RESUMO

This work has the purpose of showing an estimate of the modeling of power dissipated in ferromagnetic structures with profoundly saturated parts, through the behavior of the magnetic induction wave form experimented in many parts of the structure when used in saturated reactors. For each one of the analyzed prototypes, the bonding forms of the primary winding, the disposition of those winding in the core and the type of ferromagnetic structure used we taken into account. The resulting values of those estimates were compared with the direct reading values; this proves that this is a satisfactory method. The first prototypes to be studied were the ones with a chain bonding, obtaining the two parts of magnetic losses though estimated modeling and showing the advantages and disadvantages of each one. Later, the same treatment was given to the prototypes of parallel bonding. Lastly, there were the conclusions about the results and comparisons between all the analyzed prototypes as well as suggestions for future works.
