輸入(ru)(ru)(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)通(tong)過(guo)保險(xian)絲 1、干(gan)擾(rao)控制濾波器(qi)(qi)(qi) 2 和整(zheng)流(liu)(liu)(liu)器(qi)(qi)(qi) 3 到(dao)達初級(ji)開(kai)(kai)關系(xi)統。濾波器(qi)(qi)(qi)可(ke)(ke)降低(di)反饋(kui)到(dao)供(gong)電(dian)(dian)(dian)(dian)系(xi)統的(de)(de)干(gan)擾(rao)電(dian)(dian)(dian)(dian)壓(ya)，NTC 電(dian)(dian)(dian)(dian)阻器(qi)(qi)(qi) 22 可(ke)(ke)限制浪涌(yong)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。回饋(kui)整(zheng)流(liu)(liu)(liu)輸入(ru)(ru)(ru)(ru)可(ke)(ke)用于連(lian)接額外的(de)(de)存儲卡。230 伏(fu)輸入(ru)(ru)(ru)(ru)通(tong)過(guo)整(zheng)流(liu)(liu)(liu)器(qi)(qi)(qi)直接為電(dian)(dian)(dian)(dian)容器(qi)(qi)(qi) 4 充滿電(dian)(dian)(dian)(dian)，而 115 伏(fu)輸入(ru)(ru)(ru)(ru)則介入(ru)(ru)(ru)(ru)電(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)組合(he) 4a/4b。與整(zheng)流(liu)(liu)(liu)器(qi)(qi)(qi)配(pei)合(he)，這就(jiu)(jiu)是電(dian)(dian)(dian)(dian)壓(ya)倍(bei)增器(qi)(qi)(qi)。轉換器(qi)(qi)(qi)在(zai) "半橋(qiao)電(dian)(dian)(dian)(dian)路(lu)(lu) "中作為推挽式轉換器(qi)(qi)(qi)運(yun)行(xing)。開(kai)(kai)關晶體管 6a 和 6b 由控制電(dian)(dian)(dian)(dian)路(lu)(lu) 8 以(yi)可(ke)(ke)變的(de)(de)脈沖寬度(du)周期性地接通(tong)和斷開(kai)(kai)。輸入(ru)(ru)(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)以(yi)交替極性出現在(zai)變壓(ya)器(qi)(qi)(qi) 5 的(de)(de)初級(ji)繞(rao)組上，分(fen)流(liu)(liu)(liu)器(qi)(qi)(qi) 7 為電(dian)(dian)(dian)(dian)子限流(liu)(liu)(liu)提(ti)供(gong)信(xin)號，以(yi)保護半導體免受(shou)過(guo)載。電(dian)(dian)(dian)(dian)路(lu)(lu) 10 監控輸入(ru)(ru)(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)。當達到(dao)規定(ding)的(de)(de)限值時，開(kai)(kai)關晶體管 6a 和 6b 將被禁用。一旦輸入(ru)(ru)(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)回到(dao)容差范圍內，系(xi)統就(jiu)(jiu)會(hui)自動(dong)恢復正常(chang)運(yun)行(xing)。
