EMC
design > analyse > optimize

To respect the time-to-market requirements and to comply with the product's specifications, the virtual prototyping of EMC phenomena has nowadays to be performed from the early design stages by means of accurate, robust and well-adapted simulation tools, able to interact with each other. Therefore, the CEDRAT solution for EMC is oriented towards the integration and the dialog between three tools: Flux, InCa3D and Portunus. 

CEDRAT simulation software solutions for electromagnetic compatibility

Flux: All 2D and 3D low-frequency electric and magnetic analysis by means of FEM solver

InCa3D: 3D non-magnetic interconnections modelling based on PEEC method

Numerous EMC applications

  • Placement of components on PCBs: decoupling capacitors, common-mode filters, paralleling of power components...
  • Routing of PCB layouts: layers stack-up, tracks shape, planes position...
  • Parasitic behavior of interconnects, of micro-coils for MEMS, of grounding and shielding systems...
  • Conducted and radiated emissions of electronic subsystems: power modules, variable speed drives, inverters, rectifiers...
  • Magnetic effects of electric energy installations on health: low-voltage substations, overhead lines…
