Definitions for "Litz Wire"
From the German word "litzendraght", meaning to consist of a number of separate strands that are woven or bunched together such that each strand tends to take all possible positions in the cross section of the wire as a whole. The current through each individually insulated strand is divided equally since this wire design equalizes the flux linkages and reactance of the individual strands. In other words, a litz conductor has lower AC losses than compared to solid wire conductors, which becomes important as operation frequency increases.
A conductor made up of several insulated twisted wires to reduce skin effect and lower radio frequency losses.
Wire woven in a pattern to reduce the " skin effect." For ordinary stranded wire each strand tends to stay the same distance from the wire center. The magnetic field produced by the current in the wire effects the strands differently depending on this distance, causing the skin effect. In Litz wire the strands weave in and out, such that all strands experience almost the same magnetic field, and carry nearly equal current.
