2019-9-16 鋰電池充電器原理圖是什么呢
鋰(li)離子電(dian)(dian)(dian)池具有單只端電(dian)(dian)(dian)壓高、比容量大等優點，但其充(chong)電(dian)(dian)(dian)必(bi)須使用專用充(chong)電(dian)(dian)(dian)器(qi)(qi)，因為它在過充(chong)電(dian)(dian)(dian)時極(ji)易(yi)損壞。鋰(li)離子電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)器(qi)(qi)之所以稱“新(xin)創意”，是因為它除(chu)監視電(dian)(dian)(dian)池的(de)充(chong)電(dian)(dian)(dian)狀(zhuang)態外，還能分階段控(kong)制(zhi)電(dian)(dian)(dian)池的(de)最(zui)大充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流。用本充(chong)電(dian)(dian)(dian)器(qi)(qi)充(chong)電(dian)(dian)(dian)開(kai)始時，充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流從10mA...

2019-9-2 開關電源的工作模式是什么？有什么特點？
顧(gu)名思義，開(kai)關(guan)電(dian)源就是利用電(dian)子(zi)開(kai)關(guan)器件(jian)（如晶體(ti)管、場(chang)效(xiao)應管、可控(kong)(kong)硅閘流管等），通過控(kong)(kong)制(zhi)電(dian)路，使電(dian)子(zi)開(kai)關(guan)器件(jian)不停地“接(jie)通”和(he)(he)“關(guan)斷”，讓電(dian)子(zi)開(kai)關(guan)器件(jian)對(dui)輸(shu)入電(dian)壓(ya)進行脈沖(chong)調(diao)制(zhi)，從而實現DC/AC、DC/DC電(dian)壓(ya)變換，以及(ji)輸(shu)出電(dian)壓(ya)可調(diao)和(he)(he)自動穩壓(ya)。...
