如果蓄電池充(chong)電機變壓(ya)器次級的電壓(ya)反饋(kui)(kui)回路開路，即分壓(ya)電阻(zu)開路，反饋(kui)(kui)電壓(ya)不(bu)能(neng)輸入ＰＷＭ脈寬調制芯(xin)片(pian)(pian)輸入腳(jiao)，或(huo)者初(chu)級線(xian)圈(quan)電流過大，脈寬調制芯(xin)片(pian)(pian)SG3525過流保護工作，或(huo)者光耦合器PC817故障(zhang)，SG3525的輸出脈沖信號不(bu)能(neng)送(song)到專用驅動(dong)芯(xin)片(pian)(pian)I...
2019-3-25 造成大功率蓄電池充電機電壓過高現象的原因
造成大(da)功(gong)率蓄電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)機(ji)電(dian)(dian)(dian)壓過高現象的(de)原因有兩(liang)類。一(yi)類情況是大(da)功(gong)率蓄電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)機(ji)中穩壓部分的(de)元件質量出現問題，使開關(guan)管(guan)的(de)導(dao)(dao)通(tong)時(shi)(shi)間變短，儲能減少，電(dian)(dian)(dian)源端(duan)能量的(de)補(bu)充(chong)跟(gen)不上負載端(duan)電(dian)(dian)(dian)能消耗的(de)需(xu)要。檢測的(de)重點是影響開關(guan)管(guan)導(dao)(dao)通(tong)時(shi)(shi)間的(de)電(dian)(dian)(dian)路(lu)。 ①取樣電(dian)(dian)(dian)路(lu)。...
2019-3-19 充電機快速充電原理
蓄電(dian)池(chi)充(chong)(chong)(chong)電(dian)機的種類(lei)很(hen)多，目前應用最廣的主要是密(mi)封鉛酸蓄電(dian)池(chi)和鎳鎘(ge)電(dian)池(chi)。這2種蓄電(dian)池(chi)的充(chong)(chong)(chong)放(fang)電(dian)原理都是一樣的，即都是通過(guo)化學反應產生(sheng)正負離子形成(cheng)電(dian)流。 蓄電(dian)池(chi)充(chong)(chong)(chong)電(dian)機的電(dian)池(chi)在充(chong)(chong)(chong)放(fang)電(dian)的過(guo)程中會產生(sheng)氧...
2019-3-19 充電器總體硬件設計
由于充(chong)(chong)電(dian)(dian)(dian)對象是鉛酸蓄電(dian)(dian)(dian)池，設計中采(cai)用電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓負反饋的(de)方法(fa)來達(da)到恒(heng)流、恒(heng)壓充(chong)(chong)電(dian)(dian)(dian)的(de)目的(de)，并(bing)對充(chong)(chong)電(dian)(dian)(dian)過程各種工作參量(liang)進行實時(shi)監(jian)測及智(zhi)能多段式(shi)充(chong)(chong)電(dian)(dian)(dian)策略的(de)精確控(kong)制，應用了LPC933單片機(ji)及相應的(de)控(kong)制電(dian)(dian)(dian)路。充(chong)(chong)電(dian)(dian)(dian)器(qi)硬件(jian)原理圖(tu)(tu)如圖(tu)(tu)1所示。 充(chong)(chong)電(dian)(dian)(dian)器(qi)電(dian)(dian)(dian)路主...
