Modeling and Finite Elements Analysis of Litz Wire

May 10, 2018

Since the beginning of 2018, Agile Magnetics has made a serious step in confirming its position as a leader in custom original equipment manufacturer (OEM) magnetics with the purchase of specialized FEM 3D software for analysis of electromagnetic and thermal fields.

Аs is well known, winding losses in transformers and inductors increase dramatically with frequency due to eddy-current and proximity effects. One of the most commonly used practical ways to reduce these losses is the use of Litz wire.

Litz Wire: An Ideal Solution for High-Frequency Applications

Aug 3, 2017

Invented toward the end of the 1800s, litz wire changed the way wires are configured. Its name is a shortening of the German word, "litzendraht," which means “woven wire.” A litz wire is composed of individually insulated strands of copper which are braided or otherwise woven together in specialized patterns, as opposed to simply twisting the copper strands together.

 Litz wire is typically used to improve the efficiency of high frequency transformers, inductors, and coils, and carries AC currents at radio frequencies.
