Go to their App note page at http://www.coilcraft.com/appnotes.html and look for the paper titled "Common mode filter inductor analysis" 2) There was a discussion in sci.electronics.cad in 1996 titled "Common Mode Choke Modelling in Pspice?". I was able to retrieve it through the Google newsgroup search at http://www.google.com/grphp?hl=en 3) Also try http://www.highdensitysolutions.com/hdsol/General/TechnicalPapers.html for "Magnetic Components Modeling" Patrick Lawler plaw...@west.net --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

Re: CM Choke simulation
Derek, Yes, do it all the time. As long as you don't get into saturating any cores, you can pretty much use lumped models and none of the nonlinearities associated with core material. Don't forget to include your AC mains cable. It's a trifilar wound transformer. A Belden AC cord looks like a 3 winding transformer with 7uH core. You can also model the LISN and the parasitic capacitance in your test setup. Very educational. Why do you ask? - Robert - -Original Message- From: lfresea...@aol.com To: emc-p...@majordomo.ieee.org Date: Friday, February 15, 2002 1:42 PM Subject: CM Choke simulation Hi all, I'm trying to model a common mode choke in Micro-sim. Has anyone tried this? Failing that, any suggestion on how to model one in Spice, possibly using magnetic models? Thanks in advance.
