Transient response of an inverter

What are the values for period and pulse width on the vpulse source?  It looks like you are not running a long enough simulation to see the pulses or that you have period and pulse width incorrectly set.

Thanks for pointing out that. I actually forgot to mention the pulse with and period.

It works now.

Hi,

I am trying to plot the ac analysis of a low pass circuit. When I launch ade L and try to go to results->direct plot -> AC magnitude, my result is in this way.

But when I try to plot  AC dB10 or AC dB20 or any other plots, I have to select an output from the schematic, I get a blank window and when i try to run again, I get the same plot as above which is magnitude plot.

Could some one please tell me if  there are any options to configure.

Thank you

What does this have to do with the transient response of an inverter? I have no idea what you've done wrong here because that ought to work - nothing special should need configuring.

Sorry. I forgot to mention about the pulse width and period of the inverter for the transient response of the inverter. So now that is working.

The other circuit is low pass filter and I am trying to see the ac response of low pass filter. I get the default as magnitude response even though I try to plot dB20 response or magnitude and phase even after configuring the refresh button in ADE L

I would like to know if there are any other options to configure

Thanks

Aishwarya,

My point about the transient response of the inverter was that this is an unrelated question to the earlier question. Please read the Forum Guidelines which expressly ask you NOT to append unrelated questions on the end of earlier threads. It's much more likely that your subsequent questions will get ignored if you do this as everything thinks that the original question was answered.

Anyway, this sounds as if it may just be a basic usage issue. If you use Results->Direct Plot->AC db20, or AC phase, or AC magnitude, you need to click on all the nodes you wish to plot on the schematic and then hit "Escape" for it to do the plot. It sounds to me as if you invoked the command, the blank waveform window appeared, you clicked on the node but didn't hit escape.

I suspect the magnitude graph appears after simulation because you've got the out node in your output signals in the ADE window (using Outputs->To be Plotted->Select on Design in ADE). These get plotted as a magnitude always for AC simulations.

Another way of plotting it is to use Results->Direct Plot->Main Form, and then pick "ac" in the analysis section. Pick Voltage as the function, and then whichever modifier you want (e.g. db20). If you click on the "Add To Outputs" checkbox and then click the node on the schematic, it will plot it immediately (no need to hit escape) and the "add to outputs" part will have added an expression into your ADE outputs pane such that it will automatically plot the db20 of the output signal after each simulation without you needing to manually plot.

Andrew.
