  2020-2-6 使用直流穩壓電源需要注意哪些事項？

  直(zhi)(zhi)流穩壓(ya)(ya)電(dian)(dian)源是一種可(ke)以幫(bang)助(zhu)負載提(ti)供穩定(ding)直(zhi)(zhi)流電(dian)(dian)源的電(dian)(dian)子裝置。直(zhi)(zhi)流穩壓(ya)(ya)電(dian)(dian)源所(suo)提(ti)供的是交(jiao)流電(dian)(dian)源，電(dian)(dian)量(liang)在(zai)于夠大(da)，當交(jiao)流供電(dian)(dian)電(dian)(dian)源的電(dian)(dian)壓(ya)(ya)或負載電(dian)(dian)阻變化時,穩壓(ya)(ya)器的直(zhi)(zhi)流輸(shu)出電(dian)(dian)壓(ya)(ya)都(dou)會保持穩定(ding)。下面小編給(gei)大(da)家詳細介紹使用直(zhi)(zhi)流穩壓(ya)(ya)電(dian)(dian)源過程中需要注意的幾(ji)個事項。...

  2019-10-8 開關電源的基本類型有哪些呢？

  現代開關(guan)(guan)電(dian)(dian)(dian)源(yuan)有兩種：一種是直流開關(guan)(guan)電(dian)(dian)(dian)源(yuan)；另一種是交(jiao)流開關(guan)(guan)電(dian)(dian)(dian)源(yuan)。這里主要介紹的(de)只是直流開關(guan)(guan)電(dian)(dian)(dian)源(yuan)，其(qi)功能是將電(dian)(dian)(dian)能質(zhi)量(liang)較差的(de)原生態電(dian)(dian)(dian)源(yuan)（粗電(dian)(dian)(dian)），如市電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)或(huo)蓄電(dian)(dian)(dian)池電(dian)(dian)(dian)源(yuan)，轉換成滿足設備(bei)要求的(de)質(zhi)量(liang)較高的(de)直流電(dian)(dian)(dian)壓（精電(dian)(dian)(dian)）。直流開關(guan)(guan)電(dian)(dian)(dian)源(yuan)的(de)核(he)心是DC/DC...

  2019-9-2 開關電源的工作模式是什么？有什么特點？

  顧名思義，開(kai)關(guan)電源就是利用電子開(kai)關(guan)器(qi)件(jian)（如晶體管(guan)、場效應(ying)管(guan)、可控硅閘流管(guan)等(deng)），通(tong)過(guo)控制電路，使電子開(kai)關(guan)器(qi)件(jian)不停地(di)“接通(tong)”和“關(guan)斷”，讓電子開(kai)關(guan)器(qi)件(jian)對(dui)輸(shu)入電壓(ya)(ya)進行脈沖調制，從而(er)實現(xian)DC/AC、DC/DC電壓(ya)(ya)變換，以及輸(shu)出電壓(ya)(ya)可調和自(zi)動穩壓(ya)(ya)。...
