A New Hysteresis Current Control for Three-phase Inverters Based on Adjacent Voltage Vectors and Time Error
Zare, Firuz & Ledwich, Gerard F. (2007) A New Hysteresis Current Control for Three-phase Inverters Based on Adjacent Voltage Vectors and Time Error. In Power Electronics Specialists Conference, PESC 2007, 17-21 June 2007, Orlando, Florida.
This paper presents a new hysteresis current control technique for a three-phase inverter based on magnitude and time errors. Twelve comparators measure current errors in three phases in such a way to minimise the switching frequency and to provide a better solution to decide adjacent voltage vectors. The advantage of this method is a fast decision and simple control circuit to select the switching states in “ABC” coordinates without prediction of back emf or the derivative of the reference currents. Theoretical analysis and simulations results verify the proposed method.

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
