Item type:Publication, Low Voltage DC-Grids with Galvanic Isolation: System Discussion, Efficiency and Performance Comparison to AC - Feeding(VDE Verlag, 2024); ; ; ; Low voltage DC-grids have shown to increase efficiency and performance compared to AC-grids. This paper provides an overview of different feeding configurations for low voltage DC-grids. Their advantages and disadvantages are compared in terms of both efficiency and performance. To prove the considerations, a test machine is evaluated under both DC and AC feeding. It is shown that losses of an exemplary industrial machine are reduced by up to 18.6 % when switching to bidirectional DC feeding with galvanic isolation and by up to 9.6 % without galvanic isolation.journal article42 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Soft Magnetic Components: Functional in Practice Despite Tolerances and Calculation InaccuraciesThis paper is intended to answer the question of how soft magnetic components such as transformers or inductors can function in practical applications. There are indeed high tolerances in the raw material, manufacturing, and calculation of these components. First, the influence of various tolerances on the properties of the components is presented. The discussion of the question follows at the end.journal article43
