很多新手工(gong)程師對于高壓放(fang)大器和高壓電源等都無法分清，下面就來為大家詳細介紹(shao)。

　　高(gao)壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)：高(gao)壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)又稱(cheng)直流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)，它是(shi)由(you)交(jiao)流(liu)(liu)(liu)市(shi)電(dian)(dian)(dian)(dian)或(huo)三(san)相電(dian)(dian)(dian)(dian)輸入，數千(qian)伏以上(shang)或(huo)數萬伏以上(shang)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)輸出的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)，輸出功(gong)率數百瓦至數千(qian)瓦，一般可穩(wen)(wen)壓(ya)(ya)或(huo)穩(wen)(wen)流(liu)(liu)(liu)。早先的(de)(de)直流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)是(shi)將交(jiao)流(liu)(liu)(liu)市(shi)電(dian)(dian)(dian)(dian)或(huo)三(san)相電(dian)(dian)(dian)(dian)由(you)工頻(pin)高(gao)壓(ya)(ya)變壓(ya)(ya)器升壓(ya)(ya)變成交(jiao)流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)，然后整流(liu)(liu)(liu)濾波(bo)得到直流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)。由(you)于頻(pin)率低(di)，電(dian)(dian)(dian)(dian)源(yuan)的(de)(de)體積(ji)和重量都比較大(da)，轉換(huan)效(xiao)率和穩(wen)(wen)定(ding)度差(cha)。隨(sui)著(zhu)開關電(dian)(dian)(dian)(dian)源(yuan)技術的(de)(de)發展與成熟(shu)，采用(yong)高(gao)頻(pin)開關變換(huan)技術結合高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)的(de)(de)特(te)點而研(yan)制的(de)(de)直流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)成為主流(liu)(liu)(liu)，這種(zhong)電(dian)(dian)(dian)(dian)源(yuan)又稱(cheng)為“高(gao)頻(pin)高(gao)壓(ya)(ya)直流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)”。其(qi)特(te)點是(shi)工作頻(pin)率高(gao)、體積(ji)小、重量輕、功(gong)率大(da)、效(xiao)率高(gao)、紋波(bo)小、儲(chu)能低(di)和高(gao)穩(wen)(wen)定(ding)度、高(gao)可靠性。為了滿足不(bu)同使用(yong)的(de)(de)要求(qiu)，有些直流(liu)(liu)(liu)高(gao)壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)制成穩(wen)(wen)壓(ya)(ya)穩(wen)(wen)流(liu)(liu)(liu)自(zi)動轉換(huan)的(de)(de)形式，

　　高(gao)(gao)壓(ya)(ya)放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)：高(gao)(gao)壓(ya)(ya)放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)是一種高(gao)(gao)電壓(ya)(ya)幅度輸出的(de)信號(hao)(hao)(hao)放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)，幅度一般可(ke)達(da)數千伏以上，響(xiang)應帶寬可(ke)達(da)20KHz，上升速率可(ke)達(da)100～1000V/μS，失真度＜1%，分(fen)單(dan)極和雙極放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)。單(dan)極放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)只(zhi)能放(fang)(fang)大(da)(da)(da)單(dan)極性(xing)直(zhi)流(liu)或單(dan)極性(xing)脈沖和其他單(dan)極性(xing)信號(hao)(hao)(hao)。雙極放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)可(ke)以放(fang)(fang)大(da)(da)(da)交流(liu)信號(hao)(hao)(hao)直(zhi)流(liu)信號(hao)(hao)(hao)或其他任何信號(hao)(hao)(hao)，稱為任意(yi)波形(xing)高(gao)(gao)壓(ya)(ya)放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)。也可(ke)以做成(cheng)功能集(ji)成(cheng)化的(de)高(gao)(gao)壓(ya)(ya)放(fang)(fang)大(da)(da)(da)器(qi)(qi)(qi)(qi)(qi)模塊，以便(bian)多路(lu)組(zu)合應用。
