輸出的交流電壓源具有較低諧波失真，且在負載變動下有較佳的強健性。
單相直流至交流電源轉換器在實際的應用上會遭遇到不同型態的負載，如線
性負載、整流性負載等等，在不同的負載操作下會使得電源轉換系統的輸出電源
品質受到影響，為了有效的提高電源轉換器的供應品質，必須對於電源轉換系統
加以控制，以追求高品質的交流電壓源輸出。本論文致力於在不同負載操作下改
善電源轉換系統的電壓總諧波失真。其中重複控制器用來設計消除週期性擾動訊
號，此控制器應用在單相直流對交流電源轉換器能有效的抑制諧波失真，並結合
了迴授擾動調變技術與最佳化狀態迴授控制，使得電源轉換器對於負載變動有較
佳的強健性。
實現本論文單相直流對交流電源轉換器的架構，使用場效可規劃邏輯陣列元
件(Field-Programmable Gate Arrays, FPGA)做為數位化控制之核心，實際測試後證
明，輸出電壓總諧波失真(THD)操作在無載、線性負載以及非線性負載的情況下皆
可以壓抑在 0.5%以下，展現了優異的效能與強健性。

This thesis applies digital repetitive control to a single-phase DC-to-AC converter,
with some proposed designs to improve stability and enhance performance of the
converter under various load variations.
A practical DC-to-AC converter is required to convert DC power to stable AC
power with low harmonic distortion when attached to various linear or nonlinear loads.
This thesis combines repetitive control with feedback dithering modulation and optimal
state feedback to control the converter. The repetitive control is responsible for
regulating output power and eliminating harmonics, while the feedback dithering
modulation for switching the power transistors with reduced switching noise and the
state feedback for stabilizing the converter under various load variations.
The presented control and modulation schemes of the power converter are
implemented on an FPGA (Field Programmable Gate Array). The experiments confirm
the excellent performance and robustness of the converter, indicating a total harmonic
distortion of less than 0.5% for the converter when attached to various linear or
nonlinear loads.
