Electro-thermal virtual prototyping of a Rogowski Coil sensor system

Alain Vachoux, Juan Sebastian Rodriguez Estupinan

An electro-thermal model of a Rogowski Coil sensor system is here described. A co-design methodology between VHDL-AMS and Finite Element Analysis (FEA) has been used for modeling the entire system. The proposed modeling strategy uses geometrical FEA to com ...
