本論文旨在針對本實驗室所設計可直接汲取任意再生能源之無槽式管狀線性發電機設計適合的多階轉換器驅控方式。由於線性電機運作時動子為往復運行，動子將不斷的加速與減速，這將使得發電機輸出功率隨動子速度變化而大幅變動，若未經穩壓整流將難以直接使用。在此可將發電機等效模型經由參考軸理論投射至動子參考軸來簡化發電機模型，並以資料擷取系統作為整流器量測與驅控平台，搭配常用的整流器電路架構發展多階轉換器驅控方法。經由不同動子速度下所得的實驗結果，應用於管狀線性發電機之多階轉換器驅控方式提供可用的多階直流電壓輸出。

The objective of this thesis is to design a multilevel converter circuit for driving slotless tubular linear generators (STLG) on retrieving renewable energy application. With the changing speeds and reciprocating directions of the movers, the electric energy generated from the STLG will exhibit large fluctuations and is hard to be used directly. Based on machine modeling and mover reference frame projection, a converter circuit and a data acquisition (DAQ)-based drive control scheme have been developed. From the experimental results, the control scheme implemented on the converter circuit can provide acceptable multilevel dc outputs at various operating modes.
