style="text-indent:25px">直流電源中的非靜電力是由負(fù)極指向正極的。當(dāng)直流電源與外電路接通后，在電源外部（外電路），由于電場(chǎng)力的推動(dòng)，形成由正極到負(fù)極的電流。而在電源內(nèi)部（內(nèi)電路），非靜電力的作用則使電流由負(fù)極流到正極，從而使電荷的流動(dòng)形成閉合的循環(huán)。表現(xiàn)電源本身的一個(gè)重要特征量是電源的電動(dòng)勢(shì)，它等于單位正電荷從負(fù)極通過(guò)電源內(nèi)部移到正極時(shí)非靜電力所作的功。當(dāng)電源的內(nèi)電阻可以忽略不計(jì)時(shí)，可以認(rèn)為電源的電動(dòng)勢(shì)在量值上近似地等于電源兩極間的電位差或電壓。為了取得較高的直流電壓，常將直流電源串聯(lián)使用，這時(shí)總電動(dòng)勢(shì)為各電源的電動(dòng)勢(shì)之和，總內(nèi)阻也為各電源內(nèi)電阻之和。由于內(nèi)阻增大，一般只能用于所需電流強(qiáng)度較小的電路。為了取得較大的電流強(qiáng)度，可以將等電動(dòng)勢(shì)的直流電源并聯(lián)使用，這時(shí)總電動(dòng)勢(shì)即為單個(gè)電源的電動(dòng)勢(shì)，總內(nèi)阻為各電源內(nèi)電阻的并聯(lián)值。</p><p style="text-indent:25px">3）通信電源通信電源其實(shí)質(zhì)上就是DC/DC變換器式電源，只是它一般以直流－48V或－24V供電，并用后備電池作DC供電的備份，將DC的供電電壓變換成電路的工作電壓，一般它又分**供電、分層供電和單板供電三種，以后者可靠性比較高。（4）電臺(tái)電源電臺(tái)電源輸入AC220V/110V，輸出DC13.8V,功率由所供電臺(tái)功率而定，幾安幾百安均有產(chǎn)品。為防止AC電網(wǎng)斷電影響電臺(tái)工作，而需要有電池組作為備份，所以此類電源除輸出一個(gè)13.8V直流電壓外,還具有對(duì)電池充電自動(dòng)轉(zhuǎn)換功能。（5）模塊電源隨著科學(xué)技術(shù)飛速發(fā)展，對(duì)電源可靠性、容量/體積比要求越來(lái)越高，模塊電源越來(lái)越顯示其優(yōu)越性，它工作頻率高、體積小、可靠性高，便于安裝和組合擴(kuò)容，所以越來(lái)越被***采用。國(guó)內(nèi)雖有相應(yīng)模塊生產(chǎn)，但因生產(chǎn)工藝未能趕上國(guó)際水平，故障率較高。DC/DC模塊電源雖然成本較高，但從產(chǎn)品的漫長(zhǎng)的應(yīng)用周期的整體成本來(lái)看，特別是因系統(tǒng)故障而導(dǎo)致的高昂的維修成本及商譽(yù)損失來(lái)看，選用該電源模塊還是合算合算的，在此還值得一提的是羅氏變換器電路，它的突出優(yōu)點(diǎn)是電路結(jié)構(gòu)簡(jiǎn)單，效率高和輸出電壓、電流的紋波值接近于零。高頻開(kāi)關(guān)直流電源多少錢(qián)。</p><div
