Abstract :
The battery charger and the dc-dc converter can be combined in a single unit with the three-port converter topology. In the three-port converter, one port is idling, while the other two are operating actively. To block power flowing into an idling port, a virtual isolation scheme is proposed. It is also illustrated by a phase analysis. Effectiveness of the proposed isolation scheme is verified by simulation and experimental results.
