Hasan, Also, the range of voltages over which the circuit can give a stabilized output, is not known, unless you know the specifications of that transformer, TR1.  The relays in the circuit select

I might be wrong, but it looks to me like this circuit best provides a voltage boost.  I guess there is one choice for voltage reduction.  So, it might not be a good choice for handling an

Am autotransformer is modelled as several inductors in series, paying attention to the “start” marker. Once the inductors are lined up, write one “K” directive, to define the coupling among

Andy,Thank you to come up some good advice and suggestions. I do believe that if I start drawing  circuit in LTspice, may be others can help me for bug fixing, After a time it will be doable.I saw

The simple answer to your question is this: * Draw it in LTspice. * Press RUN. LTspice is quite capable of simulating electronic circuits such as this.  It is one of the most capable simulators for

Unless I misunderstand, it surprizes me, considering LTspice started in 1991 as SwitcherCAD, clearly oriented towards switching regulators. At least, that's what I undersood.

In general, G (current) sources are preferred over E (voltage) sources.  Current sources tend to result in fewer problems. Have you thought about why?  What would make it work apparently OK with

It takes 3 sources to make a DI/DO amp with CM ref. I tested both E and G sources. Oddly if the 4 feedback resistors are all equal you can swap the output connections and the circuit still works.

There is nothing in the imaged circuit that cannot, in principle, be modelled in LTspice. The most obscure part is transformer TR1. The main winding (taps A … E) is most likely a specific,

A modern stabilized AC supply would use quite different, probably high-frequency switching, techniques, and LTspice is not the right simulator for such circuits. I will try to simulate it in another

Difficulty number 4. I don't know of anything similar, and I would say that it's very old technology. A modern stabilized AC supply would use quite different, probably high-frequency switching,

John, Thank you for the reply. What kind of difficulties you can find?  For example  1. Impossible to make transformers function?2. Relays are Impossible to control?3. The circuit is big enough and

Quite apart from that, it's impossible to simulate that complex circuit without the full specification of every component. This is undoubtedly impracticable.

Why would a ZIP file be unsuitable? Unfortunately, most users of Groups.IO will insist on the common .ZIP compression, only. Dave Sent: Tuesday, December 24, 2024 12:08 PM To:

Zip file is also not suitable.

This being an LTspice group the starting point would be you posting your LTspice files. Not a picture of a schematic. -- http://davesrocketworks.com David Schultz

Dear All,I wanted to build up a voltage stabilizer to study its performance.Kindly help me to simulate the attached circuit file,

You are right, dropping Character Map would be a dumb idea. When I still used Windows years ago, it was a useful tool to me. I used it often to copy/insert non-standard chars into documents. Change

There is no record that you ever uploaded a corrected file, until now. I'm guessing that you uploaded it to a different group and later downloaded it from that other group.  Or maybe you imagined

But I see that the one I had was quite different from the one you uploaded in August. Seems to work, and has the same calling structure (A B W Vpct vs. 1 2 3 Vpct), so def related. Sent: Monday,
