Magnetic Session II: "Graphene Based Power Magnetics: a New Material for Improved Performance"
Speakers: Claudio Cabeza
In 2019, Premo Group has developed a new material for power windings. The new power magnetics created with this material got increased performance compared with standard ones. Graphene is the key element used in this new innovation.
By applying CVD (Chemical Vapour Deposition) of carbon molecules over copper substrate, graphene layers are created over the surface of the copper. These copper sheets or frames are later used to design the windings of planar power transformers, planar power chokes or copper foil-based power magnetics.
With this new technology, two different approaches can be used as design guidelines for power magnetics:
1. Is possible to design components on similar size as standard ones, but with bigger power handling and thermal dissipation capabilities.
2. The same power level of the standard magnetic can be re-designed to a much smaller size, giving the possibility of component miniaturization on applications where space available or total weight is a critical constrain.
The work presented is patented and under PREMO intellectual property rights. It is the basis for a new high-performance line of power magnetic components under development at PREMO, using graphene-based copper sheet and graphene-based copper foil. This line will include power transformers and power inductors.
