傳統大(da)功率(lv)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)由于(yu)采用的(de)(de)(de)是變壓(ya)器變壓(ya)整流、可(ke)(ke)控硅(gui)控制的(de)(de)(de)方(fang)法,因此設備笨重(zhong),可(ke)(ke)靠性(xing)差。電(dian)(dian)(dian)(dian)瓶(ping)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)、汽車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)、汽車(che)電(dian)(dian)(dian)(dian)瓶(ping)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)、電(dian)(dian)(dian)(dian)動汽車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)、電(dian)(dian)(dian)(dian)動叉車(che)充(chong)(chong)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)蓄電(dian)(dian)(dian)(dian)池的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian),共(gong)同面臨(lin)的(de)(de)(de)一大(da)問(wen)題是這種小電(dian)(dian)(dian)(dian)流慢充(chong)(chong)方(fang)式,蓄電(dian)(dian)(dian)(dian)池初充(chong)(chong)所需時間(jian)非(fei)常長,充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流遠小于(yu)蓄電(dian)(dian)(dian)(dian)池可(ke)(ke)接受的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流,不僅(jin)耗時長,且能源(yuan)利用不充(chong)(chong)分(fen)。
為(wei)了提高大(da)功(gong)率充(chong)(chong)(chong)電機充(chong)(chong)(chong)電效率,使運營(ying)成本降低,設計以大(da)功(gong)率IGBT為(wei)核心的(de)智(zhi)能型全(quan)自動快速(su)充(chong)(chong)(chong)電機勢在必行,這(zhe)種技術還(huan)具有(you)節能環保等諸方面的(de)社會意義(yi)。
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。上海施能電器設備有(you)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。
