Hi everybody
Question: I designed a helical inductor 130uH with the range of current from 0ADC to 35ADC I tested that inductor in the workbench and I got the chart how the inductance decreases with the current. With this chart I got the equation of that curve L(uh)= 130-55*((tanh(x/15)^4). I followed the LTspice example " Flux= 1m*thanh(5*x).
I added my equation to the model "Flux=130u -55u*pow(tanh(x/15),4)". Unfortunately the chart I got from LTspice is opposite (curve is going up). Do you have any idea what I missed or did I make something wrong?
I really appreciate you help
Thank you very much and have a wonderful day
