摘要
本論文為降低交流側諧波污染與改善功因及得到直流側輸出純淨可升降之電壓,提出一高性能三相交直流升降壓型轉換器之研製。該轉換器是將一個三相升壓交流至直流整流器與一直流至直流降壓轉換器整合成一單級AC/DC轉換器,並應用廣義零向量(generalized zero vector, GZV)方法來完成驅動控制電路之控制法則。該轉換器具備以下高性能之特點:在交流側沒有諧波污染的正弦線電流、在直流側能達到可連續調升或調降之純淨直流輸出電壓。更值得一提的是,該轉換器為一單級轉換器架構將可獲得更高的效率並具備雙向電力潮流的能力。在驅動控制電路實現部分,採用德州儀器開發之DSP TMX320F28335晶片做為控制核心,並使用VisSim這套動態系統模擬與即時控制軟體作為開發晶片之工具,可達到控制簡易、即時及降低電路體積等優點,以實現數位化該轉換器之驅動控制電路。最後,藉由VisSim電路模擬與硬體電路實驗結果以驗證所提出轉換器架構之可行性及上述之高性能特點。
ABSTRACT
This thesis main motivation is for reduce AC side harmonic pollution and achieve power factor correction. To receive clean and pure output voltage that can step up/down, to propose a high-performance three-phase AC/DC converter. Based on a generalized zero vector (generalized zero vector, GZV) technique that the converter combines a three-phase boost rectifier with a boostbuck converter to form a single-stage converter of AC to DC. The so called high performance means it is desired to achieve sinusoidal line currents without harmonic pollution, clean DC output voltage, the output voltage can be either stepped up or stepped down continuously, bidirectional power flow capability, integrated single stage converter configuration to achieve better efficiency, power factor correction. VisSim and DSP TMX320F28335 are employed to achieve digital control for power factor correct and feedback control. Finally, by VisSim circuit simulations and experimental results prove the proposed structure to achieve performance as expected.
