A. Boora, Arash, Zare, Firuz, & Ghosh, Arindam (2010) A new family of multi-output DC-DC converter topologies to supply an asymmetrical four-level diode-clamped inverter. COMPEL : The international journal for computation and mathematics in electrical and electronic engineering. (In Press)
Multi-level diode clamped inverters have the challenge of capacitor voltage balancing when the number of DC-link capacitors is three or more. On the other hand, asymmetrical DC-link voltage sources have been applied to increase the number of voltage levels without increasing the number of switches. An appropriate multi-output DC-DC converter can resolve the problem of capacitor voltage balancing and utilize the asymmetrical DC-link voltages advantages. Furthermore, there is a possibility of operation at high modulation index despite reference voltage magnitude and power factor variations.
A family of multi-output DC-DC converters is presented in this paper. The application of these converters is to convert the output voltage of a PV panel to regulate DC-link voltages of an asymmetrical four-level diode clamped inverter utilized for domestic applications. To verify the versatility of the presented topology, simulations have been directed for different situations and results are presented. Some related experiments have been developed to examine the capabilities of the proposed converters.
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.
