8. SPICE modeling of ETD49 N67 core from datasheet
Now let’s see how to use the PSpice Model Editor to model a magnetic core if we have data from a datasheet, let’s choose for example the the ETD49 with ferrite N67. The PSpice model of a core can be obtained from the B-H curve of ferrite from the Datasheet and from the geometrical data of the core. PSpice supports two models of magnetic core, the Jiles-Atherton and the Spice Plus model. We’ll approach the modeling of this core with the first method.
Below the list of Jiles-Atherton model parameters:
Open the Model Editor from Start/All Programs/Cadence/Release xy.z/ PSpice Accessories directory
the PSpice Model Editor pops up
from the Model menu select New…
on the New window, write the name of Model Name and as model choose “Magnetic Core”
The Hysteresis Curve window opens
