Magnetic Core Loss with Superimposed DC Bias

This dataset aims to provide more insight into magnetic core losses at high frequency (MHz range) with superimposedDC bias in ferrites. The tested MnZn ferrite has a nominal relative permeability of 1500 (PC50) and 800 (PC200), which was tested at frequency from 500 kHz to 3 MHz.The DC bias appears to create a shift in the Steinmetz parameters, in particular the ki and β are affected the most.Higher DC bias creates higher losses gain and higher operating frequency makes the relative losses increase lower.Finally, the Steinmetz Premagnetization Graph (SPG) + iGSE method and Artificial Neural Network (ANN) method are used to create a core losses prediction model.As the result, the maximum error of 20% and 37% were found for SPG and ANN method respectively, while the average errors are 5.4% and 7%.
