Abstract

Being one of the most important quality parameters of magnetic materials, iron losses, and consequently iron losses measurement, are extensively treated in scientific papers. There are many experimental set-up arrangements and also data processing algorithms proposed in order to improve the accuracy of measurement results. A sample auto-ranging data acquisition technique, implemented using National Instrument support, is presented in this paper. The experimental results obtained with three different A/D converters (12, 10 and 8 bits) are presented and compared with the results obtained by using the classic acquisition and processing algorithm.
