Analysis and simulation of a modified single-switch bi-polar multi-output converter

Abstract

This paper presents the analysis, design & simulation of a single-switch, single-input, bi-polar multi-output dc-dc converter. The proposed single-output converter generates positive low and high voltages and additionally generates a negative low voltage as well. No extra hardware is required for the additional negative output. Alternatively another converter with a high positive output voltage and a low negative output voltage is proposed with both outputs independently controllable. The proposed converter has only one switch and hence the efficiency of the system is improved due to low switching losses. Analysis, design and simulation results for the two alternative converters are presented.
