Take a look at the files I just uploaded to Files/Temp A simple implementation of what I believe is a corrected form of Pascal's thermal expression, Dave Sent: Saturday, March 15, 2025 1:11 PM To:

We would have a MUCH better idea of exactly where to apply them, if YOU would upload YOUR models. Sent: Saturday, March 15, 2025 1:11 PM To: [email protected] Subject: EXTERNAL: Re: [LTspice]

Thanks a lot for all your message. But, excuses me for my ignorance, all theses modification have to be done in the model ? Sorry but I don't know where. Maybe can you upload your files ? Thanks a lot

Oh, I forgot, you don’t need parentheses around emax, either V={1/(1/emax+0.5*(1+tanh((v(tptc)-ts)/c)))} Sent: Saturday, March 15, 2025 12:05 PM To: [email protected] Subject: EXTERNAL: Re:

Maybe some help, Pascal: I got this to compile and “run” without errors, as below: First, to fill in some unknown values: .params emax=10 c=5 ts=2 Made a voltage source to create and set a value

Hello, ? ? It's poorly coded. will take time to examine everything. Yahoo Mail: Search, Organize, Conquer

Hello, thanks a lot for your reply, Ok I understand, it seems logical. But how about the ?

I can tell you that the error messages do not mean that there is a problem with the simulation. For example, a node connected only to a current source, which has infinite impedance, appears? not to

Hello to the community, I'm very interested by the "PTC Thermistors Physical model" found in /g/LTspice/files/z_yahoo/Lib/PTC%20Thermistors/Physical%20model and I have two questions

Use a resistor to set the nominal load and put a current source in parallel. Then use the current source as the input for an AC analysis. Load regulation (and line) varies with frequency and that is

A common way of testing regulators is to use a current source as the load, but a resistor is just as easy. You need to decide what the range of the load current is going to be. Your circuit presently

BTW -- it might not matter -- but it is slightly odd that you used the higher-power BJTs in the low-power part of the circuit, and a lower-power BJT in the high-power part of the circuit.? With JEDEC

I wrote: I meant to write *Bi* -source.? In other words, a B-source with I=<value>.? You can get fancy where the I depends on its voltage, thus turning it into a controllable resistance.? That's

Your uploaded files have very little information. Is the "regulator" the 3-transistor circuit, with R4 being the load at the regulator's output? Can you? describe how you want the load to vary?? Do

Hello ,I am trying to test a voltage regulator by re[lacing a steady resistor with some sort of varying resistor. Given the circuit in the attached Zip file , what kind of "resistor" you reccomend?

Hello to all, I just discovered the discussion. I would be very interested by the SOATherm simulation. I found it crazy that this is almost unusable as there is almost no documentation on it. Does

You're not, by any chance using Linux+Wine, are you? If so, try ctrl-alt-leftclick. Apparently, alt-leftclick is assigned to something else on most Linuxes, even though the alt key alone produces the

Hello, Marcel: At first, it's the ideal in sketch the applied circuitry in s-domain on how to attenuate the surge amplitude. Sometimes, in math domain, possibly solutions will be clear to see, though
