WP2: Computational multi-physical modelling and simulation

We aim at integrating the multi-physical (thermo-electro-magneto-mechanical) and material models developed by Work Package 1 PhD activity, DC1-3, within the advanced high-fidelity and efficient multiscale computational modelling tools of the magnetic components developed by two Doctoral Candidates, DC4 and DC5, ensuring a highly accurate analysis of the eddy-current and iron loss at the component level. DC2 will describe the connections between the power losses of MnZn ferrites and dimensional resonance effects at high frequencies. DC3 will combine the statistical loss theory with micromagnetic simulations to obtain a more accurate physical description of iron losses in different magnetic materials. From the material level, we move progressively to the component and circuit level. Indeed, DC4 will combine (AI- and/or FE-based) reduced-order modelling techniques with multi-physical numerical homogenisation to achieve computationally efficient HF simulation tools for magnetic components; DC5 will use magnetisation curves and losses from WP1 to implement dynamic hysteresis models suitable for accurate iron loss computation in a circuit environment (MATLAB/Simulink). The HF capacitive effects in the windings of magnetic components will be studied by another PhD Candidate, DC6, to enhance the design of the magnetic components and ensure the reliability of the applications in WP3.
