Converter solution designed to increase power density

03-11-2021 | Premo | Automotive Technologies

PREMO has released the new 11kW 3DPower solution, a full bridge LLC transformer 150µH + resonant choke 25µH merged in one single unit. This innovation offers up to 40-50% reduction in volume compared with current discrete industrial solutions for the same power management.

Most of the power converters in the market have a transformer, resonant choke and output choke. Every component has its own design, core, winding and thermal dissipation solution.

It is claimed to be the first product to integrate two magnetics components that share the same core and feature two orthogonal magnetic fields at all points within the core.

The device is offered with an aluminium heatsink that acts as a direct thermal interface to the cold plate. It is a cost-saving solution also available with 7kW. The company is developing the 22kW solution. Designs can be fully customised according to customer specifications.

The series meets the AEC-Q200 and other more restrictive customer automotive supplier standards. This greener solution has been fully tested in the company's laboratory under real operational conditions.
