@Andy and @deve, thank you a lot. Now I will sketch the circuit, partially I am trying to find the missing points in this circuit. On Sunday, December 29, 2024 at 03:15:50 PM GMT+1, Andy I via groups.

I’ll update it tomorrow; getting late here. I got answers to most of my issues, so it may be a useful stating point. >>>> Thank you very much, the schematics I showed must have some problem but its su

@kerim, could you kindly share any design or an example where you are trying to show boost-buck actions. Your description looks interesting but need a reference to understand at least. On Thursday, De

Dave Great job 👏 I will look at it. On Thursday, December 26, 2024 at 09:41:03 PM GMT+1, Bell, Dave via groups.io <dave.bell@...> wrote: Please see my recent upload, Autotransformer.zip

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 them; typi

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 over-voltage

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 a

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

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 no

Dear All, I wanted to build up a voltage stabilizer to study its performance. Kindly help me to simulate the attached circuit file, here https://groups.io/g/LTspice/files/Temp/automatic-stabilzer-circ

Andy, It was mid night here so I went away. I think you misunderstood what I meant. Don't change E1, because E1 was OK. Right-click on the E2 symbol -- not on the E2 text, but on the symbol. Find the

That should not happen. If it has the same error, then I think you did not change the Prefix back to E. Maybe you clicked "Cancel" instead of "OK"? (I do that a lot.) >> I changed like right click on

Andy, Thank you for this feedback. Yes, I noticed that problem initially, Now even if I change back to E then it says similar error. What would be values for EM1, EM2, EM3, and EM4? Can we make all 1?

Hello Andy and other experts, I have been playing with a simulation for DC to AC converter attached to the Temp folder. While running the simulation it says " unknown SPICE type device 1....." . I che

Dear Sir Tony, Really you did a splendid job. Your feedback is really appreciable. Thank you.

You are right about the age of the design, but not everything old is irretrievably bad. Assessment of hearing response has moved on a bit over the years, but with no dramatic changes if the hearing lo

-3dB at 200 Hz and 8 kHz with the controls at 'flat' might be a reasonable starting position. Yes, 48 Hz might cause low-frequency overload in some conditions. It depends on the directional response o
