    Understanding Core Loss Measurement

    Hello folks, I'm looking for a way to measure core loss in RF transformers & inductors. I ran across this PhD dissertation: https://vtechworks.lib.vt.edu/bitstream/handle/10919/19296/Mu_M_D_2013.pdf which looks thorough and practical, but I'm having trouble understanding some of it. I've...

    How to calculate inductor flux density?

    There are two ways to approach calculating B: by inductor voltage E or by current I. The voltage formula is B = E / (k * Ae * N * f) and the current formula involves calculating H = (N * I) / (path length) and determining B from H * mu or a material hysteresis curve. The problem is these often...
