Core Loss Calculator is a free program that computes
the power loss in ferrite cores for inductors. Manufacturers publish
material specifications based on a sinusoidal input, but Core Loss
Calculator is more flexible because it uses your arbitrary piecewise
linear input for flux density.
For more information about the improved equations
used, see related
papers and publications.
What software do I need? How can I run it?
There are two versions of Core Loss Calculator. The web-based
version runs the calculations on our web server. The
is for use with MATLAB
Version 5 or 6, available from Mathworks
for a variety of platforms. The two have similar capabilities, but the
downloadable version allows for a non-limited number of data points.
Update 4/2006: A bug in both the online and downloadable versions has been corrected. A
typographical error in a variable name made the results inaccurate for flux waveforms with
minor loops. The error has been corrected in both the downloadable version and the online version. The file name
of the new version is coreloss1.m. If you are running "coreloss.m", please download the corrected version.
Core Loss Calculator for use with MATLAB software.
The directory the coreloss1.m file is placed in must be on the Matlab
path in order to run it from the Matlab command window. Help and
information about the function is available by typing "help coreloss1"
at the command line.
