2019-9-16 大功率充電機和大功率充電器有什么區別
大功(gong)率充(chong)(chong)電(dian)(dian)(dian)機采用(yong)了(le)功(gong)能完善(shan)的(de)電(dian)(dian)(dian)源IC，并(bing)由數(shu)字邏輯電(dian)(dian)(dian)路進行(xing)實行(xing)采樣控(kong)制(zhi)，自動檢測所充(chong)(chong)蓄(xu)電(dian)(dian)(dian)池的(de)狀態。該充(chong)(chong)電(dian)(dian)(dian)機采用(yong)了(le)“恒(heng)流-恒(heng)壓限流-恒(heng)壓浮(fu)充(chong)(chong)”充(chong)(chong)電(dian)(dian)(dian)模式(shi)，達到了(le)全自動工(gong)作(zuo)狀態，特(te)別適(shi)合無人(ren)值守(shou)的(de)工(gong)作(zuo)場合。優質元器件的(de)選用(yong)保證了(le)產品本身的(de)可靠(kao)性(xing)和...
2019-9-16 鋰電池充電器原理圖是什么呢
鋰(li)離子(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)具有單只(zhi)端(duan)電(dian)(dian)(dian)壓高、比容量大等優點(dian)，但(dan)其充(chong)電(dian)(dian)(dian)必須使用專(zhuan)用充(chong)電(dian)(dian)(dian)器，因為它(ta)在過充(chong)電(dian)(dian)(dian)時(shi)極易(yi)損壞。鋰(li)離子(zi)電(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)電(dian)(dian)(dian)器之所以稱(cheng)“新創(chuang)意”，是因為它(ta)除監視電(dian)(dian)(dian)池(chi)(chi)(chi)的充(chong)電(dian)(dian)(dian)狀態外(wai)，還能分(fen)階段(duan)控(kong)制(zhi)電(dian)(dian)(dian)池(chi)(chi)(chi)的最大充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)。用本充(chong)電(dian)(dian)(dian)器充(chong)電(dian)(dian)(dian)開始時(shi)，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)從10mA...

開(kai)關(guan)電源的工(gong)作(zuo)過程相當(dang)容易(yi)理解，在(zai)(zai)線性(xing)電源中，讓功(gong)率(lv)(lv)晶(jing)體管(guan)工(gong)作(zuo)在(zai)(zai)線性(xing)模式，與(yu)線性(xing)電源不(bu)同(tong)的是(shi)，PWM開(kai)關(guan)電源是(shi)讓功(gong)率(lv)(lv)晶(jing)體管(guan)工(gong)作(zuo)在(zai)(zai)導(dao)通和關(guan)斷的狀態，在(zai)(zai)這兩種狀態中，加在(zai)(zai)功(gong)率(lv)(lv)晶(jing)體管(guan)上的伏-安乘積(ji)是(shi)很小的（在(zai)(zai)導(dao)通時，電壓低，電流大；關(guan)斷時，電壓高...
2019-9-2 開關電源的工作模式是什么？有什么特點？
顧名思義，開關電(dian)(dian)源(yuan)就是利用電(dian)(dian)子開關器(qi)(qi)件(jian)（如(ru)晶(jing)體管、場效應管、可控(kong)硅(gui)閘流管等），通過控(kong)制電(dian)(dian)路，使電(dian)(dian)子開關器(qi)(qi)件(jian)不(bu)停地“接(jie)通”和“關斷”，讓電(dian)(dian)子開關器(qi)(qi)件(jian)對輸入電(dian)(dian)壓(ya)進行(xing)脈(mo)沖調制，從而實現DC/AC、DC/DC電(dian)(dian)壓(ya)變換，以及輸出(chu)電(dian)(dian)壓(ya)可調和自動(dong)穩壓(ya)。...
