Re: LM324 based automatic voltage stabilizer circuit simulation
|
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, commercial part; but without knowing the expected voltages (or turns ratios) of that winding and taps AND the smaller, isolated one (possibly another 18V, like TR2?), it simply cannot be fully functional.
The three relay drivers on the left side almost beg to be modelled as identical subsections, easily done with the information shown. Same with the High/Low cutout circuit on the right side.
If you can get more details, perhaps someone here can help you!

A modern stabilized AC supply would use quite different, probably high-frequency switching, techniques, and LTspice is not the right simulator for such circuits. >>> In some sense the circuit may not be wrong. This oldest types are cheap rate in market.
I will try to simulate it in another tools.

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 not possible to make sections or subsections? 4. Most of the parts need to be customized.
If possible can you share any similar file to study?
@ Dave, I was missing "?" sign from my last question.

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

Zip file is also not suitable.
