電(dian)(dian)鍍(du)屬(shu)于電(dian)(dian)解(jie)加工過(guo)程，電(dian)(dian)源(yuan)的因素必將對電(dian)(dian)鍍(du)工藝(yi)過(guo)程產生直接影響(xiang)，在(zai)電(dian)(dian)鍍(du)工藝(yi)中具有重(zhong)要地位。電(dian)(dian)鍍(du)電(dian)(dian)源(yuan)和低紋波(bo)系數整(zheng)流(liu)電(dian)(dian)源(yuan)在(zai)電(dian)(dian)鍍(du)行(xing)業中的應用(yong)，讓電(dian)(dian)鍍(du)界同仁在(zai)選擇整(zheng)流(liu)電(dian)(dian)源(yuan)、解(jie)決電(dian)(dian)鍍(du)故(gu)障(zhang)、提高電(dian)(dian)鍍(du)質量(liang)有所幫助(zhu)。

1、整流器的基本類型

硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)器(qi)：硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)器(qi)使(shi)用(yong)歷史長，技術成(cheng)(cheng)熟，目(mu)前是整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)器(qi)主流(liu)(liu)(liu)(liu)(liu)(liu)(liu)產品(pin)。各(ge)種(zhong)(zhong)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電路(lu)獲得的(de)(de)均(jun)是脈動(dong)直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電，不是純直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)。為(wei)了比較脈動(dong)成(cheng)(cheng)份的(de)(de)多少，一般用(yong)紋(wen)波(bo)(bo)(bo)(bo)系數(shu)來表示，其數(shu)值越小，交流(liu)(liu)(liu)(liu)(liu)(liu)(liu)成(cheng)(cheng)份越少，越接(jie)近純直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)。各(ge)種(zhong)(zhong)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電路(lu)的(de)(de)波(bo)(bo)(bo)(bo)動(dong)系數(shu)不同。其由大(da)到(dao)小的(de)(de)次序為(wei)：三相(xiang)半波(bo)(bo)(bo)(bo)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)、三相(xiang)全(quan)波(bo)(bo)(bo)(bo)橋式整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)或(huo)帶平衡電抗器(qi)的(de)(de)六相(xiang)雙(shuang)反星形整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)。可(ke)控(kong)(kong)硅(gui)利(li)用(yong)改變可(ke)控(kong)(kong)硅(gui)管(guan)導通(tong)(tong)角(jiao)(jiao)來調整(zheng)(zheng)(zheng)輸出平均(jun)直(zhi)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)大(da)小的(de)(de)普通(tong)(tong)可(ke)控(kong)(kong)硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)器(qi)，可(ke)控(kong)(kong)硅(gui)管(guan)輸出的(de)(de)是間(jian)斷脈沖波(bo)(bo)(bo)(bo)，其紋(wen)波(bo)(bo)(bo)(bo)系數(shu)的(de)(de)受導通(tong)(tong)角(jiao)(jiao)控(kong)(kong)制(zhi)，輸出紋(wen)波(bo)(bo)(bo)(bo)系數(shu)大(da)于(yu)普通(tong)(tong)硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)(liu)(liu)(liu)電路(lu)。

2、開關電源

開(kai)關電(dian)(dian)源(yuan)兼有硅整(zheng)流(liu)器的(de)波形平滑性優點(dian)(dian)及(ji)可控硅整(zheng)流(liu)器的(de)調壓(ya)方(fang)便的(de)優點(dian)(dian)，電(dian)(dian)流(liu)效率(lv)高體積最(zui)小(xiao)，數千安培(pei)至(zhi)上萬安培(pei)的(de)大功率(lv)開(kai)關電(dian)(dian)源(yuan)已(yi)進入(ru)生(sheng)產實用階(jie)段。開(kai)關電(dian)(dian)源(yuan)其頻(pin)(pin)率(lv)已(yi)達音頻(pin)(pin)，通過濾波實現(xian)(xian)低紋波輸出更為簡(jian)便易行(xing)。而且穩流(liu)、穩壓(ya)等功能更易實現(xian)(xian)。因此，開(kai)關電(dian)(dian)源(yuan)是今后發展的(de)方(fang)向(xiang)。

3、設備

脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)主要(yao)是由嵌入式(shi)單片計算機(ji)等進(jin)行控(kong)制(zhi)，因此，除實現脈(mo)(mo)沖(chong)(chong)(chong)輸(shu)(shu)出(chu)(chu)之外(wai)，一(yi)(yi)般具備(bei)多種控(kong)制(zhi)功能(neng)。（1)自(zi)動(dong)(dong)(dong)穩流穩壓(ya)。傳統硅整(zheng)流器電(dian)(dian)(dian)流或電(dian)(dian)(dian)壓(ya)無法(fa)自(zi)動(dong)(dong)(dong)穩定，隨電(dian)(dian)(dian)網電(dian)(dian)(dian)壓(ya)的(de)(de)波(bo)動(dong)(dong)(dong)而(er)(er)波(bo)動(dong)(dong)(dong)。而(er)(er)脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)則擁有(you)(you)高(gao)精度的(de)(de)自(zi)動(dong)(dong)(dong)調節(jie)(jie)功能(neng)，脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)輸(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)可(ke)(ke)以幾乎不變。脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)自(zi)動(dong)(dong)(dong)調節(jie)(jie)功能(neng)一(yi)(yi)般具有(you)(you)二種模式(shi)：一(yi)(yi)，恒(heng)電(dian)(dian)(dian)流限(xian)壓(ya)模式(shi)。二，恒(heng)電(dian)(dian)(dian)壓(ya)限(xian)流模式(shi)。（2)多段(duan)(duan)式(shi)運(yun)行模式(shi)。鋁陽極氧化(hua)或硬鉻(ge)電(dian)(dian)(dian)鍍(du)時(shi)，往往需要(yao)進(jin)行反向(xiang)(xiang)電(dian)(dian)(dian)解、大(da)電(dian)(dian)(dian)流沖(chong)(chong)(chong)擊、階梯送電(dian)(dian)(dian)等操作。具有(you)(you)多段(duan)(duan)式(shi)運(yun)行模式(shi)的(de)(de)脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)則只需提前(qian)設(she)定，生產時(shi)可(ke)(ke)自(zi)動(dong)(dong)(dong)按(an)順(shun)序進(jin)行自(zi)動(dong)(dong)(dong)調節(jie)(jie)。這一(yi)(yi)功能(neng)對硬鉻(ge)電(dian)(dian)(dian)鍍(du)是非常(chang)有(you)(you)用(yong)(yong)的(de)(de)，每一(yi)(yi)段(duan)(duan)時(shi)間可(ke)(ke)在(zai)0～255秒內(nei)調節(jie)(jie)設(she)定。（3)雙向(xiang)(xiang)脈(mo)(mo)沖(chong)(chong)(chong)功能(neng)。正負脈(mo)(mo)沖(chong)(chong)(chong)頻率、占空比、正反向(xiang)(xiang)輸(shu)(shu)出(chu)(chu)時(shi)間均可(ke)(ke)獨立調節(jie)(jie)，使用(yong)(yong)靈(ling)活(huo)、方便。配合硬鉻(ge)電(dian)(dian)(dian)鍍(du)工藝，可(ke)(ke)獲得不同(tong)(tong)物理性(xing)能(neng)的(de)(de)鍍(du)層。（4)直流疊加(jia)功能(neng)。輸(shu)(shu)出(chu)(chu)正反向(xiang)(xiang)脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)流的(de)(de)同(tong)(tong)時(shi)，由同(tong)(tong)一(yi)(yi)臺電(dian)(dian)(dian)源(yuan)(yuan)疊加(jia)輸(shu)(shu)出(chu)(chu)一(yi)(yi)純直流成分，更拓寬了脈(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)使用(yong)(yong)范圍及用(yong)(yong)途。
