이하 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail.
도 1에는 본 발명의 일 실시예에 따른 자동차용 전원 회로가 도시되어 있다. 도면을 참조하면, 본 실시예에 따른 자동차용 전원 회로는, 자동차용 발전기(1)로부터 개별적이고 독립적인 전원들을 생성하여, 각 부하(13, 14, 15)에 공급하도록 되어 있다.1 shows an automotive power supply circuit according to an embodiment of the present invention. Referring to the drawings, the automotive power supply circuit according to the present embodiment is configured to generate individual and independent power sources from the automotive generator 1 and supply them to the respective loads 13, 14, and 15.
자동차용 발전기(1)로부터의 3상 전압은 한 정류기(3)에 의하여 반파 정류된다. 이 반파 정류된 3상 전압은 변압기(16)를 통하여 소정 크기의 단상 전압으로 변환된다. 변압기(16)로부터의 단상 교류 전압은, 정류기(5)를 통하여 직류 전압의 형태로 제1 부하(15)에 인가된다. 제1 부하(15)의 특성상 전압 조정부가 마련되지 않고 있다.The three-phase voltage from the motor generator 1 is half-wave rectified by one rectifier 3. This half-wave rectified three-phase voltage is converted into a single-phase voltage of a predetermined magnitude through the transformer 16. The single phase AC voltage from the transformer 16 is applied to the first load 15 in the form of a DC voltage through the rectifier 5. Due to the characteristics of the first load 15, the voltage adjusting unit is not provided.
자동차용 발전기(1)로부터의 3상 전압은, 정류기들(2, 3)을 통하여 전파 정류되어 직류 전압으로 변환된다. 이 직류 전압은 충전기(6)에 충전됨과 동시에 제2 부하(13)에 인가된다. 전압 조정부(8), 여자 코일(9) 및 다이오드(91)는 제2 부하(13)에 인가된 전압을 안정되게 조정한다. 여자 코일(9)에 흐르는 전류는 트랜지스터(82)의 동작 상태에 따라 결정된다.The three-phase voltage from the automotive generator 1 is full-wave rectified through the rectifiers 2 and 3 and converted into a direct current voltage. This DC voltage is charged to the charger 6 and applied to the second load 13 at the same time. The voltage adjusting unit 8, the exciting coil 9, and the diode 91 stably adjust the voltage applied to the second load 13. The current flowing in the exciting coil 9 is determined in accordance with the operating state of the transistor 82.
제2 부하(13)에 인가된 전압이 상대적으로 높으면, 연산 증폭기(81)의 출력 전압이 높아진다. 이에 따라, 트랜지스터(82)의 컬렉터 전류가 증대되므로, 상대적으로 적은 전류가 다이오드(91)를 통하여 제2 부하(13)로 흐른다. 즉, 제2 부하(13)에 추가 인가되는 전압이 상대적으로 낮아지므로, 제2 부하(13)에 인가되는 전압이 안정된다.When the voltage applied to the second load 13 is relatively high, the output voltage of the operational amplifier 81 becomes high. As a result, the collector current of the transistor 82 increases, so that a relatively small current flows through the diode 91 to the second load 13. That is, since the voltage additionally applied to the second load 13 becomes relatively low, the voltage applied to the second load 13 is stabilized.
제2 부하(13)에 인가된 전압이 상대적으로 낮으면, 연산 증폭기(81)의 출력 전압이 낮아진다. 이에 따라, 트랜지스터(82)의 컬렉터 전류가 감소되므로, 상대적으로 큰 전류가 다이오드(91)를 통하여 제2 부하(13)로 흐른다. 즉, 제2 부하(13)에 추가 인가되는 전압이 상대적으로 높아지므로, 제2 부하(13)에 인가되는 전압이 안정된다.When the voltage applied to the second load 13 is relatively low, the output voltage of the operational amplifier 81 is lowered. As a result, the collector current of the transistor 82 is reduced, so that a relatively large current flows through the diode 91 to the second load 13. That is, since the voltage additionally applied to the second load 13 becomes relatively high, the voltage applied to the second load 13 is stabilized.
자동차용 발전기(1)로부터 정류기(3)에 의하여 반파 정류된 3상 전압은, 위상 제어 정류기(4) 예를 들어, SCR(Sillicon Controlled Rectifier)을 통하여 직류 전압으로 변환된다. 이 직류 전압은 다이오드(11) 및 인덕터(12)에 의하여 정형되어, 제3 부하(14)에 인가됨과 동시에 충전기(7)에 충전된다. 제어기(10)는 제3 부하(14)에 인가되는 전압의 크기에 반비례한 시간 동안 위상 제어 정류기(4)를 동작시키므로, 안정된 직류 전압을 제3 부하(14)에 인가할 수 있다.The three-phase voltage half-wave rectified by the rectifier 3 from the automobile generator 1 is converted into a direct current voltage via the phase controlled rectifier 4, for example, a SCR (Sillicon Controlled Rectifier). This DC voltage is shaped by the diode 11 and the inductor 12, and is applied to the third load 14 and charged in the charger 7 at the same time. Since the controller 10 operates the phase controlled rectifier 4 for a time inversely proportional to the magnitude of the voltage applied to the third load 14, the controller 10 may apply a stable DC voltage to the third load 14.
이상 설명된 바와 같이, 본 발명에 따른 자동차용 전원 공급 방법에 의하면, 한 자동차용 발전기로부터 개별적이고 독립적인 전원들을 생성하여 공급할 수 있으므로, 발전기를 보다 효율적으로 사용할 수 있다.As described above, according to the automotive power supply method according to the present invention, since it is possible to generate and supply individual and independent power sources from one automobile generator, it is possible to use the generator more efficiently.
본 발명은 상기 실시예에 한정되지 않고, 당업자의 수준에서 그 변형 및 개량이 가능하다.The present invention is not limited to the above embodiments, and modifications and improvements are possible at the level of those skilled in the art.
