Design and Experimental Verification of a DAB Medium Frequency Transformer for a 6.6kV/200V Solid State Transformer

The optimal design and experimental verification of a medium frequency transformer as key element in a 6.6kV/200V modular solid state transformer is reported. The optimization algorithm is based on brute-force approach, which explore the complete design space by parametric sweeping. A 15kVA 20kHz Transformer has been built based on the outputs of the proposed optimal design algorithm and the experimental verification been performed.
