LiWiCalc® - THE high-speed Litz Wire Calculator for power losses

LiWiCalc® is the fastest and most accurate software calculating all dominant power losses on realistic litz wire geometries:
Highly accurate resolution of internal and external proximity as well as skin losses based on the latest scientific method SEEC (Strand-Element-Equivalent-Circuit).
Sophisticated implementation using sparse data structure and vectorized calculations enabling loss calculations for litz wires consisting of several thousand of strands on multiple geometry levels for a wide frequency range.
Highly realistic models of circular or square litz wire cross-sections with copper fill factors greater 50% using an innovative Voronoi-based twisting structure.
Demo version limited to:

  • No allowance to change optional settings.
  • The number of strands is limited to null on null geometry levels.
  • The model size is restricted to a wire length of null mm.

Combination of long-term practical experience and scientifically verified fundamentals published in various journals [1] [2] [3]: LiWiCalc® is a decisive element for the design of chokes, coils, and transformers for the realization of systems with low costs, highest power density and highest individuality.
