IEC 61000-4-5 Combination Wave Generator Modelling

Why build when you can buy ? Here is one of the best companies ...

HAEFELY/PSURGE8000.asp

I want to simulate and predict, not design, make, wreck and then wonder why...

But thanks for your input.

Oh, sorry, i thought you needed to do the testing.

Anyway...what you are looking at has been done by many others, so, wouldn't the first step be to check the state-of-the-art? Like take apart a Haefely or something similar to see what makes it tick? Just a thought...

Hmm... First buy your Haefely.

i don't know where you are, but one has to buy the IEC too... $1000 apiece generally, but...

Good luck anyway, i am sure you will get lots of help here....

Hiya - the aim of my request is to obtain some circuit values for the network so that I can accurately (as far as is possible in a simulator) predict the effects of the pulse on my energy absorbing networks.

I can look at the absorbed energy, see if the components are adequately rated and whether or not the residual voltage across the devices will exceed the rating of any other components in my system. I can then redesign and simulate again as necessary.

Once I am satisfied that my best endeavours lead to reasonable confidence in my design, I can submit it for test; hopefully to gain a performance accreditation, rather than a sense of disappointment, no idea why the circuit has failed, what to do about it and a (unnecessary) bill for some test equipment that in all probability I will never use again.

Thanks again for your advice.

Apologies if i offended you somehow, not my intention. i am impressed by your goals, and i wish you the very best in your efforts. Alas, i am incapable of helping you here, but am sure there are many experts who will help.

Good luck !
