2019-10-8 開關電源的基本類型有哪些呢？
現代開關電(dian)(dian)(dian)(dian)源(yuan)(yuan)有兩種：一(yi)種是直(zhi)流(liu)開關電(dian)(dian)(dian)(dian)源(yuan)(yuan)；另(ling)一(yi)種是交流(liu)開關電(dian)(dian)(dian)(dian)源(yuan)(yuan)。這(zhe)里主要介紹的只是直(zhi)流(liu)開關電(dian)(dian)(dian)(dian)源(yuan)(yuan)，其功能是將(jiang)電(dian)(dian)(dian)(dian)能質量較差(cha)的原生態電(dian)(dian)(dian)(dian)源(yuan)(yuan)（粗電(dian)(dian)(dian)(dian)），如市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)(yuan)或蓄(xu)電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)源(yuan)(yuan)，轉換成滿足設備要求的質量較高的直(zhi)流(liu)電(dian)(dian)(dian)(dian)壓(ya)（精電(dian)(dian)(dian)(dian)）。直(zhi)流(liu)開關電(dian)(dian)(dian)(dian)源(yuan)(yuan)的核(he)心是DC/DC...
2019-9-16 大功率充電機和大功率充電器有什么區別

2019-9-16 鋰電池充電器原理圖是什么呢
鋰離子電(dian)(dian)(dian)池具有單只端(duan)電(dian)(dian)(dian)壓高、比容(rong)量大等優(you)點，但其(qi)充(chong)(chong)(chong)電(dian)(dian)(dian)必須(xu)使用專用充(chong)(chong)(chong)電(dian)(dian)(dian)器，因為(wei)它在(zai)過充(chong)(chong)(chong)電(dian)(dian)(dian)時極易損壞。鋰離子電(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)器之所以(yi)稱“新(xin)創意”，是因為(wei)它除(chu)監視電(dian)(dian)(dian)池的充(chong)(chong)(chong)電(dian)(dian)(dian)狀態(tai)外，還能分階(jie)段控制(zhi)電(dian)(dian)(dian)池的最(zui)大充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流。用本充(chong)(chong)(chong)電(dian)(dian)(dian)器充(chong)(chong)(chong)電(dian)(dian)(dian)開始時，充(chong)(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流從10mA...
2019-9-10 開關電源的工作原理是什么呢？
開關(guan)電(dian)源(yuan)的工作過程相當容易理(li)解，在(zai)線性(xing)電(dian)源(yuan)中(zhong)，讓功率晶(jing)體(ti)管工作在(zai)線性(xing)模式，與線性(xing)電(dian)源(yuan)不同(tong)的是，PWM開關(guan)電(dian)源(yuan)是讓功率晶(jing)體(ti)管工作在(zai)導通和關(guan)斷的狀態，在(zai)這(zhe)兩種狀態中(zhong)，加在(zai)功率晶(jing)體(ti)管上的伏-安乘積是很小的（在(zai)導通時(shi)，電(dian)壓低，電(dian)流大；關(guan)斷時(shi)，電(dian)壓高...
2019-9-2 開關電源的工作模式是什么？有什么特點？
顧名(ming)思義，開(kai)關電(dian)(dian)源(yuan)就(jiu)是利用電(dian)(dian)子(zi)開(kai)關器(qi)件(jian)（如晶體管(guan)、場(chang)效應(ying)管(guan)、可控(kong)硅閘流管(guan)等），通過(guo)控(kong)制(zhi)(zhi)電(dian)(dian)路，使電(dian)(dian)子(zi)開(kai)關器(qi)件(jian)不停地“接通”和“關斷”，讓電(dian)(dian)子(zi)開(kai)關器(qi)件(jian)對輸入電(dian)(dian)壓進(jin)行(xing)脈(mo)沖調制(zhi)(zhi)，從而實現DC/AC、DC/DC電(dian)(dian)壓變(bian)換，以及輸出電(dian)(dian)壓可調和自動穩壓。...
