解決方案介紹：

鼎漢技(ji)術(shu)CRH3型動車(che)組輔助電源(yuan)系統解決(jue)方案，包含了(le)單輔助變(bian)(bian)流器、充電機(ji)和單相(xiang)逆(ni)變(bian)(bian)器。

-- 輔助變流器(qi)將(jiang)牽引變流器(qi)中(zhong)間直流環節的直流電轉換為(wei)三(san)相440V/60Hz交(jiao)流電，為(wei)車載設備提供中(zhong)壓電源。

-- 充(chong)電(dian)(dian)(dian)機(ji)將車(che)上(shang)中(zhong)壓母線的440V/60Hz三相交(jiao)流電(dian)(dian)(dian)轉換成(cheng)隔離的110V直流電(dian)(dian)(dian)，向列車(che)上(shang)所(suo)有與充(chong)電(dian)(dian)(dian)機(ji)連接的直流負載供電(dian)(dian)(dian)，同時(shi)對蓄電(dian)(dian)(dian)池(chi)組進行充(chong)電(dian)(dian)(dian)。

-- 單相逆(ni)變器將列車110V直流電(dian)轉換成(cheng)隔離的220V單相交流電(dian)，為車廂內的負(fu)載提供穩壓(ya)、穩頻的純凈電(dian)源。
