Hello John, The inductance is also a frequency dependent component. Yes, I understand if it'snot air-core, there are many other factors.But that's what we want to achieve, to include the turn-to-turn

Hello Helmut: Thanks so much. I downloaded your model and tried in my circuit model. I think it worked. Of course the expression needs to be refined. So I take it that for inductance, if it's

It goes fast even with n=0.1 for 325V, lower values seem to tak

Mike, The new .ini location follows the Windows' one: /home/<user>/.wine/drive_c/users/<user>/Application Data/. Personally, I run the clean version the way the installer made the launcher, and the

Hello Summer, The formula with FREQ doesn't work. You should use a Laplace function. Below is an example using a G-source. Laplace=1/(0.95*(s/(2*pi*2.5e6))**0.3+0.1) I have uploaded an example. Files

Vlad: Thanks so much for the response. I do want to simulate an AC analysis from 100Hz to 10MHz. The coil is essentially an inductor with a certain value. There's AC resistance too. SO R is increasing

Is there any reason you don't simply install LTspice using Wine? Maybe I'm misunderstanding what you are doing, but whenevr I need to run LTspice in Ubuntu, I simply download the latest executable and

Hello This is the way to do it in LTspice, too, unless you want an .AC analysis. If "freq" is some external source, v(freq), it will work. You may need to add curled braces, though. Good luck, Vlad

I recommend installing and running it from an ext3(4) partition, it will run faster, updates included. Vlad

Here's how to run ltspice on your windows partition from your linux partition. Go here. http://tech.groups.yahoo.com/group/LTspice/files/%20Util//linux/ Get this. HOW-TO-SCAD3-IN-LINUX.zip Includes

Dear LTspice group: I know there must have been many posts on how to build frequency dependent resistor and inductor for a coil antenna. I know in other software, you can just use an expression with

Here's a short (but very realistic) subcircuit for a filament type lamp that has been written for optimum convergence performance in LTspice: * Two Pin Incandescent Lamp Model * * input: Kc =

Hello, Maybe something else is setup wrongly fro LTspice. If you upload your circuit, we might help you. Best regards, Helmut

With the circuit I have though no matter how I position the power supplies I am not getting the expected output so I'm not sure if this part is broken or if I need to position them a certain way and

Good morning Malika, The first thing you ought to do, is create new messages with an appropriate Subject, rather than replying to an unrelated message with a subject that has nothing to do with your

There's a very good lamp model by Helmut in the Files, look for lamp.sub & lamp.asy, you will need to edit the params as required to match your particular lamp. HTH

Hello You may want to try the other Yahoo group, "switchmode", they may have the answers you're looking for. Good luck, Vlad
