High-Frequency Power Transformers With Foil Windings: Maximum Interleaving and Optimal Design [PDF]

IEEE Transactions on Power Electronics, 2015
Foil conductors and primary and secondary interleaving are normally used to minimize winding losses in high frequency transformers used for high-current power applications. However, winding interleaving complicates the transformer assembly, since taps are required to connect the winding sections, and also complicates the transformer design, since it ...

Analysis of Interleaving Effect for Toroidal Type Transformer Windings

The Transactions of the Korean Institute of Power Electronics, 2015
An analysis of the interleaving effect for the secondary winding distribution of a toroidal transformer is presented in this paper. The equations to calculate the leakage inductance of the toroidal transformer are derived using MMF diagrams for the different secondary winding distributions.
