On a related subject, what do you use for the switch in these surge generators? I have seen electro mechanical switches and I believe some of them use SCRs? Is there a readily available high voltage switch that can do it?
We have a need to test a medical device using a 32 µF cap charged to 5000V for one of the 60601 standards to simulate a defibrillator. We were going to modify an old Haefely P6T.

I am about to build something similar, and would like to know if someone has already experimented with this. thanks, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Fred Townsend Sent: Wednesday, November 04, 2009 10:36 AM To: [email protected] Cc: [email protected]; [email protected] Subject: Re: [PSES] Discharge capacitors Derek : I think Orin offers good advice. You also need to pay attention to your network geometry. i.e. Inductance is your enemy. Two 10 uF caps in parallel are better than one 20 uF. Straight runs of ribbon wire are better than coils of round wire.

They all know what they are doing and have low inductance pulse rated caps capable of multi-kiloamp discharge peaks.

Can anyone share their opinions on manufacturers and/or models that are appropriate. An offline response may be appropriate.
