Encapsulated or Potted Coil, what to choose?
An electric coil is made up of two distinct parts: a conductor and a core. Typically, the conductor is solid copper wire wrapped around a metal core. A turn is formed by looping the wire …
Optimal Strand Count in Litz-Wire Transformer
A salient difficulty in designing high-frequency inductors and transformers is eddy-current effects in windings. These effects include skin-effect losses and proximity-effect losses. Both effects can be controlled by using Litz wire—conductors made up of multiple …
