Tariel Kapanadze claims he's built a OU device that can drive 5kW.

In resonance mode, voltage is stepped up via resonant rise, so in resonance mode, a magnifier is not much different than a 2-coil device. ... No, it would Fri, 05 Jun 2009 06:27:43 GMT William Beaty http://tech.groups.yahoo.com/group/tesla-experimental/message/50 http://tech.groups.yahoo.com/group/tesla-experimental/message/50 ... The "Non coil" rule is there to keep Pupman stuff on Pupman. This is really a science list, not an engineering list. If your goal is to build Fri, 05 Jun 2009 05:30:39 GMT Fred Huff http://tech.groups.yahoo.com/group/tesla-experimental/message/49 http://tech.groups.yahoo.com/group/tesla-experimental/message/49 ... Fred, If a large slow pulse was to create some effect, I doubt it would be anything us mortal people could cook up in our sheds. I have a lot of Tesla's Thu, 04 Jun 2009 17:33:38 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/48 http://tech.groups.yahoo.com/group/tesla-experimental/message/48 In a way its just like having a large zener across the IGBT to clamp to 1KV. It just seems a little "hit and miss" to me. I did talk to Terry a while ago Thu, 04 Jun 2009 15:37:12 GMT Bert Hickman http://tech.groups.yahoo.com/group/tesla-experimental/message/47 http://tech.groups.yahoo.com/group/tesla-experimental/message/47 ... Yes ... Worst case, the slower device would indeed see 100V. If it is only rated for 50V it will likely fail, followed in short order by the remaining Thu, 04 Jun 2009 14:35:14 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/46 http://tech.groups.yahoo.com/group/tesla-experimental/message/46 I've never exactly understood this.. though if you link to SCR's in series (or mosfets), and they do not switch at exactly the same rates, then would this Thu, 04 Jun 2009 13:45:10 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/45 http://tech.groups.yahoo.com/group/tesla-experimental/message/45 I have a common problem with my design here. For example, I would presume a high current pulse is better. However in order to obtain a high current pulse, it Wed, 03 Jun 2009 21:57:08 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/44 http://tech.groups.yahoo.com/group/tesla-experimental/message/44 Fred, If a large slow pulse was to create some effect, I doubt it would be anything us mortal people could cook up in our sheds.

There is a lot of good information out there but it's all jumbled with wacky Tue, 02 Jun 2009 07:42:37 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/42 http://tech.groups.yahoo.com/group/tesla-experimental/message/42 Bill, Thanks for that info, I did not even know about the cone coils operating like that. The magnifier really confuses me. I can understand the driver section Tue, 02 Jun 2009 01:29:11 GMT William Beaty http://tech.groups.yahoo.com/group/tesla-experimental/message/41 http://tech.groups.yahoo.com/group/tesla-experimental/message/41 ... This mode of operation seems to crop up in Tesla's stuff, but I've never seen it discussed outright (or discussed by coilers, ever. It seems to be a Mon, 01 Jun 2009 20:27:45 GMT Chris Swinson http://tech.groups.yahoo.com/group/tesla-experimental/message/40 http://tech.groups.yahoo.com/group/tesla-experimental/message/40 Hi Fred, thanks for the reply, and the link, it looks like something I read a while ago, but will read it again.. what I was told sounds similar, to ramp up a Mon, 01 Jun 2009 19:58:53 GMT Fred Huff http://tech.groups.yahoo.com/group/tesla-experimental/message/39 http://tech.groups.yahoo.com/group/tesla-experimental/message/39 OK Chris, If I get this right you are simply trying to create a very short pulse of high voltage output from a low voltage source. I will dispense with why
