要約(英語): This paper discusses a design method for a proposed integrated magnetic component for an isolated bidirectional three-port DC-DC converter (TPC). TPC comprises a dual active bridge converter (DAB) and a non-isolated bidirectional DC-DC converter (NBC); each converter is independently controlled with a transformer and a magnetically coupled inductor. To reduce the size of the magnetic components, an integrated magnetic component that can integrate a magnetically coupled inductor and a transformer is implemented. A 750-W magnetically integrated TPC prototype was constructed and tested to validate the operation. The experimental results show that the efficiency of the integrated TPC is above 90% for the entire output power range, which is nearly equal to that of the conventional magnetic component. As a result, the proposed component was 10% smaller than the conventional magnetic components, and the overall size of the integrated TPC was 33% smaller than that of the conventional one.
