W. Kolar, M. Baumann, F. Stögerer, F. Schafmeister, H. Ertl, “Novel Three-Phase AC-DC-AC Sparse Matrix Converter, Part I - Derivation, Basic Principle of Operation, Space Vector Modulation, Dimensioning, Part II - Experimental Analysis of the Very Sparse Matrix Converter“, in Proceedings of the 17th IEEE APEC’02, Dallas, USA, Vol. 2, pp. 777 – 791, March 10 – 14, 2002.〕 〔L. Wei, T. A. Lipo, H. Chan, “Matrix Converter Topologies with Reduced Number of Switches“, in Proceedings of the VPEC’02, Blacksburg, USA, pp. 125 – 130, April 14 – 18, 2002.〕〔F.

Ertl, “Novel Three-Phase AC-AC Sparse Matrix Converters“, Transactions Power Electronics, Vol. 22, No. 5, pp. 1649–1661, 2007.〕 Invented in 2001 by Prof Johann W. Kolar〔J. W. Kolar, „Vorrichtung Zur Quasi-Direkten Pulsbreitengesteuerten Energieumformung Zwischen Dreiphasennetzen“, Jul. 27, 2001, Austrian Patent Application (in German), filed〕 , sparse matrix converters avoid the multi step commutation procedure of the conventional matrix converter, improving system reliability in industrial operations. Its principal application is in highly compact integrated AC drives. ==Characteristics〔Java-Animation of the functionality of the Sparse Matrix Converter, iPES (Interactive Power Electronics Seminar) at (www.ipes.ethz.ch )〕== *Quasi-Direct AC-AC conversion with no DC link energy storage elements *Sinusoidal input current in phase with mains voltage *Zero DC link current commutation scheme resulting in lower modulation complexity and very high reliability *Low complexity of power circuit / power modules available *Ultra-Sparse Matrix Converter, does show very low realization effort, in case unidirectional power flow can be accepted (admissible displacement of 30° the input current fundamental and input voltage, as well as for the output voltage fundamental and output current), accordingly, a possible application area would be variable speed PSM drives of low dynamics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sparse matrix converter」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
