隨著電力電子技術的飛速發展，電能轉換器已經應用于市電並網、不間斷供電系統、馬達驅動等很多領域。随着新能源发电的发展和电力传输要求的提高，关于高功率转换器的研究受到越来越多的重视。針對於高壓設備，電能轉換器中的開關需要可以承受相當高的電壓。多階層轉換器為高壓設備提供了重要的解決方案。
本研究製作一部基於分切合整數位控制的多階層模組化雙向轉換器。多階層模組化轉換器廣泛應用於靜態同步補償器、高壓直流輸電、可再生能源發電及電池儲能系統。本電路架構採用分切合整數位控制進行電流追蹤和直流側穩壓及模組電容穩壓。此控制法考量電感值變化和市電諧波的影響，可以實現快速電流追蹤和有效降低輸出電流失真。基於能量守恆定律，決定每相電路中的直流電流和交流電流。採用電荷守恆和分切合整控制技術，達到電路中直流側電容穩壓和平衡及模組電容電壓的穩壓。為了降低輸出電流之連波，本論文對於模組電容穩壓調節因子進行討論。在本論文中，首先介紹多階層模組化雙向轉換器之電路架構，接下來推導電流追蹤和直流側電容穩壓及模組電容穩壓之控製法則。然後是討論轉換器中電路設計和程式流程圖設計。最後，論文將呈現54kw之模擬結果和20kw之實作結果以驗證轉換器之工作原理和控制方法。
關鍵詞：分切合整數位控制、多階層模組化轉換器、電容穩壓。

This paper presents a division-summation (D-Σ) digital control based modular multilevel converter. Modular multilevel converters (MMC) have been applied to static synchronous compensators, high-voltage direct-current transmission, wind/solar power generation and battery storage systems. The D-Σ digital control is adopted to track current reference, balance dc-bus capacitor voltage and regulate cell capacitor voltage. The adopted D-Σ digital control can accommodate wide filter inductance variation and take care of source voltage harmonics to achieve fast tracking response and low-distortion output current for the applications of active and reactive power injection and rectification with power factor correction. Simulated and experimental results obtained from the MMC have verified the analysis and discussion.
