Combining modern high-power semiconductor devices with constantly improving magnetic materials opens up the possibility to replace bulky low frequency transformers with a new medium voltage medium frequency conversion structures. While there are still chal ...
Medium-voltage (MV) high-power converters are usually realized using high-voltage semiconductors (3.3kV, 4.5kV or 6.5kV) operated with low-switching frequencies in the range of several hundred Hz and under hard-switching conditions. However, for medium-vol ...
The paper describes the design of optimized printed circuit board (PCB) air-core toroids for high-frequency dc-dc converters with strict requirements in terms of volume and noise. The effect of several design parameters on the overall inductor volume, on d ...
Europe is currently making a great effort in order to improve the sustainability and reduce the environmental impact of its energy and transportation systems. A key role on these initiatives is played by efficient generation systems, like cogeneration, and ...
Medium voltage (MV) power electronic transformers (PETs) are nowadays considered, for various industrial applications, as a viable replacement for bulky line-frequency operated transformers. In MV applications modularity in the converter design plays a ver ...
A major change in the electrical transmission and distribution system is taking place in Europe at the moment. The shift from a centralised energy production to a distributed generation profoundly changes the behaviour of the grid. Environmental or social ...
A power electronic transformer converter made of cascaded multiple cells with a medium frequency link can replace the bulky traditional transformer in various applications with several advantages, including reduced size and weight, and energy savings. This ...
In view of the Large Hadrons Collider experiments upgrade, where the inner front-end electronics will require higher supply power, a new power distribution scheme has to be designed. This thesis presents a new and more efficient scheme based on step-down D ...
A highly interesting application field of the Modular Multilevel Converter is the interconnection of the European three-phase 50 Hz industrial grid with the single-phase 16 2/3 Hz railway supply. Contrary to existing technologies, the utilization of a bulk ...
Medium voltage (MV) high power applications are usually realized using high voltage semiconductors (3.3kV and above) operated in hard switching mode with low switching frequencies (several hundreds of Hz). However, for high power DC-DC converters employing ...
