高頻開關電源創新與發展
高頻開關電源隨著電力系統的(de)應用而得到(dao)更多的(de)創新與發展(zhan)。
目前，我國電力系統采用的直流電源也正由傳統的相控電源逐步向模塊化的高頻轉變。高頻開關電源整流器的工作原理：交流電源接入整流模塊，經濾波及三相全波整流器后變成直流，再接入高頻逆變回路，將直流轉換為高頻交流，最后經高頻變壓器、整流橋、濾波器后輸出平穩直流。這種高頻開關電源主要由(you)高(gao)頻開(kai)關充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)模塊、集中(zhong)監控(kong)(kong)器(qi)和蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)等組(zu)(zu)成，其中(zhong)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)模塊和集中(zhong)監控(kong)(kong)器(qi)具有內置(zhi)微(wei)處(chu)理器(qi)，智能(neng)化(hua)程(cheng)度高(gao)。高(gao)頻系統正常運行(xing)(xing)時，充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機的(de)(de)輸出(chu)與蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)并(bing)聯運行(xing)(xing)，給(gei)經常性負荷(he)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，同時對(dui)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)進(jin)行(xing)(xing)浮(fu)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，以補(bu)充(chong)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)自放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。當交流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)輸入中(zhong)斷后，由(you)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組(zu)(zu)給(gei)負荷(he)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，以保(bao)證對(dui)負荷(he)連續不間(jian)斷供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，當交流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)恢復正常后，系統自動(dong)對(dui)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)進(jin)行(xing)(xing)均充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，對(dui)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)大(da)量放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后進(jin)行(xing)(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的(de)(de)快(kuai)速補(bu)充(chong)。
