本論文主要在於探討三相調變器中波寬調變器的諧波消除技術與即時總諧波最佳化等方面的問題。對於傳統諧波消除規劃技術方面，經由加入三次諧波的規劃以改善其總諧波失真的研究，證實加入三次諧波的規劃方式在高功率、低切換次數的應用可以得到減少總諧波失真的功效。
在即時計算的調變器方面，本論文提出一種同時具有切換損失最小化、節省計算時間而且實現容易的即時諧波消除空間向量調變技術(harmonic elimination universal space vector modulation - HEUSVM)。經由空向量的適當配置，使得二相調變(two-phase modulation)的鉗位角度對準線電流的峰值範圍，以避免對峰值電流作切換而獲致切換損失最小化的效果。前述HEUSVM的實現乃是應用對稱取樣方式，本文也證實除了極低的切換頻率以外，對稱取樣無論在基本波誤差或者是總諧波失真等特性，與傳統非對稱取樣相似。本論文也進一步結合了前述的HEUSVM與對稱取樣T0=T7 空間向量調變技術，藉著實際調變指標與臨界調變指標相對關係來選用適當的調變技術，而成為一種即時全調變範圍總諧波失真最佳化策略。
有感於開關元件與微處理器的進步日新月異，中小型變頻器的調變技術之改善已不如以往迫切，於是進一步對變頻器之協同運轉作研究，於本論文中對於對稱取樣T0=T7 空間向量調變的並聯運轉作一探討，並且可以獲得良好的諧波失真改善與容量擴增效果。
前述的調變技術之模擬與實驗結果也將於文中提出以供理論之驗證

The main themes of this dissertation are the harmonic elimination and the minimization of total harmonic distortion for three-phase inverter pulse width modulators. First, the injection of third-order harmonics into the programmed "harmonic elimination pulse width modulator" (HEPWM) is presented. A real-time harmonic elimination space vector modulation technique, the "harmonic elimination universal space vector modulation" (HEUSVM) is then proposed. The proposed harmonic elimination space vector modulation technique not only minimizes the switching losses but also reduces the calculation time for the digital gate pulses of the voltage vectors. The real-time optimal space vector modulation strategy, consisted of the HEUSVM and symmetrical sampled T0=T7 SVM, proves minimal total harmonic distortion characteristics in the whole linear modulation range. Finally the parallel operation of the dual space vector modulators is investigated. The simulation and experimental results of the proposed modulation techniques are proposed and confirm the results based on theoretical analysis.
