Research on a topology of single-inductor multiple-output DC-DC converter with high power conversion efficiency

摘要

This paper researches a topology of single-inductor multiple-output DC-DC converter with high power conversion efficiency. Compared with traditional single-inductor multiple-output converters whose output loads are fed only by the energy stored in inductors, the output voltage of this converter is provided by not only the energy stored in inductor but also the energy stored in capacitor. As a result, this converter achieves higher energy conversion efficiency. The circuit description and operation analysis of this converter are displayed and as examples, a single-inductor dual-output and a single-inductor triple-output converter are simulated. The results show that this topology achieves multiple output voltages with high power conversion efficiency.
