    傳統交流UPS的幾大缺陷

    文字:[大][中][小] 2016-6-22    瀏覽次數:1596    

    因為計算機等電器設備都采用了高可靠穩定的開關電源,供電部門一年內不會多次停電,大部分情況下可取消UPS。傳統交流UPS的主要缺點是:

    (1)電路設計復雜.制造困難.體積大、故障率高,浪費能源和人力。

    (2)不能給空調和電動機(因感性負載的起動沖擊電流大)供電,中小功率交流UPS甚至不能向復印機、打印機、電磁爐、日光燈供電。

    (3)許多UPS用戶發現,不用交流UPS反而更安全,取消交流逆變器已成為時代發展的大趨勢。

    傳統交流UPS與眾多用電設備之間的電路連接中心區域的逆變器和再次整流濾波電路是直流不間斷電源完全可以州掉的多余設計。
