A Study on a Compact Single Input Dual Output Non-isolated DC-DC Converter With Low Switching Stresses

摘要

This paper is a study on a single input dual output non-isolated DC-DC converter topology, its design, and its control strategy. This topology has the benefits of low switching stress, reduced passive component sizes and high efficiency. A closed-loop control system has been designed based on a small-signal model derived in order to regulate the output voltages along with the capacitors’ voltage balancing. SPICE based simulation is carried out for analysis. Scope of this converter in the application in grid connected systems with simultaneous battery charging is also analyzed.
