Effects of switching time on output voltages of a multilevel inverter used in high frequency applications
Soltani, Hamid, Zare, Firuz, & Adabi Firouzjaee, Jafar (2007) Effects of switching time on output voltages of a multilevel inverter used in high frequency applications. In Australasian Universities Power Engineering Conference, 2007 (AUPEC 2007), 9-12 December 2007, Perth, Western Australia.
Employing multilevel inverters is a proper solution to reduce harmonic content of output voltage and electromagnetic interference (EMI) in high power electronic applications. In this paper, a new pulse width modulation method for multilevel inverters is proposed in which power devices' on-off switching times have been considered. This method can be surveyed in order to analyze the effect of switching time on harmonic contents of output voltage in high frequency applications when a switching time is not negligible compare to a switching cycle. FFT calculation and analysis of output voltage waveforms and harmonic contents with regard to switching time variation are presented in this paper for a single phase (3, 5)-level inverters used in high voltage and high frequency converters. Mathematical analysis and MATLAB simulation results have been carried out to validate the proposed 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.
