Cost-constrained selection of strand diameter and number in a litz-wire transformer winding.

Cost-constrained selection of strand diameter and number in a litz-wire transformer winding.

Design of litz-wire windings subject to cost constraints is analyzed. An approximation of normalized cost is combined with analysis of proximity effect losses to find combinations of strand number and diameter that optimally trade off cost and loss. The relationship between wire size, normalized cos...
