My capacitor is giving off a discharge when the output gets shorted.

How would I calculate the fuse value when output gets short in abnormal conditions?

 

I'm afraid I don't understand. Do you have any image you can share? Are you working with a simulator of some kind?

 

You would need to specify a switch model to make the simulation run.


Short circuit current and current waveform depend on capacitor ESR. This is fairly simple to simulate if you know the parameters.

 

What are your parameters?

 

If anyone could share the suddent current vs. time calculation, that would be helpful. The fuse rating is only for the +27V supple denoted by +27V_CGL

 

Short circuit current and current waveform depend on capacitor ESR. Short resistance, circuit series elements.

If you could share the parameters, it may be easier to help.

 

Have you thought about constructing a quick cap discharge tool? You only need a few parts.

 

^That is smart. I just purchased mine from Amazon ... I think ... and its become a good part of my bench at home.

 

I've done the same. We'll see how it goes.
