도록된 VTR의 전원회로에 관한 것이다.The present invention relates to a power supply circuit of a VTR, and more particularly, to a power supply circuit of a VTR, which enables the power supply of a VTR installed in a vehicle to be used together with an alternating current power source generated in an automobile and a direct current voltage of a battery installed in the vehicle.

현재 VTR은 교통수단인 차량에도 설치하고 있을 정도로 널리 보급되고 있는 상황에 있고, 그에 따라 차량에 설치하게 되는 VTR을 구동시키기 위해 종래에는 제1도에 도시된 바와 같이 트랜스(T1)와 브리지정류회로(BD1), 전압안정기(VR1) 및 축전지 연결잭(BJ1)등을 결합시켜 구성한 VTR의 전원회로를 채용하므로서 차량으로 부터 발전되는 교류전원을 트랜스(T1)와 브리지정류회로(BD1)에다 인가하여 정류시킨 다음, 전압안정기(VR1)에 공급하여 일정한 직류전원(13V)을 발생시켜 VTR을 구동시키도록 되어 있었다.Current VTR is in a situation which is widely spread enough, and installation in transport vehicles, transport (T 1) and a bridge rectifier, as shown in FIG. 1, the prior art to drive the VTR is installed in a vehicle accordingly By adopting the power supply circuit of the VTR formed by combining the circuit (BD 1 ), voltage stabilizer (VR 1 ), and battery connection jack (BJ 1 ), the AC power generated from the vehicle is transferred to the transformer (T 1 ) and the bridge rectifier circuit (BD). 1 ) and then rectified and supplied to the voltage stabilizer VR 1 to generate a constant DC power supply 13V to drive the VTR.

그러나 이와 같은 종래의 VTR구동전원을 얻는 방법에서는 차량에서 발전되는 교류전원만을 허용하여 VTR을 작동시키도록 되어 있었기 때문에 차량의 시동을 짧은 시간동안 중지 시켜야 할 필요가 있을 때에는 차량의 교류발전이 중단됨에 따라 VTR도 동작을 중지시켜야 하는 문제가 있었을 뿐만 아니라 그에 따라 차량용 VTR의 보급을 저해시키는 요인이 되고 있었다.However, in the conventional method of obtaining the VTR driving power, the VTR is operated by allowing only the AC power generated by the vehicle. Therefore, when the vehicle needs to be stopped for a short time, the AC power generation of the vehicle is stopped. Therefore, not only the VTR has to stop the operation, but also has been a factor that inhibits the spread of the vehicle VTR.

이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 고안된 것으로서, 차량에서 발전되는 교류전원과 차량의 축전지에서 출력되는 직류전원을 모두 VTR의 구동전원으로 사용할 수 있도록 특히 제너다이오드를 사용하여 승용차나 버스와 트럭등에 사용되는 축전지의 직류전압(13[V]와 24[V])이 다르게 되어 있더라도 VTR에 공급되는 직류전압을 일정전압으로 변환시켜서 VTR을 구동시키도록 된 VTR의 전원회로를 제공하고자 안출된 것이다.Therefore, the present invention is designed to solve the above problems, and in particular, a Zener diode is used to drive both the AC power generated from the vehicle and the DC power output from the battery of the vehicle as the driving power of the VTR. Even though the DC voltages (13 [V] and 24 [V]) of storage batteries used in trucks are different, it is designed to provide a power circuit of VTR which converts the DC voltage supplied to the VTR to a constant voltage to drive the VTR. will be.

이하 본 고안의 구성 및 작용, 효과를 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 교류전원이 입력되는 트랜스(T2)에 콘덴서(C2)를 매개하여 브리지정류회로(BD1)가 접속되고 상기 브리지정류회로(BD1)에는 콘덴서(C3)와 전압안정기(VR1) 및 축전지 연결잭(BJ1)이 차례로 접속되며, 상기 축전지 연결잭(BJ1)에는 저항(R1)과 제너다이오드(ZD1)를 매개하여 트랜지스터(TR1)의 베이스가 연결됨과 더불어 다이오드(D1)와 릴레이(RY1)의 접점(a)이 각각 접속되고, 상기 릴레이(RY1)의 접점(C)(C′)사이에는 전압안정기(VR2)가 연결되며, 접점(a′)에는 콘덴서(C4)를 매개하여 코일(L1)과 콘덴서(C4)로 된 평활회로가 접속되고, 상기 코일(L1)과 콘덴서(C5)의 평활회로에는 직류전압단(13V)과 전원감지단(PD)이 연결된 구조로 되어 있다.The subject innovation is the capacitor (C 3) and a voltage stabilizer connected to a bridge rectifier (BD 1) to mediate a capacitor (C 2) to the transformer (T 2) that the AC power input and the bridge rectifier circuit (BD 1) ( VR 1 ) and the battery connection jack BJ 1 are sequentially connected to each other, and the base of the transistor TR 1 is connected to the battery connection jack BJ 1 via a resistor R 1 and a zener diode ZD 1 . A contact point (a) of the relay (D 1 ) and the relay (RY 1 ) are respectively connected, and a voltage stabilizer (VR 2 ) is connected between the contact point (C) (C ′) of the relay (RY 1 ), the contact point (a) '), the smoothing circuit has a DC voltage terminal of the intermediate capacitor (C 4), a coil (L 1) and capacitor (C 4) and the smoothing circuit is connected to the coil (L 1) and capacitor (C 5) ( 13V) and power detection terminal (PD) are connected.

제2도는 상기한 구조로 되어 있는 본 고안의 회로도로서, 교류전원과 직류전원의 사용에 대하여 설명하면, 먼저 자동차에서 발전된 교류전원이 입력되면 트랜스(T1)에서는 유기 기전력이 발생되어 브리지정류회로(BD1)에 공급되어 전파 정류 된 후에 콘덴서(C2)를 통과하면서 평활하게 된다.FIG. 2 is a circuit diagram of the present invention having the above-described structure. Referring to the use of an AC power source and a DC power source, first, when an AC power source generated in a vehicle is input, an organic electromotive force is generated in a transformer (T 1 ) so that the bridge rectifier circuit After supplying to BD 1 and full-wave rectifying, it is smoothed while passing through the capacitor C 2 .

이때의 전압은 입력전압과 부하에 따라 그 변동이 심하게 일어나게 되므로 전압안정기(VR1)를 사용하여 안정된 정전압(13[V])으로 변환시키게 된다.At this time, since the voltage fluctuates depending on the input voltage and the load, the voltage stabilizer VR 1 is used to convert the voltage into a stable constant voltage 13 [V].

따라서, 이 전압은 정전압(13[V])은 축전지 연결잭(BJ1)과 릴레이(RY1)의 접점(a-b)(a′-b′)을 통하여 코일(L1)과 콘덴서(C5)로 된 자동차 잡음 제거용 필터에 인가된다.Therefore, this voltage is a constant voltage (13 [V]) is the coil (L 1 ) and the capacitor (C 5 ) through the contacts (ab) (a'-b ') of the battery connection jack (BJ 1 ) and the relay (RY 1 ) Is applied to the vehicle noise canceling filter.

그러므로 정전압 (13[V])은 더욱 안정되어 VTR에 입력되게 된다.Therefore, the constant voltage 13 [V] is further stabilized and input to the VTR.

이때, 제너다이오드(ZD1)의 정격전압을 15[V]로 하게되면 제너다이오드(ZD1)는 역전류가 흐르지 못하게 되어 오프 상태로 있게 됨에 따라 트랜지스터(TR1)도 턴 오프상태를 유지하게 된다.At this time, when the rated voltage of the zener diode ZD 1 is set to 15 [V], the zener diode ZD 1 is turned off because no reverse current flows, so that the transistor TR 1 also remains turned off. do.

다음에 승용차에 설치된 측전지의 직류전압(13[V])에 의해 VTR을 구동시키는 경우에는 승용차 축전지의 코드를 축전지 연결잭(BJ1)에 결합시키게 되면 회로는 교류전원이 차단되게 된다.Next, when the VTR is driven by the DC voltage 13 [V] of the side battery provided in the passenger car, when the cord of the passenger car battery is coupled to the battery connection jack BJ 1 , the AC power is cut off.

이때에도 제너다이오드(ZD1)에는 역전류가 흐르지 못하므로 트랜지스터(TR1)는 턴오프되고, 그에 따라 릴레이(RY1)의 코일에도 전류가 흐르지 않게 되므로 릴레이(RY1)는 접점(a-b)(a′-b′)에 연결되어 승용차의 축전지에서 출력되는 전압(13[V])이 VTR에 공급되어진다.In this case also, because the zener diode (ZD 1) is because the reverse current that can not flow through the transistor (TR 1) is turned off and thereby the current in the coil of the relay (RY 1) it does not flow along the relay (RY 1) is a contact point (ab) The voltage 13 [V] output from the battery of the passenger car connected to (a'-b ') is supplied to the VTR.

또한, 대형 버스의 축전지에서 출력되는 직류전압(24[V])을 사용하여 VTR을 구동시키게 되면 축전지의 코드를 축전지 연결잭(BJ1)에 연결시킨다.In addition, when the VTR is driven using the DC voltage 24 [V] output from the battery of the large bus, the cord of the battery is connected to the battery connection jack BJ 1 .

따라서, 버스축전지로 부터는 24[V]의 직류전압이 입력되고, 제너다이오드(ZD1)에는Therefore, a direct current voltage of 24 [V] is input from the bus storage battery, and the zener diode (ZD 1 ) is inputted.

로 되는 역전류가 흐르게 되어 트랜지스터(TR1)의 베이스에 공급되므로 트랜지스터(TR1)가 턴온된다. 이때, 릴레이(RY1)의 코일에도 전류가 흐르게 되어 릴레이(RY1)의 접점은(a-c)(a′-c′)로 접속된다.Since the reverse current that flows to supply the base of the transistor (TR 1) it is turned on and the transistor (TR 1). At this time, in the coil of the relay (RY 1) flows, the current is contact of the relay (RY 1) is connected to (ac) (a'-c ' ).

따라서, 버스축전지의 직류전압(24[V])은 전압안정기(VR2)로 공급되며, 그에 따라 전압안정기(VR2)에서는 직류전압을 13[V]로 변환시켜서 자동차 잡음제거용 필터회로를 구성하는 코일(L1)과 콘덴서(C5)를 거쳐서 출력되게 된다.Thus, the direct current voltage (24 [V]) of the bus, the battery is supplied to the voltage regulator (VR 2), whereby the voltage stabilizer (VR 2) In a direct-current voltage 13 [V] by converting to a filter circuit for removing car noise The coil L 1 and the condenser C 5 are configured to be output.

이때, 다이오드(D1)는 릴레이(RY1) 복귀시에 역기전력을 방전시켜 트랜지스터(TR1)를 보호하게 된다.At this time, the diode D 1 protects the transistor TR 1 by discharging the counter electromotive force upon the return of the relay RY 1 .

상기한 바와 같이 본 고안은 차량에 설치된 VTR에 공급되는 전원을 교류와 차량의 축전지에서 출력되는 직류전압을 겸용하도록 되어 있으며, 또한 차량의 축전지에서 출력되는 직류전압에 따라 자동으로 전압을 안정화 시키도록 되어 있음에 따라 VTR을 자동차등의 차량에 설치하고자 하는 경우에 차량의 종류나 VTR의 구동전원을 선별하지 않고서 차량에서 발전되는 교류와 축전지의 직류를 혼용할 수 있게 되는 효과가 있다.As described above, the present invention is designed to combine the power supplied to the VTR installed in the vehicle with the alternating current and the DC voltage output from the vehicle's battery, and to automatically stabilize the voltage according to the DC voltage output from the vehicle's battery. Therefore, when the VTR is to be installed in a vehicle such as an automobile, there is an effect that the alternating current generated in the vehicle and the direct current of the battery can be mixed without selecting the type of the vehicle or the driving power of the VTR.
