A New DC-DC Converter with Multi Output: Topology and Control Strategies

A. Boora, Arash, Zare, Firuz, Ledwich, Gerard F., & Ghosh, Arindam (2008) A New DC-DC Converter with Multi Output: Topology and Control Strategies. In EPE-PEMC - 13th International Conference on Power Electronics and Motion Control, 1-3 Sep 2008, Poznan, Poland.


This paper presents a new topology based on a Positive Buck-Boost converter with multi output (MOPBB). A single output positive Buck-Boost converter consists of a Buck and Boost converters in cascade which can be controlled against input voltage fluctuation and load changes. In this paper, the steady state and dynamic analyses of the proposed topology are presented along with simulation results. A control algorithm is presented to control output voltages against input voltage fluctuation and step change in load with a purely logic control system that is based on hysteresis current and voltage control. This topology is suitable for a high power multilevel converter with diode-clamped topology where a series of capacitors are required to generate different voltage levels and capacitors voltage control is an important issue in this topology.

Citation counts are 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.
