具零電壓零電流柔切特性之三相六開關整流器

近年來，由於國內外法規標準對電力品質與電流諧波要求逐漸嚴格，故有許多的電力電子切換式電源整流器技術被廣泛應用。其基本型式有相當多種，其中應用於三相供電電源系統中的三相六開關式切換式整流器由於具有較佳的電力品質、較低的電流諧波與較高的可靠度，且適合於高瓦特數的應用，常被使用於通訊工業之設備中。在切換式電源供應器技術中，若採用硬式切換其效率低且易產生較高的電磁干擾。在本論文中，將設計分析一種具有零電壓與零電流切換之柔性切換電路，並結合三相六開關切換式整流器，而實現具有穩定輸出電壓、高效率、高功因與低電磁干擾等特性的新式三相柔切整流器，也進行對實測波形與相關特性的探討。

Since the requirements for both regulation and standard on power quality and current harmonics are more strict in recent years, many switch mode rectifier techniques are widely adopted. There are many different kinds of basic types for switch mode rectifier. Three-phase six-switch topology in three-phase supply power system is often used in the equipment of the communication industry due to the facts that it has better power quality, lower current harmonics, and higher reliability; also, it is suitable for need in high power application. Adopting hard switching in switch mode power supply technology would cause low efficiency and high electromagnetic interference. In this thesis, there is an analysis and design for a soft-switching scheme that contains zero voltage switching and zero current switching. This analysis and the design combined with a three-phase six-switch topology rectifier creates a new three-phase soft-switching rectifier which would have characteristics of stable output voltage, high efficient, high power density, high power factor, and low electromagnetic interference.
