Autor: Hugo D. Almaguer, Kaue Jorge Salvador, Sergio H. L. Cabral, Luiz S. Oliveira, Diogo Fernando Harmel
Publikováno v: IEEE Latin America Transactions. 18:1034-1040
This paper presents the performance analysis of a new type of leakage flux collector, designed to act as magnetic shielding in compact power transformers for mobile applications. The analysis was made through 3-D finite-element computer program for m
