13th February 2019, 11:37would replacing spark gap for a vacuum discharge tube do much to mitigate emi from spark gap tesla coils?0 replies | 77 view(s) -
5th February 2019, 00:01whats the shelf life for teflon dielectric capacitors? these appear to be a decent deal but they are NOS and might be far off their spec ...1 replies | 778 view(s)

31st January 2019, 15:36Lets make this 580v initial, caps should be 35uF instead of the 9.8nF depicted in image and closing the solid state "spark gap" switch at ~200hz or...10 replies | 547 view(s)

31st January 2019, 10:05In either case a spark gap is fundamentally a switch. Those FETs sound as if they were very expensive TO-264 parts or SOT-227 modules unless you...10 replies | 547 view(s)

31st January 2019, 09:41I was referring to those found in spark gap tesla coil arrangements. The capacitors charge until they reach a voltage defined by spark gap length...10 replies | 547 view(s)

28th January 2019, 10:38Which ferrite has the slowest frequency to eddy loss rating?5 replies | 348 view(s)
-
28th January 2019, 09:42The speed was meant in terms of frequency to eddy losses. Silicon steel will not sustain high frequencies without substantial power losses but Im...5 replies | 348 view(s)

27th January 2019, 04:43I thought the same thing would be the case, the only way to make use of it is to have a solid body of any given dielectric material otherwise its of...7 replies | 649 view(s)

22nd January 2019, 23:07Zak28 replied to a thread rectifier protection at high frequency high frequency from high voltage transients in Elementary Electronic QuestionsThe transient in the diagram is parallel but I meant series transients. Only MOVs, TVS diodes or series high voltage schottkies protect the nmos?2 replies | 227 view(s)
