STRUCTURE & IDEAS

NEW - new topics
REWR - needs a major rewrite
INPROC - someone is working on this
DONE - job done!

Hardware

  • NEW Optimal computer configuration for FEM-based simulations

Geometry

  • DONE Importing CAD geometries
  • NEW Parametric geometry setup - let's demonstrate how to use simple geometries and strategies to solve complex cases.
  • NEW Reduction of geometrical complexity - geometry cleanup, use of symmetry.

Calculating Lumped Circuit Values

DR resistance

  • NEW Model for calculation of DC resistance - moderate mesh refinement for coils, 0Hz preferred, focus on conductor temperature, fill factor, and wire terminals.

AC resistance

  • NEW Skin and proximity effect
  • DONE Homogenization of Litz & Stranded
  • NEW Use of symmetry (reference to Geometry)
  • NEW Eddy currents in the core (reference to the Core loss)

Inductance

  • COMBINED Magnetization inductance (excitation sweep) → pay attention to BH curve
  • COMBINED Magnetization inductance (frequency sweep) → pay attention to eddy currents in the core
  • COMBINED Leakage inductance → mesh refinement between windings
  • NEW Useful tips - use of symmetry (a reference to the Geometry) + proper number of turns (e.g. 3/4 turns)
  • DONE Inductance (frequency and excitation sweeps) - Combined topic of Magnetization and Leakage inductance.
