| Abstract |
The analysis of a soft-switched dual active bridge 3DC-to-1DC converter, employed in a cascaded-converter-based high-voltage electronic power transformer is presented. The the design of a single-phase transformer, its kVA rating and utilization are derived, due to a phase shift and zero-voltage switching conditions. In the transformer utilization-vs-kVA-rating plane an optimal transformer design point can be found and the design of a single-phase cable-wound transformer with a rated power of 1.66 MW and 1 kHz operating frequency for a 3x16,6kV-DC-to-1x9.6kV-DC conversion is presented. |
