Hysteresis band current control for a single phase Z-source inverter with symmetrical and asymmetrical Z-network
Zare, Firuz & Adabi Firouzjaee, Jafar (2007) Hysteresis band current control for a single phase Z-source inverter with symmetrical and asymmetrical Z-network. In Power Conversion Conference - Nagoya, 2007. PCC '07, 2-5 April 2007, Nagoya, Japan.
A Z-source Inverter has been proposed as a new topology in recent years. In this inverter an impedance network is placed between an inverter and a power source which provides both voltage buck and boost capabilities. This paper presents a unipolar hysteresis band current control method for a single phase Z-source inverter with symmetrical and asymmetrical Z-network configuration. The obtainable output current of this method in magnitude is higher than the hysteresis current control used in a traditional inverter. This paper also analyses the performance of the proposed control method under input dc voltage fluctuation and load current transient. Theoretical analysis and MATLAB simulations have been performed to describe and validate the control method.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
