This paper discusses the technical challenges and trade-offs tied to design of medium frequency transformers (MFTs) for medium-voltage (MV) high-power (HP) power electronic applications, namely emerging solid state transformers (SSTs). A detailed analysis ...
This paper discusses the technical challenges and trade-offs tied to design of medium frequency transformers for medium-voltage high-power applications and emerging solid state transformers. A dedicated design optimization algorithm is used to generate the ...
This paper presents comparative evaluation and explores the different technologies suitable for the implementation of the Medium Voltage Direct Current (MVDC) electrical supplies for the marine on-board electrical distribution network. To realize the MVDC ...
The ever increasing penetration of renewable energy systems in the distribution grids will inevitably require profound changes in the grid infrastructure. One emerging direction, the medium voltage dc (MVdc) grids, is the cornerstone of this work. They are ...
In the area of medium voltage DC-DC conversion, LLC Series Resonant Converter (LLC-SRC) presentsitself as an attractive topology for implementation of the DC transformer. Employing Integrated Gate Commutated Thyristor (IGCT) as a switching element one can ...
This paper introduces an isolated reversible DC-DC converter with a particular topology, which benefits from both the NPC (neutral point clamped) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...
The main challenge of medium-frequency transformers is the number of design parameters, constraints and objectives, and the difficulty of handling them on a particular design. This paper presents a novel computer-aided optimal design for MF transformers us ...
