本地/遠地檢測

        選(xuan)用本地(di)檢測，電(dian)(dian)源(yuan)的(de)(de)(de)反(fan)饋(kui)取自(zi)輸出連接器上(shang)的(de)(de)(de)輸出端子(zi)，這種方法忽略了負(fu)(fu)(fu)(fu)載(zai)線壓(ya)降的(de)(de)(de)損失，限(xian)制了電(dian)(dian)源(yuan)的(de)(de)(de)調整能(neng)力，負(fu)(fu)(fu)(fu)載(zai)引線越(yue)長、電(dian)(dian)阻越(yue)大，終(zhong)端負(fu)(fu)(fu)(fu)載(zai)調整能(neng)力就越(yue)差，適(shi)用于對負(fu)(fu)(fu)(fu)載(zai)調整率要求(qiu)不(bu)高的(de)(de)(de)場合(he)。選(xuan)用遠(yuan)地(di)檢測，電(dian)(dian)源(yuan)的(de)(de)(de)反(fan)饋(kui)直接取自(zi)負(fu)(fu)(fu)(fu)載(zai)，電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)的(de)(de)(de)輸出自(zi)動補償負(fu)(fu)(fu)(fu)載(zai)引線的(de)(de)(de)影(ying)響，使負(fu)(fu)(fu)(fu)載(zai)上(shang)的(de)(de)(de)電(dian)(dian)壓(ya)保持不(bu)變(bian)。

說(shuo)明：

1）選用遠地檢測時，如果負載(zai)電壓為額(e)定值，模塊實際輸出(chu)(chu)(chu)電壓可(ke)能會超出(chu)(chu)(chu)其最大(da)輸出(chu)(chu)(chu)范圍，從(cong)而導(dao)致保護電路動(dong)作或者出(chu)(chu)(chu)現輸出(chu)(chu)(chu)失調狀態。

2）選用(yong)遠(yuan)地檢(jian)(jian)測(ce)(ce)(ce)時，通過檢(jian)(jian)測(ce)(ce)(ce)線(xian)在模(mo)塊輸出上拾取的(de)(de)(de)噪聲(sheng)將影(ying)響負載調整率(lv)。為盡量(liang)減小噪聲(sheng)影(ying)響，應使用(yong)屏(ping)蔽雙絞線(xian)將電(dian)源的(de)(de)(de)檢(jian)(jian)測(ce)(ce)(ce)線(xian)接(jie)到負載的(de)(de)(de)電(dian)壓檢(jian)(jian)測(ce)(ce)(ce)端，屏(ping)蔽層(ceng)(ceng)的(de)(de)(de)一端接(jie)至(zhi)電(dian)源輸出連接(jie)器的(de)(de)(de)接(jie)地端子上，另一端懸空。(不要使用(yong)屏(ping)蔽層(ceng)(ceng)作(zuo)為檢(jian)(jian)測(ce)(ce)(ce)線(xian)！)

并聯輸出

串聯輸出

        采用兩臺(tai)或(huo)多臺(tai)模塊串(chuan)聯可拓(tuo)展電壓輸出范圍。但(dan)應注意負(fu)載電流不應超(chao)過每臺(tai)模塊電流輸出范圍。

典(dian)型應用

航(hang)空航(hang)天DC/DC模塊研發、測試

        衛星電(dian)(dian)(dian)(dian)源系(xi)(xi)統(tong)中(zhong)(zhong)的DC-DC模塊是負責將輸出的直(zhi)流(liu)母線(xian)電(dian)(dian)(dian)(dian)壓轉(zhuan)換成其(qi)他等級(ji)的直(zhi)流(liu)電(dian)(dian)(dian)(dian)壓，以(yi)滿(man)足(zu)不(bu)同設(she)備的用電(dian)(dian)(dian)(dian)需求(qiu)。目前(qian)，DC/DC變(bian)換器在衛星等航(hang)天(tian)工程項目電(dian)(dian)(dian)(dian)源系(xi)(xi)統(tong)設(she)計中(zhong)(zhong)的使(shi)用已經非常普遍，其(qi)可以(yi)不(bu)受(shou)輸入電(dian)(dian)(dian)(dian)壓和負載波動的影響(xiang)而提供穩定的輸出電(dian)(dian)(dian)(dian)壓。同時(shi)，DC/DC變(bian)換器在變(bian)換過(guo)程中(zhong)(zhong)使(shi)用了變(bian)壓器進行電(dian)(dian)(dian)(dian)隔離，可以(yi)保護整個系(xi)(xi)統(tong)免受(shou)隔離故(gu)障的影響(xiang)。

        DC/DC變換器以(yi)其體積(ji)小巧(qiao)、性能、使用(yong)方便等(deng)顯著特點，在通信(xin)、網絡和(he)航(hang)(hang)(hang)空航(hang)(hang)(hang)天等(deng)軍民用(yong)領(ling)域得到(dao)日益廣泛的應用(yong)。在航(hang)(hang)(hang)空航(hang)(hang)(hang)天等(deng)junyong高(gao)科(ke)技領域的(de)(de)科(ke)研和生產過程中(zhong)，DC/DC變(bian)換器為(wei)各部分(fen)電(dian)(dian)子線路(lu)的(de)(de)正(zheng)常(chang)運行(xing)提(ti)供(gong)供(gong)電(dian)(dian)電(dian)(dian)源，其質(zhi)量穩定性影響到整個系統(tong)的(de)(de)可靠性，必須采用高(gao)精(jing)密的(de)(de)測(ce)試(shi)設(she)備，對DC/DC變(bian)換器進(jin)行(xing)測(ce)試(shi)，才能保(bao)證系統(tong)對電(dian)(dian)源的(de)(de)高(gao)可靠性要求。

        為了(le)保(bao)(bao)障(zhang)飛船在(zai)軌飛行(xing)電(dian)(dian)力正常(chang)，在(zai)衛星(xing)通信的地面研究、測試(shi)(shi)和試(shi)(shi)驗(yan)中提供(gong)(gong)(gong)程(cheng)控模擬電(dian)(dian)源，對衛星(xing)以及相應通信設備(bei)進行(xing)不同供(gong)(gong)(gong)電(dian)(dian)狀(zhuang)(zhuang)態進行(xing)模擬，從而測試(shi)(shi)出設備(bei)在(zai)供(gong)(gong)(gong)電(dian)(dian)或異常(chang)乃至各種供(gong)(gong)(gong)電(dian)(dian)狀(zhuang)(zhuang)態下(xia)的通信工作情(qing)況(kuang)，確(que)保(bao)(bao)衛星(xing)通信在(zai)各種工作狀(zhuang)(zhuang)態下(xia)的正常(chang)運行(xing)。衛星(xing)的通信是(shi)極其(qi)復雜且難(nan)以預(yu)料的，尤其(qi)是(shi)在(zai)供(gong)(gong)(gong)電(dian)(dian)發(fa)生變化或異常(chang)的情(qing)況(kuang)下(xia)更需(xu)保(bao)(bao)障(zhang)可(ke)靠(kao)性，衛星(xing)的可(ke)靠(kao)運行(xing)也在(zai)很大(da)程(cheng)度上取決于其(qi)供(gong)(gong)(gong)電(dian)(dian)的可(ke)靠(kao)性，只有(you)模擬供(gong)(gong)(gong)電(dian)(dian)試(shi)(shi)驗(yan)的更加完備(bei)才能保(bao)(bao)證(zheng)其(qi)可(ke)靠(kao)性。

用(yong)于微波電子、daodan導航等產品的(de)研發及測(ce)試

        微(wei)波器(qi)件(jian)包括微(wei)波振蕩(dang)器(qi)、功率放大(da)器(qi)、混頻器(qi)、檢(jian)波器(qi)等(deng)，通過電路設計，利用(yong)(yong)這些器(qi)件(jian)可(ke)組裝(zhuang)成(cheng)發射機、天線系統(tong)等(deng)，用(yong)(yong)于雷達、電子戰(zhan)系統(tong)和通訊系統(tong)等(deng)電子裝(zhuang)備(bei)。

        在微波電子設備(bei)及(ji)器件(jian)的(de)研發設計、真空電子設備(bei)等junyong設備的研發設計(ji)中，為了保障junyong設備供(gong)電(dian)正常，對其供(gong)電(dian)電(dian)源的測(ce)試(shi)和(he)試(shi)驗(yan)是(shi)十分(fen)重要的，以(yi)確保其在各種工作狀(zhuang)態下(xia)的供(gong)電(dian)正常運行。因而(er)需(xu)要程控(kong)直流電(dian)源類高端精密儀器進行科學有效的試(shi)驗(yan)和(he)測(ce)試(shi)。

        對(dui)daodan導航通(tong)(tong)(tong)信設(she)備(bei)、空(kong)間防御通(tong)(tong)(tong)信裝備(bei)進行不(bu)同(tong)供(gong)(gong)電狀(zhuang)(zhuang)態(tai)模擬，從而測試出設(she)備(bei)在供(gong)(gong)電或異常(chang)乃至各種(zhong)供(gong)(gong)電狀(zhuang)(zhuang)態(tai)下的(de)通(tong)(tong)(tong)信工作情況，確(que)保(bao)其(qi)通(tong)(tong)(tong)信在各種(zhong)工作狀(zhuang)(zhuang)態(tai)下正常(chang)運行。daodan導航通信、空間防御通信等是極其(qi)復雜且(qie)難(nan)以預料的，尤(you)其(qi)是在供電發(fa)生(sheng)變化或異常(chang)的情(qing)況(kuang)下(xia)更(geng)需保(bao)障(zhang)可靠性。使(shi)用1764程控直(zhi)流電源，就能輕松(song)應對這一挑(tiao)戰。
