Design of Integrated Medium Frequency Transformer (iMFT) for Dual-Active-Bridge (DAB) Based Solid-State-Transformers

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
Dual-Active-Bridge (DAB) converters (DC-DC, AC-DC and AC-AC) are proposed for Solid-State-Transformers (SSTs). Integrated medium frequency transformer (iMFT) provides a compact magnetic solution for isolated DABs, by eliminating the need for additional inter-bridge auxiliary inductor.
