چکیده
Multi-port DC-DC converter has attracted special interest in applications where multiple energy sources are used. In this project, a three-port converter with three active full bridges, two LCC resonant tanks, and a three-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load, and a renewable source such as solar cell. The converter has capabilities of bidirectional power flow in the battery and the load port. The converter has high efficiency due to soft-switching operation in all three bridges. Design procedure for the three-port converter is explained and experimental results are presented.
