“電(dian)源”是個非常籠統的(de)(de)詞、手機充(chong)電(dian)器、筆(bi)記(ji)本電(dian)源適(shi)配器、監控電(dian)源、工業電(dian)源都可以(yi)稱之(zhi)為“電(dian)源”。而開關電(dian)源則是電(dian)源中的(de)(de)一個分類(lei)，也是我們平時日(ri)常中接觸的(de)(de)的(de)(de)。那么究竟(jing)什么是開關電(dian)源呢?今天電源適(shi)配器廠家(jia)就(jiu)來為大家簡單的講解一(yi)下吧。

開關(guan)電(dian)(dian)源就是通過開關(guan)管的開通和關(guan)斷來實(shi)現(xian)電(dian)(dian)能(neng)(neng)的變換。電(dian)(dian)能(neng)(neng)的變換則包括：

1，AC/DC。將(jiang)交(jiao)流變換為直流，通常是將(jiang)來(lai)自電(dian)網(wang)的220V、兩相交(jiao)流電(dian)或380V、三相交(jiao)流電(dian)轉(zhuan)換為直流電(dian)。小功率AC/DC的交(jiao)流輸入是220V，大功率的交(jiao)流輸入是380V。根據應用行業、場(chang)合不同(tong)，又被稱(cheng)為AC／DC變換器，整流器，一(yi)次電(dian)源，通信電(dian)源，電(dian)源適(shi)配器，照明電(dian)源等。

2，DC/DC。將(jiang)直流(liu)(liu)變(bian)換為(wei)(wei)直流(liu)(liu)，譬如將(jiang)高壓、小電流(liu)(liu)轉換為(wei)(wei)低壓、大電流(liu)(liu)，根(gen)據應(ying)用行業(ye)、場合不同，可(ke)能稱為(wei)(wei)DC/DC變(bian)換器，二次(ci)電源(yuan)，模(mo)塊電源(yuan)，板上電源(yuan)，等。

3，DC/AC。將直流(liu)變換為交(jiao)流(liu)，根(gen)據(ju)應用行業、場合不同(tong)，可能稱為UPS，逆變器(qi)(qi)，并網逆變器(qi)(qi)，電機控制器(qi)(qi)，等。

4，AC/AC。將交(jiao)流(liu)變換為交(jiao)流(liu)，通(tong)常的產品形式是變頻器，用于電機控制(zhi)方面。

開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)還可以(yi)分為“一次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)”和“二(er)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)”。一次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)一般特指給電(dian)(dian)(dian)(dian)(dian)(dian)信機(ji)房供電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)48V電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。二(er)次(ci)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)則是(shi)客戶(hu)定制電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，計算(suan)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，筆記本電(dian)(dian)(dian)(dian)(dian)(dian)腦等(deng)各種電(dian)(dian)(dian)(dian)(dian)(dian)器設備的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器，手機(ji)充電(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，充電(dian)(dian)(dian)(dian)(dian)(dian)樁電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，車(che)載充電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)，車(che)載DC／DC變換(huan)器，照明電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)等(deng)，以(yi)上就是(shi)有關開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)一些知(zhi)識經(jing)過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配廠家的(de)(de)介紹后，是(shi)不是(shi)清(qing)楚了很(hen)多呢？
