在線式不間斷逆變電源裝置的設計

摘要：　　本文介紹了在線式不間斷逆變電源裝置的系統結構和工作原理，并對其控制方法和控制電路進行了研究。在此基礎上，研制了一臺實驗樣機。實驗結果表明，該裝置具有穩壓、穩頻、濾波和抗干擾等功能。輸出具有高的利用率和低諧波失真的純凈正弦波。 敘詞：在線式 不間斷逆變電源 Abstract：　　The paper introduces the system configure and operation principle of On-line UPS device, and analyzes its control method and circuit. A prototype is manufactured according to them. The experiment results indicate that On-line UPS device has the function of stabilizing the voltage and frequency ,filtering and resisting the interaction. The dive output the pure sine wave with high rate of voltage use and low distortion of harmonic wave.. Keyword：On-line UPS
