Winding Considerations on the High Frequency Transformers

open access: yesEnergy Procedia, 2011
AbstractHigh frequency transformers, used in switching power supplies, carry high amount of current. High frequency effects like skin, proximity and edge effects are discussed in this paper. Multi stranded or litz wires are used for reducing skin effect, but it will be shown that they are not effective in transformer normal winding.
