Although I added a load, the new 3-winding model needs to act as LPF even without it, as in the case of the 2-winding one. I am afraid that with an open output, any leakage inductance cannot filter

Sorry, I uploaded it too.

Andy, You are right in all you said. I was somehow shy to upload what I tried doing because their responses were rather ridiculous :( So, I uploaded the schematic with a conventional 3-winding

The 74HC model is missing.

Kerim, But your 3-winding transformer: * is really just a 2-winding transformer but with a center-tapped primary (does that matter?); * is "perfect", with no leakage inductance. If the leakage

More: You don't see any LPF effect because you set K to 1, so there is no leakage inductance. If you set K to say 0.98 you will see a filtering effect.

Present: far too much stuff not relevant to the question of the transformer acting as a low-pass filter. Kerim, if you accept that a two-winding transformer acts as a low-pass filter, you should be

Whoa. I haven't seen of seen BNF for several decades (I think the last I saw it was sgen learnjng Modula-2). DaveD

Hello, Please find the uploaded two schematics in ‘PureSineInv.zip’: [1] Sinewave inverter using a bridge to drive a two-winding linear transformer with no load and whose model include somehow its

That is a "logical OR" separating two optional forms of the command or of a command's parameters. There is a formal mechanism for language specification (whose name I can't remember despite using is

Further to Tony's point above: There is no "Dirac" function in LTSpice, that defines a value at one infinitesimal time. You need a slew-up time, a hold time, and a slew-down time - and three voltage

John asked, " What do you understand 'file spec' to mean? Is it another term for 'filename'? " Almost yes.? That is commonly what "file spec" (or "filespec") means, except that a filespec may include

The clue is in the name: Piece-Wise-Linear. In the waveform viewer, all the points are connected by straight lines. If you want impulses, you will have to create them. But zero width impulses don't

What do you understand 'file spec' to mean? Is it another term for 'filename'? It would be best to have uniform terminology.

Christoph, For time-domain and frequency-domain plots, I think LTspice only connects the dots with lines or curves.? I think there is no other option. I have seen .STEPped simulations where LTspice's

Here is my best guess. I think "analog spiceman" authored that information about the REPEAT ... ENDREPEAT syntax.? Maybe he meant to write it like this: ... PWL REPEAT FOR <n> ( <t1> <v1> ... <tn>
