3-phase medium frequency transformer for a 100kW 1.2kV 20kHz Dual Active Bridge converter
3-phase medium frequency transformer
for a 100kW 1.2kV 20kHz Dual Active Bridge converter
The article presents a three-phase Medium Frequency Transformer being a part of a 100kW 1.2kV 20kHz Dual Active Bridge DC-DC converter. The transformer design is detailed focusing on winding and core power loss calculation. The high power three-phase MFT prototype is presented. The experimental results include the transformer impedance characteristics, no load test and three-phase DAB full load test waveforms.
