Focus on embedding of power electronics
At present, one of our development focuses is on embedded power electronics in PCBs, so p² Pack embedding. As preparations for mass production get under way for 48 V applications in the automotive sector, we're already working on the next product generation: Embedded "wide band gap" semiconductors for voltages from 400-1,200 V.
The embedding of power electronics allows power densities to be increased and switching losses to be minimised. As a result, ever smaller and more efficient power transformers can be built. The higher efficiency of traction converters means that the electrical range of battery-operated and hybrid vehicles can be increased and cooling effort can be decreased.
If power switches are embedded along with capacitors, power densities can be further improved, which leads to better reliability, too. A further option – the integration of shunts – enables the shifting of current measurement to the inside of the PCB.
High-voltage p² Pack
48 V technology in the automotive sector is one of the largest growth areas. 48 V technology provides a really compact and highly efficient way of supporting the powertrain of mild hybrid vehicles. For use in hybrid or electric vehicles, the operating voltage for the power electronics needs to be further increased.
