1、整流器的基本類型

硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi)：硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi)使用歷(li)史長，技術成熟，目前是整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi)主流(liu)(liu)(liu)(liu)產品(pin)。各(ge)(ge)種整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)電(dian)路(lu)獲(huo)得的均(jun)是脈(mo)動直(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)，不是純(chun)直(zhi)(zhi)流(liu)(liu)(liu)(liu)。為了(le)比較脈(mo)動成份的多少，一(yi)般用紋(wen)波(bo)(bo)(bo)(bo)系數來表示，其數值(zhi)越小，交流(liu)(liu)(liu)(liu)成份越少，越接近(jin)純(chun)直(zhi)(zhi)流(liu)(liu)(liu)(liu)。各(ge)(ge)種整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)電(dian)路(lu)的波(bo)(bo)(bo)(bo)動系數不同。其由(you)大(da)到小的次序為：三相半(ban)波(bo)(bo)(bo)(bo)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)、三相全(quan)波(bo)(bo)(bo)(bo)橋式整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)或帶平(ping)衡電(dian)抗(kang)器(qi)的六(liu)相雙反星形(xing)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)。可控(kong)硅(gui)利用改(gai)變(bian)可控(kong)硅(gui)管(guan)導通(tong)角來調整(zheng)(zheng)(zheng)輸出(chu)平(ping)均(jun)直(zhi)(zhi)流(liu)(liu)(liu)(liu)大(da)小的普通(tong)可控(kong)硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)器(qi)，可控(kong)硅(gui)管(guan)輸出(chu)的是間(jian)斷脈(mo)沖波(bo)(bo)(bo)(bo)，其紋(wen)波(bo)(bo)(bo)(bo)系數的受導通(tong)角控(kong)制，輸出(chu)紋(wen)波(bo)(bo)(bo)(bo)系數大(da)于普通(tong)硅(gui)整(zheng)(zheng)(zheng)流(liu)(liu)(liu)(liu)電(dian)路(lu)。

2、開關電源
