Description and Efficiency Comparison of Two 25 kVA DC/AC Isolation Modules

Alfred Rufer, Frédéric Zurkinden, Daniel Siemaszko, Lukas Fleischli, Irma Villar

In the frame of the European project UNIFLEX-PM, two AC/AC converter topologies hove been studied and implemented. Both converters, rated for 25 kVA, are isolated by a medium-frequency power transformer. The first topology is based on a dual active bridge ...

Multichannel DC-DC Converter’s Efficiency Optimisation by variable Number of active Channels

Alfred Rufer, Sylvain Lemofouet-Gatsi, Lukas Fleischli

In the context of energy storage with supercapacitors, the so called round trip efficiency is an important factor that can be strongly affected by the characteristics or performances of the used converter. This paper presents a dedicated DC-DC converter, w ...
