Soft-Switched Three-Port DC-DC Converter With Simple Auxiliary Circuit

In this paper, a new high efficiency soft-switching non-isolated three-port converter (TPC) is proposed. the conventional TPC, three switches are required to process power in different directions between inputs and output. Providing condition for all using low number of auxiliary components challenging task. TPC topology modified by changing its structure adding simple circuit such that operate under operating modes. To reduce volume converter, magnetic integrated coupled inductor cell. various modes presented, design considerations discussed. Finally, prototype 200 W, 100 V implemented laboratory, theoretical analysis validated experimental results.
