Abstract

Transformer coupled multiport DC/DC converter with bidirectional power flow have proven to be an efficient approach to integrate varying sources and storage elements in a sustainable energy generation system. This work presents a Triple Active Bridge converter wherein two ports are wide input range DC links and the third port is optimized for a 48 V battery system. The wide input range DC links are designed for voltages that can be varied between 200 V and 1000 V. To optimize efficiency over the whole operating area, a five winding transformer is developed whose windings can be selected separately to use the optimal transformer turns ratio depending on the three different DC voltages. The converter is capable to transfer power of up to 12 kW with an arbitrary direction of power flow. The construction of the Triple Active Bridge converter is demonstrated. First the required components are designed. Thenceforth the design process is validated by a simulation. Subsequently a schematic of the whole converter is developed. Based on the schematic a PCB Layout is designed, manufactured and assembled. Finally the converter is tested.
