    • 對於不斷電系統的控制器，快速的運算表示可以在同一個時間內可做大量的運算。FPGA的運算流程直接且快速的，所以使用FPGA控制器可以完成快速且複雜的運算。
    本論文採用FPGA的方式來控制不斷電系統，FPGA不但可以寫入複雜的演算法，以達到不斷線系統得控制需求，也可以進行平行處裡運算，以達到快速的系統控制運算速度。此外，系統單晶片控制可以經過數位晶片的製程流程後製作成為數位晶片。
    使用FPGA(DE1-SoC)驗證功能與實作不斷電系統，輸入電網電壓為220V、電池電壓為70V、輸出電壓為220V、輸出最大功率為2000W。

    For the controller of Uninterruptible Power Supply, fast calculation speed means to do large calculation in s short time. The calculation method of FPGA is direct and fast, so FPGA controller is able to reach fast and complex calculation.
    FPGA is used for uninterruptible power supplies control in the thesis. System on chip is not only able to contain complex algorithm to reach uninterruptible power supplies requirements, but also able to use parallel process to get faster calculation speed. Besides, digital IC is made by FPGA through digital IC process.
    Use the field programmable gate array (FPGA) to verify the circuit and the digital controller are presented. A prototype converter with the input AC voltage 220Vr.m.s., output voltage 220Vr.m.s., battery voltage 70V and output power 400W ~ 2000W is implemented to verify the theoretical.
