New single-input, multiple-output converter topologies: combining singleswitch non-isolated dc-dc converters for single-input multiple-output applications

Abstract

This paper presents a methodology that allows the development of new converter topologies for single-input, multiple-output (SIMO) from different basic configurations of singleinput, single-output dc–dc converters. These typologies have in common the use of only one powerswitching device and they are all non-isolated converters. Sixteen different topologies are highlighted, and their main features are explained. The 16 typologies include nine two-output-type, five threeoutput- type, one four-output-type, and one sixoutput- type dc–dc converter configurations. In addition, an experimental prototype of a three-outputtype configuration with six different output voltages based on a single-ended primary inductance (SEPIC)- Cuk-boost combination converter was developed, and the proposed design methodology for a basic converter combination was experimentally verified.
