Hi everybody.
Jay_Diddy_B
Yoy 're writing: 'If I plot Vout versus ESR, I get:'.
This is what I 'm trying to do with the LT SPice file, the '4053 esr meter.asc' you have uploaded.
How can I do this simulation, Vout versus ESR?
Thank you in advance.
pgs and the group,
First, let me welcome pgs to the Forum.
When the thread was started the forum would not allow LTspice files as attachment. So the simulation that you are writing about is included in the zipfile attached to the first message in this thread.
Since the forum rules have changed and now allow .asc files as attachments I have attached the file below.
The LTspice file includes:
.step param ...
This causes LTspice to run the simulation multiple times with different values of the specified parameter. In this case ESR.
.meas ...
This statement causes LTspice to save the average output voltage with a variable name output for each of the steps defined above.
When the simulation is Run, you run the simulation in the normal way, the simulation will run as many times as there are parameter steps. In this case 9 steps.
When all the simulations are finished.
Click View -> SPICE Error Log.
Right Click anywhere in the new window.
Click 'Plot Step'ed .meas data'
And the result will be shown.
Let me know if this helps.
Regards,
