The MEGACube 166kW/20kHz Medium-Frequency Transformer 

ABSTRACT 

High power DC-DC conversion constitutes the key enabling technology for the implementation of solid-statetransformers. Within these high-power DC-DC converters, the Medium Frequency (MF) transformer is one of the main components, as its task is to provide the primary to secondary isolation and the step-up ratio between the different voltage levels. Several options for the construction of this MF transformer have been reported with different considered core materials, winding arrangements, isolation concepts and thermal management, whereby the main realizations will be revised in this paper. Thereafter, the details of a 166kW/20kHz MF transformer will be presented together with the designed test-bench utilized for the continuous testing of the transformer.
