Study of dynamic properties of a multiple-output converter topology suitable for multi-point load applications

This paper presents the dynamic study of a recently proposed single-stage multiple output DC-DC converter topology that achieves high-voltage-low-current on-board power distribution to, and obtains independent voltage regulation at, multi-points loads. The small signal model of the topology is derived to reveal its dynamic properties, and its performance under dynamic conditions is characterized. A prototype converter is built, and simulation and experimental results are presented as the proof-of-concept.
