Hi there,
I wanted to build up a voltage stabilizer to study its performance.
I got a simple circuit diagram from online, perhaps someone design it without understanding the LM324 op-amp action.
This has made me curious because I wanted to know it works or not.
Take a look below.
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.
I was trying to simulate this circuit in LTspice, here is the image. Kindly help me to match with the upper one.
Lets calculate the op-amp gain, and fault.
I will be waiting for your response and guidance and comment. Your similar suggestions are appreciable.
NB: DONT comment something that you are not sure about it, I might be silly for you.
