Tony, Understand the .step and .param are Spice directives but where does the "V1 OUT 0 {Perturb}" go.? Is that the DC value for the V1 supply?? Also do you run this as a transient analysis, DC

Yeah, adjacent key typo… Sent: Thursday, January 02, 2025 9:52 AM To: [email protected] Subject: EXTERNAL: Re: [LTspice] AV Voltage Stabilizer update Dave, I'm just curious - The Subject line is "AV

Hi all, I'm a bit late to this discussion but I came across the? current "TBL" function too and wasn't really sure what it meant and like the initial poster didn't find a satisfactory answer in

Dave, I'm just curious - The Subject line is "AV Voltage Stabilizer update". What is the "AV" about? Is it supposed to be "AC"? Andy

Hi, Hasan, Just getting around to looking at your uploaded circuit. The Relay Driver subcircuit already incorporates all of the external components to the left of each on, the input diodes,

Add a .STEP command, where you step a parameter representing the four voltages.? Then use that parameter to control the voltage source's magnitude. *Note* that Dave's schematic STILL has the mistake

Remember to always include the symbols and models used that did not come with LTspice. Don't think that you do not need to because it is in the latest directory on your computer's drive, or because

More tomorrow, but . . . 1. You need a .param statement to assign a value to “wp”, a wiper position for the pots inside the relay drivers. See below 2. R11 has no assigned value 3. D11, 12, and 13

Dave, Thank you a lot for making such clean simulation circuit.You can remove the transistor switching relay part but perhaps it has been made for getting protection in real case.I understand why you

New update to the modified AC Stabilizer circuit: Fixed the output relay, I believe. Replaced the driver circuit with a NO relay only. Dave Sent: Wednesday, January 01, 2025 5:20 PM To:

Hasan, please see the new file I just uploaded. Cleaned up the three relay driver circuits pn the left side. I'm not sure if the driver in the upper-right will work there; the inputs are different,

Sorry, I realised that I didn't quite get that right - the perturbation is proportional to Vmc. This fixes it: .step param Vmc 0 10 1 .param Perturb mc(1,0.05)+Vmc-1 -- Regards, Tony

If you have never changed your default font size, then you do not need to change it back to the default size. The default font size is in LTspice's Control Panel (settings).? It is the toolbar button

I uploaded "ADC Flash AI1.asc" which has some things fixed. * I removed the short-circuit that was across V2. * I removed the short-circuit that was across Vin. * I changed Vin so that it sweeps over

Not surprisingky, I've never seen that design. ------------------------ DavD KC0WJN ------------------------ [email protected]> wrote:

Thank you @andy to take part here.? 1. LM324 lib is absent ! You may not need an LM324 model.? The LM324 is an op-amp.? You can probably use UniversalOpamp2 which is in LTspice.>>Yes, I can see,

Indeed! Major difference at 28 B. I see why it looked terrible. I’ll see if I can “tolerate” it there… Dave Sent: Wednesday, January 01, 2025 9:54 AM To: [email protected] Subject: EXTERNAL:
