Misbehaving centre tap transformer model

[PreetamDas17]

Okay I don't know what's the problem. but the attached "No Error" circuit works (which uses a 1P 2S transformer). But the "Error" circuit doesn't work (Which uses a centre tap transformer). In real world a center tap transformer will be more practical in this case. So it will be better if I run a simulation using that.

Hi there,

I run both of the circuits on my computer, they all work fine. I think it's probably due to the simulation settings.

Try to reset to default.

Chen_T,

How long did you run the simulation ? The Error occurs at 0.026s. I've reset the settings to their defaults like you said but it yielded no positive results.

Hi PreetamDas17,

I am using the Multisim 13.0.1 version. When I test your Error.ms13, I do not have any error messages showed up.

But, on your schematic, the sine wave generator seems not working properly. There is no sine wave output at all tested using the scope. I suggest that you replace this with other sine wave configuration to see if you still have the error messages.

For example,

The frequency of the oscillation is f = 1/2πRC

 All of the three capacitors are the same.

R₁ is made very slightly less than R to ensure that oscillations will start when power is applied.

Hope this helps.

That's very strange ! Because I find the sine wave generator (Bubba Oscillator) is working perfectly ! The oscillations starts after 0.250 seconds. The schematic you gave, I'm using it already in my triangle wave generator. I suspect that the generated sine wave using this circuit will be not a perfect sine wave. That's why I used a Bubba Oscillator, because it produces very pecise sine waves.

Hi there,

In your Spreadsheet View, what is the error when you run the simulation? Could you please show it using the Snipping Tool? Is it a transient error or something else? When I run it, there is no error message show up.
