100 kW DC-DC converter design files

Package “ Medium Frequency Transformers”


The package focusses on the different MFTs designed for the DCDC converter prototype :

  • 180 kVA, 20 kHz, 1.2 kV to 0.6 kV one phase MFT
  • 250 kVA, 20 kHz three phase transformer with modular coupling (Yy, ΔΔ and Δy) and voltage ratio
  • 150 kVA, 20 kHz, 1.2 kV to 1.2 kV three phase transformer with Yy coupling
