Abstract

This paper presents a new multi-output voltage sharing (MOVS) converter. A high voltage application has been considered in this paper, where a novel DC-DC converter is being used as interface in high power renewable energy systems based on diode-clamped multilevel inverter, in which high quality regulated DC voltage is generated for DC link capacitors. Different output voltage sharing can be achieved by a given duty cycle for low and high power applications. Meanwhile, capacitor unbalancing problem in diode-clamped converters could be avoided as the voltage across each capacitor is controlled to the desired voltage level which decreases in complexity of inverter control. The topology easily can be extended to give multiple outputs. In order to verify the proposed topology, steady state and dynamic analysis have been studied. Simulation results are presented to show the operation of the proposed converters.

Citation countsare sourced monthly from Scopus and Web of Science® 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.
