摘要：

The number and diameter of strands to minimize loss in a litz-wire transformer winding is determined, With fine stranding, the ac resistance factor can be decreased, but de resistance increases as a result of the space occupied by insulation. A power law to model insulation thickness is combined with standard analysis of proximity-effect losses to find the optimal stranding. Suboptimal choices under other constraints are also determined.
