Core Loss Calculator
Core Loss Calculator is a free program that computes the power loss in
ferrite cores for inductors, written by Charles Sullivan, Kapil
Venkatachalam, and Jens Czogalla. Manufacturers publish material
specifications based on a sinusoidal input, but the Core Loss Calculator
is more flexible because it uses an arbitrary piecewise linear input for
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 downloadable
version 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 April 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.

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.
