Investigations on an Influence of Selected Factors on Thermal Phenomena in Planar Transformers

K. Górecki, P. Kuryłło (Gdynia Maritime Univ., Poland)

The paper presents the results of investigations illustrating the influence of selected factors on thermal properties of planar transformers. The measuring system used and the tested planar transformers containing different ferrite cores and different winding designs are presented. The internal and mutual thermal resistances of the tested transformers were measured when the windings were supplied with direct current. The temperature values of each winding and core were also measured when the primary winding of the transformers was excited with sinusoidal voltage of frequency varying in a wide range and with adjustable load resistance. The obtained measurement results were discussed and the influence of mutual thermal couplings between the transformer components on their temperature was analysed.
