3DPOWERTM
A Tech Disruption in Power Magnetics Integration
Existing magnetics within conventional OBC & DCDC converters merged into one single and compact unit: a Full Bridge LLC Transformer + Resonant Choke.
Why 3DPower™ ?
A greener, space and cost saving solution
SIZE & WEIGHT REDUCTION
2/3 Components in 1
50W/cm3 POWER DENSITY
Maximum power density is achieved by reducing the size and increasing the power dissipation with the latest high thermal conductive materials (CoolMag™).
X3 LESS FERRITE USE
Combining 2 or 3 magnetics components in one special single core.
CUSTOMIZATION
Designs can be fully customized to meet customer requirements

Patented cutting-edge technology
Backed by decades of experience in Automotive
EPO 16002354- EPO 16002348

This patented technology is more than a stand-alone magnetics component. It’s a way to design and develop custom power magnetics components. The physical nature of electromagnetic fields allows the co-existence of multiple magnetic fields into same magnetic material core considering the design maintains ninety degrees orthogonality among the fields (Maxwell Laws).
3DPower™ is the very first technology in the market using this physical design concept applied to Power Electronics.
Tailored to your industry
Innovate your end-applications one step ahead with our 3DPower™ Technology
APPLICATIONS
SECTORS
Boost topology
Integrated and reduced size for high power density boost topologies. Fully optimize component with CoolMag potting drastically reducing the max hotspot temperature.
Resonant LLC DCDC converters
For LLC resonant topologies serial resonant choke is integrated with the transformer in a small and compact solution. All the component is filled with thermal resin CoolMag to ensure the thermal link.
Phase Shifted Full Bridge
For Phase-Shifted Full Bridge converters serial and parallel chokes can be easily integrated with the transformer. This integration reduces the weight and size of the magnetic. All the component is filled with thermal resin CoolMag to ensure the thermal link.
