計算機電源是一種安裝在主機箱(xiang)內(nei)的封(feng)閉式*立部件，
它的(de)(de)作用(yong)是將交流電(dian)(dian)(dian)(dian)(dian)通過一(yi)個(ge)(ge)(ge)(ge)開(kai)關電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)變(bian)壓(ya)器換為(wei)(wei)5V，-5V，+12V，-12V，+3.3V等穩(wen)定的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)(dian)，以(yi)(yi)供(gong)(gong)(gong)應(ying)(ying)主機(ji)箱內系統(tong)版，軟盤(pan)(pan)，硬(ying)(ying)盤(pan)(pan)驅動及各(ge)種適配器擴展卡等系統(tong)部件(jian)使用(yong)。通俗來(lai)講就是，一(yi)個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)壞了，另一(yi)個(ge)(ge)(ge)(ge)備(bei)份電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)代(dai)替(ti)其(qi)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。可(ke)以(yi)(yi)通過為(wei)(wei)節(jie)點(dian)和(he)磁(ci)(ci)盤(pan)(pan)提(ti)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)池后援來(lai)增(zeng)強硬(ying)(ying)件(jian)的(de)(de)可(ke)用(yong)性(xing)。HP 支持的(de)(de)不間斷電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)（UPS），如(ru) HP PowerTrust，可(ke)提(ti)防瞬間掉電(dian)(dian)(dian)(dian)(dian)。磁(ci)(ci)盤(pan)(pan)與供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)連接方(fang)式應(ying)(ying)使鏡像(xiang)副本分別(bie)連接到(dao)不同(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)上。根磁(ci)(ci)盤(pan)(pan)與其(qi)相(xiang)應(ying)(ying)的(de)(de)節(jie)點(dian)應(ying)(ying)由同(tong)一(yi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。特別(bie)是，群集(ji)鎖磁(ci)(ci)盤(pan)(pan)（當重組(zu)群集(ji)時(shi)用(yong)作仲(zhong)裁器）應(ying)(ying)該有(you)冗余電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)，或(huo)者，它能由群集(ji)中(zhong)節(jie)點(dian)之(zhi)外的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。HP 代(dai)表可(ke)提(ti)供(gong)(gong)(gong)關于群集(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)、磁(ci)(ci)盤(pan)(pan)和(he) LAN 硬(ying)(ying)件(jian)布局方(fang)面的(de)(de)詳(xiang)細信息。目前許多磁(ci)(ci)盤(pan)(pan)陣(zhen)列和(he)其(qi)他(ta)架裝(zhuang)系統(tong)含有(you)多個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)，它們應(ying)(ying)部署(shu)為(wei)(wei)設備(bei)上的(de)(de)不同(tong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)連接到(dao)帶有(you)兩個(ge)(ge)(ge)(ge)或(huo)三個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)的(de)(de)*立電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)設備(bei)上，這樣，一(yi)般情況下，只要(yao)出現故(gu)障的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)不超過一(yi)個(ge)(ge)(ge)(ge)，系統(tong)就能繼續正常(chang)運行。因此，如(ru)果群集(ji)中(zhong)的(de)(de)所有(you)硬(ying)(ying)件(jian)有(you)2個(ge)(ge)(ge)(ge)或(huo)3個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)，則要(yao)求至少有(you)三個(ge)(ge)(ge)(ge)*立的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，以(yi)(yi)確保(bao)群集(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)設計(ji)中(zhong)沒(mei)有(you)單點(dian)故(gu)障。
開關(guan)電(dian)(dian)源的(de)(de)工(gong)作過(guo)程相當容(rong)易(yi)理解(jie)，在線(xian)(xian)性(xing)(xing)電(dian)(dian)源中，讓(rang)功(gong)率晶體(ti)管工(gong)作在線(xian)(xian)性(xing)(xing)模式(shi)，與(yu)線(xian)(xian)性(xing)(xing)電(dian)(dian)源不同的(de)(de)是(shi)，PWM開關(guan)電(dian)(dian)源是(shi)讓(rang)功(gong)率晶體(ti)管工(gong)作在導通和關(guan)斷(duan)(duan)的(de)(de)狀態，在這(zhe)兩種狀態中，加在功(gong)率晶體(ti)管上(shang)的(de)(de)伏-安(an)乘積是(shi)很小的(de)(de)（在導通時(shi)，電(dian)(dian)壓(ya)低(di)，電(dian)(dian)流大；關(guan)斷(duan)(duan)時(shi)，電(dian)(dian)壓(ya)高，電(dian)(dian)流小）/功(gong)率器(qi)件上(shang)的(de)(de)伏安(an)乘積就是(shi)功(gong)率半導體(ti)器(qi)件上(shang)所產(chan)生的(de)(de)損(sun)耗(hao)。
與線性電(dian)(dian)源相比，PWM開關電(dian)(dian)源更(geng)為有(you)效的(de)(de)(de)(de)工(gong)作(zuo)過(guo)(guo)程是(shi)通過(guo)(guo)“斬波”，即把輸(shu)(shu)(shu)入(ru)的(de)(de)(de)(de)直流電(dian)(dian)壓(ya)斬成幅值(zhi)等于輸(shu)(shu)(shu)入(ru)電(dian)(dian)壓(ya)幅值(zhi)的(de)(de)(de)(de)脈沖電(dian)(dian)壓(ya)來(lai)實現的(de)(de)(de)(de)。 脈沖的(de)(de)(de)(de)占空比由開關電(dian)(dian)源的(de)(de)(de)(de)控制器來(lai)調(diao)節。一旦輸(shu)(shu)(shu)入(ru)電(dian)(dian)壓(ya)被斬成交(jiao)流方波，其幅值(zhi)就可(ke)以通過(guo)(guo)變(bian)壓(ya)器來(lai)升高(gao)或降低。通過(guo)(guo)增加變(bian)壓(ya)器的(de)(de)(de)(de)二次繞(rao)組數就可(ke)以增加輸(shu)(shu)(shu)出的(de)(de)(de)(de)電(dian)(dian)壓(ya)值(zhi)。*后這(zhe)些交(jiao)流波形經過(guo)(guo)整流濾波后就得到直流輸(shu)(shu)(shu)出電(dian)(dian)壓(ya)。
控制器的(de)(de)主(zhu)要目的(de)(de)是保持輸(shu)出電壓穩(wen)定，其工(gong)作過程與(yu)線性形式的(de)(de)控制器很類(lei)似。也就(jiu)是說控制器的(de)(de)功能塊、電壓參(can)考和(he)誤差放大器，可以設計成與線性調節(jie)器相同(tong)。他們的(de)不同(tong)之處在(zai)于，誤(wu)差放大器的(de)輸出（誤(wu)差電(dian)壓）在(zai)驅動功率管(guan)之前要經過一個(ge)電(dian)壓/脈沖寬(kuan)度轉換(huan)單元(yuan)。開(kai)關(guan)電(dian)源有兩種主要的(de)工作方式：正激式變(bian)換(huan)和升壓式變(bian)換(huan)。盡管(guan)它們各部分的(de)布置差別很小(xiao)，但是工作過程相差很大，在(zai)特定的(de)應用(yong)場合下各有優點。

它的(de)(de)作用(yong)是將交流電(dian)(dian)(dian)(dian)(dian)通過一(yi)個(ge)(ge)(ge)(ge)開(kai)關電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)變(bian)壓(ya)器換為(wei)(wei)5V，-5V，+12V，-12V，+3.3V等穩(wen)定的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)(dian)，以(yi)(yi)供(gong)(gong)(gong)應(ying)(ying)主機(ji)箱內系統(tong)版，軟盤(pan)(pan)，硬(ying)(ying)盤(pan)(pan)驅動及各(ge)種適配器擴展卡等系統(tong)部件(jian)使用(yong)。通俗來(lai)講就是，一(yi)個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)壞了，另一(yi)個(ge)(ge)(ge)(ge)備(bei)份電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)代(dai)替(ti)其(qi)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。可(ke)以(yi)(yi)通過為(wei)(wei)節(jie)點(dian)和(he)磁(ci)(ci)盤(pan)(pan)提(ti)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)池后援來(lai)增(zeng)強硬(ying)(ying)件(jian)的(de)(de)可(ke)用(yong)性(xing)。HP 支持的(de)(de)不間斷電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)（UPS），如(ru) HP PowerTrust，可(ke)提(ti)防瞬間掉電(dian)(dian)(dian)(dian)(dian)。磁(ci)(ci)盤(pan)(pan)與供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)連接方(fang)式應(ying)(ying)使鏡像(xiang)副本分別(bie)連接到(dao)不同(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)上。根磁(ci)(ci)盤(pan)(pan)與其(qi)相(xiang)應(ying)(ying)的(de)(de)節(jie)點(dian)應(ying)(ying)由同(tong)一(yi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。特別(bie)是，群集(ji)鎖磁(ci)(ci)盤(pan)(pan)（當重組(zu)群集(ji)時(shi)用(yong)作仲(zhong)裁器）應(ying)(ying)該有(you)冗余電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)，或(huo)者，它能由群集(ji)中(zhong)節(jie)點(dian)之(zhi)外的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。HP 代(dai)表可(ke)提(ti)供(gong)(gong)(gong)關于群集(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)、磁(ci)(ci)盤(pan)(pan)和(he) LAN 硬(ying)(ying)件(jian)布局方(fang)面的(de)(de)詳(xiang)細信息。目前許多磁(ci)(ci)盤(pan)(pan)陣(zhen)列和(he)其(qi)他(ta)架裝(zhuang)系統(tong)含有(you)多個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)，它們應(ying)(ying)部署(shu)為(wei)(wei)設備(bei)上的(de)(de)不同(tong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)連接到(dao)帶有(you)兩個(ge)(ge)(ge)(ge)或(huo)三個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)的(de)(de)*立電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)設備(bei)上，這樣，一(yi)般情況下，只要(yao)出現故(gu)障的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)不超過一(yi)個(ge)(ge)(ge)(ge)，系統(tong)就能繼續正常(chang)運行。因此，如(ru)果群集(ji)中(zhong)的(de)(de)所有(you)硬(ying)(ying)件(jian)有(you)2個(ge)(ge)(ge)(ge)或(huo)3個(ge)(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)輸(shu)入(ru)，則要(yao)求至少有(you)三個(ge)(ge)(ge)(ge)*立的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，以(yi)(yi)確保(bao)群集(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)路(lu)(lu)設計(ji)中(zhong)沒(mei)有(you)單點(dian)故(gu)障。
開關(guan)電(dian)(dian)源的(de)(de)工(gong)作過(guo)程相當容(rong)易(yi)理解(jie)，在線(xian)(xian)性(xing)(xing)電(dian)(dian)源中，讓(rang)功(gong)率晶體(ti)管工(gong)作在線(xian)(xian)性(xing)(xing)模式(shi)，與(yu)線(xian)(xian)性(xing)(xing)電(dian)(dian)源不同的(de)(de)是(shi)，PWM開關(guan)電(dian)(dian)源是(shi)讓(rang)功(gong)率晶體(ti)管工(gong)作在導通和關(guan)斷(duan)(duan)的(de)(de)狀態，在這(zhe)兩種狀態中，加在功(gong)率晶體(ti)管上(shang)的(de)(de)伏-安(an)乘積是(shi)很小的(de)(de)（在導通時(shi)，電(dian)(dian)壓(ya)低(di)，電(dian)(dian)流大；關(guan)斷(duan)(duan)時(shi)，電(dian)(dian)壓(ya)高，電(dian)(dian)流小）/功(gong)率器(qi)件上(shang)的(de)(de)伏安(an)乘積就是(shi)功(gong)率半導體(ti)器(qi)件上(shang)所產(chan)生的(de)(de)損(sun)耗(hao)。
與線性電(dian)(dian)源相比，PWM開關電(dian)(dian)源更(geng)為有(you)效的(de)(de)(de)(de)工(gong)作(zuo)過(guo)(guo)程是(shi)通過(guo)(guo)“斬波”，即把輸(shu)(shu)(shu)入(ru)的(de)(de)(de)(de)直流電(dian)(dian)壓(ya)斬成幅值(zhi)等于輸(shu)(shu)(shu)入(ru)電(dian)(dian)壓(ya)幅值(zhi)的(de)(de)(de)(de)脈沖電(dian)(dian)壓(ya)來(lai)實現的(de)(de)(de)(de)。 脈沖的(de)(de)(de)(de)占空比由開關電(dian)(dian)源的(de)(de)(de)(de)控制器來(lai)調(diao)節。一旦輸(shu)(shu)(shu)入(ru)電(dian)(dian)壓(ya)被斬成交(jiao)流方波，其幅值(zhi)就可(ke)以通過(guo)(guo)變(bian)壓(ya)器來(lai)升高(gao)或降低。通過(guo)(guo)增加變(bian)壓(ya)器的(de)(de)(de)(de)二次繞(rao)組數就可(ke)以增加輸(shu)(shu)(shu)出的(de)(de)(de)(de)電(dian)(dian)壓(ya)值(zhi)。*后這(zhe)些交(jiao)流波形經過(guo)(guo)整流濾波后就得到直流輸(shu)(shu)(shu)出電(dian)(dian)壓(ya)。
控制器的(de)(de)主(zhu)要目的(de)(de)是保持輸(shu)出電壓穩(wen)定，其工(gong)作過程與(yu)線性形式的(de)(de)控制器很類(lei)似。也就(jiu)是說控制器的(de)(de)功能塊、電壓參(can)考和(he)誤差放大器，可以設計成與線性調節(jie)器相同(tong)。他們的(de)不同(tong)之處在(zai)于，誤(wu)差放大器的(de)輸出（誤(wu)差電(dian)壓）在(zai)驅動功率管(guan)之前要經過一個(ge)電(dian)壓/脈沖寬(kuan)度轉換(huan)單元(yuan)。開(kai)關(guan)電(dian)源有兩種主要的(de)工作方式：正激式變(bian)換(huan)和升壓式變(bian)換(huan)。盡管(guan)它們各部分的(de)布置差別很小(xiao)，但是工作過程相差很大，在(zai)特定的(de)應用(yong)場合下各有優點。
