Description
本發明係有關一種不斷電系統,尤指一種應用於對負載提供市電模式或電池模式的不斷電系統。The present invention relates to an uninterrupted power system, especially an uninterrupted power system applied to provide a commercial power mode or a battery mode to a load.
一般而言,具有功率因數修正(Power Factor Correction, PFC)功能的轉換器應用於目前不斷電系統(Uninterruptible Power System, UPS)的3kVA架構下之電池模式時,在電網異常或停電的情況下不間斷地為電器等負載設備提供備援交流電源的供電,以維持電器正常運作的設備。通常情況下不斷電系統被用於維持電腦、伺服器等關鍵性商用設備或精密儀器的不間斷的供電,防止數據損失、通訊中斷或裝置失去控制。Generally speaking, when a converter with Power Factor Correction (PFC) function is used in the battery mode of the current 3kVA architecture of the Uninterruptible Power System (UPS), in the event of an abnormal power grid or a power outage Equipment that continuously provides backup AC power supply to load equipment such as electrical appliances to maintain the normal operation of electrical appliances.

Lead-acid batteries are large in size, short in life, and time-consuming and costly in maintenance. And the traditional DC-to-DC (DC-to-DC) converter is a push-pull (Push-Pull) architecture, which is different from the Boost circuit at one end of the AC power grid. As a result, it will occupy too much wiring area on the circuit board, increase the substrate material and process time of the circuit board, and due to the size of the lead-acid battery and the increase of the Push-Pull circuit structure, the volume and cost of the uninterruptible power system will increase accordingly. .

如前所述,在使用本發明所述之不斷電系統時,如交流電源正常,交流電源通過第二電路20以及第三電路30對負載200提供市電模式的供電,其中,第二電路20以及第三電路30可以對交流電源進行電壓轉換處理(例如:Boost升壓)之後提供給負載200;如交流電源異常(例如:突波、欠電壓或停電),第一電路10的第一功率開關電路11以及第二電路20的第二功率開關電路22與第三功率開關電路23可以透過電路的導通與關斷控制,使得備援電池B1輸出的電能可以通過第一功率開關電路11進入第二電路20以及第三電路30進行電壓轉換處理,使得備援電池B1通過第一功率開關電路11、第二電路20以及第三電路30對負載200提供電池模式的供電。As mentioned above, when using the uninterrupted power system of the present invention, if the AC power supply is normal, the AC power supply provides power supply in the commercial mode to the
為此,在交流電源異常時,僅透過第一功率開關電路11,即可使得備援電池B1通過第二電路20以及第三電路30進行電壓轉換處理,而不需要額外獨立於交流電源流經路徑之外的其他電壓轉換電路(例如:Push-Pull轉換器),本發明透過線路架構簡化的改進,不需要佔據額外的電路板體積與其佈線面積,可以減少電路板基材與製程時間,進而解決不斷電系統之體積與成本增加的技術問題,而達到降低生產成本、提高生產效率以及使用上便攜使用之目的。For this reason, when the AC power supply is abnormal, only the first
除此之外,本發明所述備援電池B1並不是採用傳統的鉛酸電池,而是採用鋰電池搭配使用,習用已知的鉛酸電池具有體積大、重量重、使用壽命短的缺點,為此,本發明所述之不斷電系統更具有體積小、重量輕、使用壽命與可靠度較佳等的其他優點。In addition, the backup battery B1 of the present invention does not use a traditional lead-acid battery, but a lithium battery. The conventionally known lead-acid battery has the disadvantages of large volume, heavy weight, and short service life. For this reason, the uninterruptible power system of the present invention has other advantages such as small size, light weight, better service life and reliability.
