Calculation of the Core Loss of High-Frequency High-Voltage Transformer Considering the Influence of Temperature

In this paper, a finite element analysis (FEA) method based on complex permeability is proposed to analyze the eddy current loss and hysteresis loss of the ultra-thin strip wound magnetic core, which is used in high-frequency highvoltage (HFHV) transformers. The coefficients of the complex permeability are expressed as temperature equations to simulate the influence of temperature on the core loss...
