開關(guān)電源的優(yōu)點(diǎn)是體積小，重量輕，穩(wěn)定可靠；缺點(diǎn)相對于線性電源來說紋波較大（一般≤1%VO（P-P），好的可做到十幾mV（P-P）或更小）。它的功率可自幾瓦－幾千瓦均有產(chǎn)品。價(jià)位為3元－十幾萬元/瓦，下面就一般習(xí)慣分類介紹幾種開關(guān)電源： </p> <p> 1、AC/DC電源 </p> <p> 該類電源也稱一次電源——AC是交流，DC是直流，它自電網(wǎng)取得能量，經(jīng)過高壓整流濾波得到一個(gè)直流高壓，供DC/DC變換器在輸出端獲得一個(gè)或幾個(gè)穩(wěn)定的直流電壓，功率從幾瓦－幾千瓦均有產(chǎn)品，用于不同場合。屬此類產(chǎn)品的規(guī)格型號繁多，據(jù)用戶需要而定通信電源中的一次電源（AC220輸入，DC48V或24V輸出)也屬此類. </p> <p> 2、DC/DC電源 </p> <p> 在通信系統(tǒng)中也稱二次電源，它是由一次電源或直流電池組提供一個(gè)直流輸入電壓，經(jīng)DC/DC變換以后在輸出端獲一個(gè)或幾個(gè)直流電壓。 </p> <p> 3、通信電源 </p> <p> 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。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img
