본 고안은 컴퓨터, OA 기기에서 직류(DC)전원을 공급하는 회로에 관한 것으로 특히, 전원공급장치(SMPS)가 단일 DC전압을 출력하는 경우 출력 DC전압을 프로그래머블하게 가변시켜 다양한 레벨의 DC전원을 공급할 수 있도록 한 DC/DC 변환장치에 관한 것이다.The present invention relates to a circuit for supplying direct current (DC) power in computers and OA devices. In particular, when the power supply unit (SMPS) outputs a single DC voltage, the output DC voltage is programmable to vary the level of DC power. It relates to a DC / DC converter that can be supplied.
종래의 DC/DC 변환기는 입력 DC전원을 단일 레벨의 DC전원으로만 변환시켜 공급하며 다양한 DC전원의 공급이 불가능하다.Conventional DC / DC converters convert and supply an input DC power source to a single level DC power source and cannot supply various DC power sources.
예를들어 SMPS의 출력전압이 9V인 경우 OA 기기의 각 회로블록에서 요구되는 DC전원이 12V, 16V이면 9V/12V변환기와 9V/16V 변환기를 각각 구비해야 한다.For example, if the output voltage of SMPS is 9V, if the DC power required for each circuit block of OA equipment is 12V and 16V, 9V / 12V converter and 9V / 16V converter should be provided respectively.
따라서 회로블록별로 다양한 레벨의 DC전원이 요구되는 경우에는 다수의 DC/DC 변환기를 구비해야 되고 다양한 전원공급을 위한 SMPS 장치의 재설계로 인하여 전원장치의 가격 상승이 초래되는 문제점이 있었다.Accordingly, when various levels of DC power are required for each circuit block, a plurality of DC / DC converters must be provided, and the price of the power supply device is increased due to the redesign of the SMPS device for various power supplies.
본 고안은 이와같은 종래의 문제점을 해결하기 위하여 DC 전압레벨의 가변을 위한 승압수단을 구비하고 승압수단의 DC 승압레벨을 임의로 선택하는 스위칭 수단을 구비하여 단일 DC 입력을 다양한 레벨의 DC전압으로 가변시켜 공급 가능하게 하므로서 회로구성의 간소화 및 원가절감을 기할 수 있도록 하는데 그 목적이 있는 것으로, 첨부된 도면에 의하여 본 고안의 구성을 설명한다.The present invention includes a boosting means for varying the DC voltage level and a switching means for arbitrarily selecting the DC boosting level of the boosting means to solve the conventional problems, such that a single DC input is changed to a DC voltage of various levels. The purpose of the present invention is to provide a simplified circuit configuration and reduce costs by enabling the supply of the present invention.
본 고안 DC/DC 변환장치는 제 1 도에서와 같이, 단일 DC입력전압을 다수의 DC레벨로 승압시켜 출력하는 승압수단(1)과, 상기 승압수단(1)의 출력 DC레벨을 결정하는 전압설정부(2)와, 상기 전압설정부(2)의 선택제어를 위하여 설정용 저항(Ra,Rb,Rc,Rx)을 상기 승압수단(1)에 연결 또는 차단시키는 전압선택 제어수단(3)과, 상기 승압수단(1)의 출력 DC 전원에서 노이즈를 제거하고 부하측으로부터의 역전류 유입을 방지하는 출력보정부(4)로 구성된 것으로 미설명 부호 R0는 저항, OPa, OPb, OPc는 광결합기, CO는 콘덴서, DO는 다이오드, IC1는 승압용 집적회로이다.The DC / DC converter according to the present invention has a voltage booster (1) for boosting and outputting a single DC input voltage to a plurality of DC levels as shown in FIG. 1, and a voltage for determining an output DC level of the booster (1). Voltage selection control means (3) for connecting or disconnecting the setting resistors (Ra, Rb, Rc, Rx) to the boosting means (1) for setting control of the setting section (2) and the voltage setting section (2). And an output compensator 4 which removes noise from the output DC power supply of the boosting means 1 and prevents reverse current from flowing from the load side. Reference numeral R0 denotes a resistor, OPa, OPb, and OPc an optical coupler. , CO is a capacitor, DO is a diode, and IC1 is a boost circuit.
이와같이 구성된 본 고안의 작용효과는 제 1 도에서와 같이, 승압수단(1)에 구비되는 집적회로(IC1)에 의한 출력단(OUT)전압은 입력 DC전압(VF)에 대하여 Vout=VF×R×/(Ra+Rb+Rc)[V]로 결정되므로 각 회로불록에서 요구되는 DC 전압 레벨에 따라 통상의 SMPS 제어장치에서 소정의 제어신호(Pa, Pb, Pc)중에서 임의의 신호를 하이 또는 로우로 공급하게 된다.As shown in FIG. 1, the output terminal OUT voltage by the integrated circuit IC1 included in the boosting means 1 is Vout = VF x R x with respect to the input DC voltage VF. / (Ra + Rb + Rc) [V], so any signal among the predetermined control signals Pa, Pb, and Pc is high or low in a normal SMPS controller according to the DC voltage level required in each circuit block. To be supplied.
예를들어 제어신호(Pa)가 하이이고 제어신호(Pb, Pc)가 로우이면 광결합기(OPa)는 오프되어 저항(Ra)이 오픈되는 한편 광결합기(OPb, OPc)는 온되어 저항(Rb, Rc)이 저항(Rx)과 연결되므로 승압수단(1)에 의하여 승압되어 출력되는 Vout=VF×R×/(Rb+Rc)[V]가 된다.For example, when the control signal Pa is high and the control signals Pb and Pc are low, the optocoupler OPa is turned off to open the resistor Ra, while the optocouplers OPb and OPc are turned on and the resistor Rb. , Rc is connected to the resistor Rx, so that Vout = VF x Rx / (Rb + Rc) [V] which is boosted and output by the boosting means 1.
즉, 제어신호(Pa, Pb, Pc)에 의하여 전압선택 스위칭 수단(3)이 온 또는 오프됨에 따라 전압설정부(2)에 의한 전압설정치가 결정되고 이 값에 의하여 승압수단(1)에 의한 DC승압비율이 가변됨에 따라 출력되는 DC전압값이 다양한 값으로 가변 제어되는 것이다.That is, as the voltage selection switching means 3 is turned on or off by the control signals Pa, Pb, and Pc, the voltage setting value by the voltage setting unit 2 is determined, and the boosting means 1 As the DC boost ratio is variable, the output DC voltage value is variably controlled to various values.
이와같이 승압되어 출력되는 DC전원은 콘덴서(CO)에 의하여 리플 및 노이즈가 제거되어 다이오드(D0)를 통해 출력되며 때대 출력단으로부터의 역전류는 다이오드(D0)의 역방향 전류 특성에 의하여 저지된다.In this way, the DC power boosted and output is output through the diode D0 with ripple and noise removed by the capacitor CO, and the reverse current from the output stage is blocked by the reverse current characteristic of the diode D0.
이상에서 설명한 바와같이 본 고안에 의하면 단일 DC 입력전원을 다양한 레벨의 DC출력 전원으로 변환할 수 있으므로 디지탈 B/D내에서 필요한 소전력 DC전압을 용이하게 공급할 수 있고 SMPS가 단일 DC전압 출력으로 설계 가능하므로 전원 회로구성의 간소화 및 이를 통한 원가절감과 조립작업성 향상을 기할 수 있는 효과가 있다.As described above, according to the present invention, since a single DC input power can be converted into various levels of DC output power, it is possible to easily supply a small power DC voltage required in digital B / D, and SMPS is designed as a single DC voltage output. Therefore, it is possible to simplify the circuit configuration of the power supply, thereby reducing the cost and improving the assembly workability.
