전압 조정 장치Voltage regulator

본 발명은 가변 볼륨을 이용하여 제어 전압을 조정하는 전압 조정장치에서 조정전압을 측정하고 그 측정된 조정전압에 따라 가장 최적의 제어전압을 설정하여 자동으로 조정전압을 출력토록 한 전압 조정 장치를 제공하는데 있다.The present invention provides a voltage adjusting device which measures the adjustment voltage in a voltage adjusting device that adjusts the control voltage using a variable volume and automatically sets the most suitable control voltage according to the measured adjusting voltage to automatically output the adjusting voltage. It is.

일반적으로, 모니터나 티브이 등의 영상기기의 생산시 임의의 제품 성능을 측정하기 위해서 조정 전압을 생성하게 되는데, 이때 가변 볼륨을 이용하여 조정 전압을 생성하는 방법이 일반적으로 사용된다.In general, in the production of a video device such as a monitor or TV, to generate an arbitrary voltage to measure the performance of the product, a method of generating a regulated voltage using a variable volume is generally used.

즉, 계측자가 가변 볼륨을 이용하여 조정전압을 생성하고, 그 조정전압을 계측기를 통해 계측한후 원하는 조정 전압이 아닐 경우에는 다시 계측기를 보면서 가변 볼륨을 수동으로 조작하여 원하는 조정전압을 설정하게 된다.That is, the instrument generates an adjustment voltage using the variable volume, and measures the adjustment voltage through the instrument, and if it is not the desired adjustment voltage, manually adjusts the variable volume while watching the instrument to set the desired adjustment voltage. .

따라서 전술한 바와같은 조정전압 생성방법은, 계측자가 계측기를 확인하면서 가변 볼륨을 수동으로 조작하여 원하는 조정전압을 생성하기 때문에 조정 시간이 오래 걸린다는 단점이 있으며, 또한 가변 볼륨을 수동으로 조정하여 조정전압을 생성하기 때문에 조정전압 생성에 정확성이 떨어지는 문제점도 있었다.Therefore, the above-described adjustment voltage generation method has a disadvantage in that the adjustment takes a long time because the instrument manually operates the variable volume while checking the measuring instrument to generate a desired adjustment voltage, and also adjusts the variable volume manually. Since the voltage is generated, there is a problem that the accuracy of generating the regulated voltage is poor.

이에 본 발명은 상기와 종래 조정전압 설정시 발생하는 제반 문제점을 해결하기 위해서 제안된 것으로, 본 발명의 목적은 가변 볼륨을 이용하여 제어 전압을 조정하는 전압 조정장치에서 조정전압을 측정하고 그 측정된 전압에 따라 가장 최적의 조정전압을 자동으로 설정하여 전압을 출력토록 한 전압 조정 장치를 제공하는데 있다.Accordingly, the present invention has been proposed to solve the above-mentioned problems occurring in setting the conventional regulated voltage, and an object of the present invention is to measure the regulated voltage in a voltage adjusting device for adjusting the control voltage using a variable volume and measure the measured voltage. It is to provide a voltage regulation device that automatically outputs the voltage by automatically setting the most optimal regulation voltage according to the voltage.

도1은 본 발명에 의한 전압 조정 장치 회로도이다. 이에 도시된 바와같이, 조정전압 출력부(20)로부터 출력되는 조정전압을 검출하고 그 검출치를 제어부(10)에 피이드백시키는 전압검출부(40)와, 상기 전압검출부(40)에서 검출된 전압과 출력코자하는 조정전압과의 차이를 산출하고 그 차이값만큼 펄스폭 변조신호를 가변시켜 출력하는 제어부(10)와, 상기 제어부(10)로부터 출력되는 펄스폭 변조신호에 따라 조정전압을 변화시켜 출력하는 조정전압 출력부(20)로 구성된다.1 is a circuit diagram of a voltage regulator according to the present invention. As shown therein, the voltage detector 40 detects the adjustment voltage output from the adjustment voltage output unit 20 and feeds the detected value back to the control unit 10, and the voltage detected by the voltage detection unit 40; A control unit 10 for calculating a difference with the adjustment voltage to be output and varying and outputting the pulse width modulation signal by the difference value, and changing the adjustment voltage according to the pulse width modulation signal output from the control unit 10 and outputting the result. It consists of the adjustment voltage output unit 20.

상기에서, 전압검출부(40)와 상기 전압출력부(20)사이에는 출력 전압을 검출하기 위한 탐침(30)이 구비된다.In the above, a probe 30 for detecting an output voltage is provided between the voltage detector 40 and the voltage output unit 20.

그리고 전압출력부(20)는 상기 제어부(10)에서 출력되는 펄스폭 변조신호를 증폭하는 증폭트랜지스터(TR)와, 상기 증폭트랜지스터(TR)에 의해 증폭된 전압을 역전류방지용 다이오드(D1)를 통해 전달받아 평활시켜주는 평활콘덴서(C1)로 구성된다.The voltage output unit 20 may further include an amplifying transistor TR for amplifying a pulse width modulated signal output from the controller 10, and a voltage amplified by the amplifying transistor TR for reverse current prevention diode D1. It consists of a smoothing capacitor (C1) to receive and smooth through.

이와 같이 구성된 본 발명에 의한 전압 조정 장치의 작용을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.The operation of the voltage adjusting device according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

먼저, 초기에 제어부(10)는 전압 조정을 위한 펄스폭 변조신호(PWM신호)를 출력시키게 되고, 전압출력부(20)는 그 출력되는 펄스폭 변조신호를 증폭트랜지스터(TR)로 증폭하고, 평활콘덴서(C1)로 평활시켜 조정전압(V)으로 후단에 출력시킨다. 여기서 증폭트랜지스터(TR)의 콜렉터 단자와 평활콘덴서(C1)사이에는 역전류 방지용 다이오드(D1)가 게재되어 역전류를 방지하게 된다.First, the controller 10 initially outputs a pulse width modulation signal (PWM signal) for voltage adjustment, and the voltage output unit 20 amplifies the output pulse width modulation signal with an amplifying transistor TR. Smoothed by the smoothing capacitor (C1) and output to the rear end with the adjustment voltage (V). Here, a reverse current prevention diode D1 is provided between the collector terminal of the amplifying transistor TR and the smoothing capacitor C1 to prevent reverse current.

상기와 같이 조정전압을 출력하는 상태에서 조정전압을 측정 및 조정하기 위해서 계측자는 본 발명에서 추가된 탐침(30)만을 조정값 출력단자에 접촉시킨다. 그러면 전압검출부(40)는 탐침(30)에 의해 검출되는 출력전압치를 계측하여 상기한제어부(10)에 피이드백시키게 되고, 제어부(10)는 그 피이드백되는 검출전압과 요구하는 조정전압간의 차이값을 산출한다. 그리고 그 산출한 차이 전압값만큼 펄스폭 변조신호를 변화시켜 출력시키게 된다. 이에 따라 전압출력부(20)는 이 변경된 펄스폭 변조신호에 따라 출력전압을 변화시킴으로써 자동으로 조정전압(V)을 변환시키게 되는 것이다.In order to measure and adjust the adjustment voltage in the state of outputting the adjustment voltage as described above, the measuring instrument contacts only the probe 30 added in the present invention to the adjustment value output terminal. Then, the voltage detector 40 measures the output voltage value detected by the probe 30 and feeds it back to the controller 10, and the controller 10 controls the difference between the detected detection voltage and the required adjustment voltage. Calculate the value. The pulse width modulation signal is changed and output as much as the calculated difference voltage value. Accordingly, the voltage output unit 20 automatically converts the adjustment voltage V by changing the output voltage according to the changed pulse width modulation signal.

상기에서 펄스폭 변조신호의 가변은 제어부(10)의 내부에 메모리를 구비하고 그 메모리에 이미 실험으로 얻어진 가변값을 룩업 테이블 형식으로 저장하고, 상기와 같이 검출치와 요구치의 차이값만 산출되면 그 차이값만을 룩업 테이블에 대비시켜 원하는 펄스폭 변조신호를 얻게되는 것이다.The variable of the pulse width modulation signal is provided with a memory inside the control unit 10 and stores the variable value obtained by experiment in the memory in the form of a look-up table, and only the difference between the detected value and the required value is calculated as described above. Only the difference is compared to the lookup table to obtain the desired pulse width modulated signal.

이상에서 상술한 바와같이 본 발명은 임의의 부품 기능 테스트를 위한 전압의 조정시 출력 조정전압을 측정하고 그 측정치와 요구하는 요구치를 자동으로 비교하여 그 결과치에 따라 출력되는 조정전압을 가변토록 자동으로 펄스폭 변조신호를 가변시킴으로써 조정전압 계측 및 측정을 간단한 조작(탐침을 출력단자에 접촉시키는 조작)에 의해서 자동으로 전압 조정을 수행함으로써 기존과 같은 수동조작에 따른 계측 및 조정의 불편함을 해소시킴과 아울러 조정자의 작업량을 저감시킬 수 있는 효과가 있다.As described above, the present invention measures the output adjustment voltage when adjusting the voltage for any component function test, automatically compares the measured value with the required value, and automatically adjusts the output voltage according to the resultant variable. By adjusting the pulse width modulated signal, the adjustment of voltage measurement and measurement is performed automatically by simple operation (operation of contacting the probe to the output terminal), eliminating the inconvenience of measurement and adjustment by manual operation. In addition, there is an effect that can reduce the amount of work of the coordinator.

또한 비교 및 차이전압 산출을 마이컴(제어부)을 통해 수행함으로써 정확성을 기할 수 있는 효과도 있다.In addition, the comparison and the calculation of the difference voltage through the microcomputer (control unit) also has the effect of ensuring the accuracy.
