傳統大功率充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機由于采(cai)用(yong)的(de)(de)(de)是變壓(ya)器變壓(ya)整(zheng)流、可控硅控制的(de)(de)(de)方(fang)法,因此設(she)備笨重,可靠性差(cha)。電(dian)(dian)(dian)(dian)(dian)(dian)瓶充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機、汽(qi)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機、汽(qi)車(che)電(dian)(dian)(dian)(dian)(dian)(dian)瓶充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)汽(qi)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機、電(dian)(dian)(dian)(dian)(dian)(dian)動(dong)叉車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)(de)蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian),共同面(mian)臨的(de)(de)(de)一(yi)大問題是這種小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)流慢充(chong)(chong)(chong)方(fang)式,蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)初充(chong)(chong)(chong)所需時間(jian)非常長,充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流遠小(xiao)于蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)可接受的(de)(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)流,不僅耗(hao)時長,且能源利(li)用(yong)不充(chong)(chong)(chong)分。
為了(le)提高大(da)功率充電機(ji)充電效(xiao)率,使運營成本降低,設計以大(da)功率IGBT為核(he)心的智能(neng)型全(quan)自動(dong)快速充電機(ji)勢(shi)在必行,這種技術還具有節能(neng)環(huan)保(bao)等諸方面的社會意義。
大功率充電機采用多個電源模塊并聯供電的方式來實現大功率的輸出。如果產生的諧波如果沒有被有效控制,將會污染電網。因此,大功率充電機中須采用并聯均流策略來平衡負載電流分配,實現了充電機低諧波高功率因素運行,改善了充電機并聯均流性能。上海施(shi)能電器設(she)備(bei)有限公司始建于1984年,上海市高新技術企業,中國工業車輛優秀配套供應商,上海電器行業名優產品,主要生產工頻系列充電機,高頻系列充電機,鋰電池充電機系列放電機系列充放電機等電器產品。
