Chinese Abstract

本論文之主要目的為發展一具有中性點電壓控制的三階變頻器。本文提出新的脈波寬度調變方法來控制中性點電壓平衡且並與已存在方法做比較。將原本電壓向量所圍繞出的四個區塊劃分成為六個區塊,並只回授上下電容電壓並配合空間向量調變法則,實驗比較結果顯示六個區塊能更有效的降低輸出電壓總諧波失真量。 本文利用Matlab® -Simulink®及所建立之控制理論完成系統模擬,模擬完成後即與實作系統結合,實作部分採用數位訊號處理器(TMS320LF2407A)作為主控核心,並且以三相感應馬達為負載,以電壓空間向量調變(Space Vector Modulation, SVM)技術,藉此控制變頻器12組控制訊號。並利用回授上下電容電壓差與控制因子,來補償中性點電壓偏移的問題,經模擬與實驗結果顯示能有效的控制中性點電壓平衡,驗證出本文控制方法的可行性。

English Abstract

The purpose of this thesis is to develop the control technique for three-level inverter. In this thesis a new pulse-width modulation technique is proposed which provides voltage balance between two DC-link capacitors while reducing the harmonic contents as compared to the existing method. The presented technique is to divide the reference voltage vector into six regions rather than four regions for conventional method. The presented method requires voltage sensor only and can be realized based upon space vector modulation. The presented technique is verified by both simulation and experimental results. The simulation results are derived from Matlab®/Simulink® software. And the experimental results are derived from an induction drive controlled by digital signal processor. It will be shown that the simulation results agree with experimental results very well and confirming the performance of the presented control technique for three-level inverter.
