本文对各种型号变压器的交流电阻进行了评估
In this work an evaluation of the AC resistance of various types of transformer’s windings at different frequencies is made. The conductors utilized to build the transformers were the following ones: Foil, Round Magnetic Wire and Litz Wire. Firs of all, it was necessary to assemble all the transformers with the predefined characteristics parameters. This was done in order to be able to analyze the effects of various characteristics. Then an accurate measuring procedure was chosen. After that the theoretical equations were collected with the purpose to compare the theoretical values with the measured ones. The resistance of the foil winding was so low that not all the instruments were able to measure it with enough precision. Comparing the results that have been obtained for the research of different types of conductors, it is suggested that it would be valuable to continue future work utilizing foil windings.
