Magnetic Coupling Branch Based Dual-Input/Output DC–DC Converters With Improved Cross-Regulation and Soft-Switching Operation

This article proposes a simple branch comprised of a coupled inductor, a switch, a diode, and an additional input/output port, which can be employed to substitute the original output/input inductor in two-port dc-dc converters to conveniently derive integrated dual-input/output converters. By connecting the dotted terminals of primary and secondary windings of the coupled inductor together and setting the turns ratio as 1:1, its magnetizing...
