본고안은 자동차교류발전기의 전압검출 및 온도보상장치에 관한 것으로서, 더욱 상세히는 선택적인 구성의 전압검출 및 온도보상장치를 구비하는 교류발전기의 전압조정기에 관한 것이다.The present invention relates to a voltage detection and temperature compensation device of an automotive alternator, and more particularly, to a voltage regulator of an alternator having a voltage detection and temperature compensation device of an optional configuration.
자동차용 교류발전기의 기전력을 조정하기 위하 전압조정기에 있어서, 종래에는 전압검출방식으로서 발전기의 출력전압을 검출하거나 또는 밧데리전압을 직접 단일 검출하는 방식을 사용하였다.In the voltage regulator for adjusting the electromotive force of the automotive alternator, a voltage detection method has conventionally used a method of detecting an output voltage of a generator or directly detecting a battery voltage.
상기와 같은 종래의 구성의 경우 밧데리 단자의 단선시에 발전기의 출력 전압검출로 자동전환되게 되나, 조정전압이 높고 불안정한 전원 상태를 가지는 문제점이 있고 조정시의 온도의 변동에 따른 보상치를 고려하지 못한다는 문제점이 있었다.In the conventional configuration as described above, when the battery terminal is disconnected, the output voltage of the generator is automatically switched, but there is a problem that the control voltage is high and the power supply is unstable, and the compensation value due to the temperature change during adjustment is not considered. Had a problem.
상기와 같은 문제점을 감안하여 밧데리전압을 직접 검출할 수 있고 밧데리 단자의 단선시에 발전기 출력전압의 자동전환 검출이 가능하고 온도보상이 가능하여 밧데리의 효율적인 충전이 가능한 자동차교류발전기의 전압검출 및 온도보상장치를 제공하는 것을 본고안의 목적으로 한다.In consideration of the above problems, it is possible to directly detect the battery voltage, to automatically detect the generator output voltage when the battery terminal is disconnected, and to compensate for the temperature, so that the battery can be charged efficiently. It is an object of this proposal to provide a compensation device.
이하의 부수된 도면과 함께 본고안의 자동차교류발전기의 전압검출 및 온도보상장치를 더욱 상세히 설명한다.The voltage detection and temperature compensation device of the automotive alternator of the present invention together with the accompanying drawings will be described in more detail.
제1도는 본고안의 자동차교류발전기의 전압검출 및 온도보상장치를 도시하는 회로도로서 하나의 실시예로서 설명한다.FIG. 1 is a circuit diagram showing a voltage detection and temperature compensation device of an automotive alternator in this paper, which will be described as an embodiment.
본고안의 자동차교류발전기의 전압검출 및 온도보상장치는 종래의 전압조정기에 연결되어 사용되는 부분적인 부가구성으로서;The voltage detecting and temperature compensating device of the alternating current alternator of the present invention is a partial additional configuration used in connection with a conventional voltage regulator;
본고안은 밧데리의 전압을 검출하는 방식은 외부검출(External sensing)과 발전기의 출력전압을 검출하는 방식인 내부검출(Internal Sensing)의 2가지의 측정방식을 선택적으로 수행하게 하여, 밧데리측 또는 발전기측의 어느 하나를 출력전압으로 설정하는 스위칭구성으로서,In this paper, the battery voltage or the method of detecting the battery is internal sensing (Internal Sensing), which is a method of detecting the output voltage of the generator (External sensing) and selectively detects the battery side or generator As a switching configuration for setting any one of the sides to an output voltage,
밧데리전압인 외부전압의 검출은 특정전압값 이상에서 동작하게 하며 외부검출선이 단선되거나 특정전압이하로 내려가면 자동적으로 외부검출로 전환된다.The detection of the external voltage, which is the battery voltage, operates above the specified voltage value and automatically switches to the external detection when the external detection line is disconnected or falls below the specified voltage.
부가적으로 온도에 따른 밧데리의 효율적인 충전을 위하여 온도증가시 조정전압을 낮추는 온도보상회로를 가진다.In addition, it has a temperature compensation circuit that lowers the control voltage as the temperature increases for efficient charging of the battery according to the temperature.
밧데리로부터 인입되는 외부검출단자(101)의 전압이 일정 전압이상이면 트랜지스터(Q27)가 on되어 발전기측 출력전압이 발전기출력단자(102)로부터 트랜지스터(Q22)의 베이스에 가해지지 않으므로 외부검출단자(101)의 전압이 트랜지스터(Q19, Q21, Q25)를 거쳐 출력단자(103)로 검출된다.When the voltage of the external detection terminal 101 drawn from the battery is higher than or equal to a predetermined voltage, the transistor Q27 is turned on so that the output voltage of the generator side is not applied from the generator output terminal 102 to the base of the transistor Q22. The voltage of 101 is detected by the output terminal 103 via the transistors Q19, Q21, Q25.
또한, 외부검출선인 밧데리측결선이 단선되면 트랜지스터(Q19, Q20, Q21, Q27)가 off되어 자동적으로 발전기출력단자(102)의 전압이 트랜지스터(Q28, Q22, Q26, Q25)를 거쳐 출력단자(103)에 검출된다.In addition, when the battery side connection, which is an external detection line, is disconnected, the transistors Q19, Q20, Q21, and Q27 are turned off, and the voltage of the generator output terminal 102 is automatically passed through the transistors Q28, Q22, Q26, and Q25. 103 is detected.
한편 온도보상은 다이오우드(D2,...D14, Q26)와 트랜지스터(Q19, Q21, Q22, Q24, Q25, Q28)의 온도대 전압특성을 이용하는 것으로서 온도가 증가함에 따라서 다이오우드와 트랜지스터의 강하되는 전압이 감소하여 출력단자(103)의 전압이 증가하게 되므로 도시하지 아니하는 전압 조정기의 필드구동 트랜지스터(Field Driver Tr.)가 스위칭되는 전압이 낮아짐으로서 보상이 이루어지는 것이다.On the other hand, temperature compensation uses temperature vs. voltage characteristics of diodes (D2, D14, Q26) and transistors (Q19, Q21, Q22, Q24, Q25, Q28), and the voltage drop of diode and transistor as temperature increases. Since the voltage of the output terminal 103 decreases due to this decrease, compensation is performed by lowering the voltage at which the field driver transistor (Field Driver Tr.) Of the voltage regulator (not shown) is switched.
이상과 같은 본고안의 자동차교류발전기의 전압검출 및 온도보상장치는 밧데리 및 발전기의 전압검출을 선택적으로 선정하고 온도보상을 수행함으로서 최적의 차량 전압의 조정이 가능하게 하여 각종 차량 전장품의 작동의 안전성을 제고하는 유용한 고안인 것이다.As described above, the voltage detection and temperature compensation device of the alternating current alternating current generator selectively selects the voltage detection of batteries and generators and performs temperature compensation to enable the optimal adjustment of the vehicle voltage, thereby improving the safety of the operation of various vehicle electrical equipment. It is a useful design to enhance.
