Single-Input Multiple-Output Synchronous DC-DC Buck Converter

This paper proposes a new single-input three-output DC-DC buck converter. The proposed topology has two less switching devices than that of a conventional converter. This reduction in switching devices results in lower cost and a more even distribution of power losses among the switching devices. A comprehensive small signal Modeling and control strategies for the proposed converter will be presented. Simulation and experimental results are presented to validate the theoretical expectations. The simulation is performed using PSIM, and the laboratory experiment is performed with a proof of concept prototype.
