3DPowerTM integrate two magnetic components that share the same core
Manufacturer of inductive components Premo has released the 11kW 3DPowerTM solution, a full bridge LLC transformer 150-microH + resonant choke 25-microH merged in one single unit. It is said to provide up to 40 to 50 per cent reduction in volume compared with current discrete industrial solutions for the same power management.
3DPowerTM is claimed by Premo to be the first product to integrate two magnetic components that share the same core and feature two orthogonal magnetic fields at all points within the core.
This latest solution uses CoolMag, a fully silicon compound compatible with the magnetics. It is fully focused on power magnetic electronics to dissipate the heat from the top of the magnetic to the liquid cooling plate at the bottom It provides a thermal conductivity bigger than 1.7 W/mK and the air is removed by the silicon to improve the heat dissipation.
Once electromagnetic performance is reached, internal and external thermal links become the next focus in the design of these 3D-PowerTM components to ensure heat dissipation.
The 3DP-11KWHVHV comes with aluminium heatsink that acts as a direct thermal interface to the cold plate. 3DPowerTM cost saving solution is also available with 7kW and the company is developing the 22kW solution. Designs can be fully customised according to customer requirements.
The 3DPower 3DP-11KWHVHV series meets the AEC-Q200 (specific automotive quality standard and has been fully tested in Premo’s laboratory.
Premo is based in Spain and is involved in the development, manufacture and sale of electronic components with special focus on power magnetic components and IoT, M2M, VR/AR, connected and electric vehicles.
Its portfolio includes a range of power transformers, inductors and chokes, current sensors, EMC filters, PLC components and RFID antennas (worldwide leader) and AR/ VR motion tracking sensors.
In addition to its range of standard components and off-the-shelf products, Premo tailors solutions to fit customer requirements.
Employing a staff of more than 1,500 and with five design centres, three production sites and sales network, Premo has a global presence in more than 36 countries to meet customers’ requirements.
