Research project on innovative magnetic materials
Efficiency enhancement of charging components by nanocrystalline magnetic materials with niobium.
Research questions on the use of magnetic materials
This research project provided answers to the most important questions regarding the use of alternative magnetic materials:
- What are the advantages of nanocrystalline soft magnetic materials in power electronics?
- What challenges and potentials exist specifically in the application in On-Board Chargers for vehicles in the commercial and industrial sector?
- How readily available is the material on the international market and how important is it to compare and test components from different suppliers?
- Can components based on NSMM materials have an advantage in terms of total cost of ownership?
The innolectric project team was able to answer all these questions as part of a study. In this the soft magnetic nanocrystalline material was compared in detail with ferrite-based cores in terms of thermal behavior, size, cost and efficiency. All analyses, results and experience gained can be found in detail in the white paper.
Functional properties tested in the system architecture
The innovative soft magnetic core material with niobium was tested in direct application in an innolectric on-board charger. In order to achieve the best possible results, the functional properties, thermal behavior and electromagnetic interference behavior were tested directly in an existing system architecture.
Impressive results in direct comparison
The use of nanocrystalline material compared to ferrite-based magnet materials enables significant mechanical improvements without any loss in efficiency and electromagnetic filter performance
- Reduction of the magnetic core volume by more than 60 %
- Reduction in weight of the component by over 70 %
A comparison of different suppliers is worthwhile both functionally and economically. The positive influence of the alternative magnet materials on the total cost of ownership clearly compensates for the slightly higher acquisition costs.
With the help of the knowledge gained, innolectric is now in a position to make targeted use of the advantages of using nanocrystalline soft magnetic materials in future designs and thus generate decisive added value for the products.
Multiple advantages through the use of NCMM cores
“Whether on land or water – our customers today already cover a very wide range of very different vehicles and fields of application. We want to offer them a product that provides great added value across its many features. We are very pleased to have gained a partner with a large network in CBMM, with whom we can take our technology another decisive step forward. We are excited to see what new ways of optimization the new magnetic materials will enable, first in our laboratory and later in the field,” says the project manager at innolectric.
