to all, i just posted a new photo in my album "packrats edm" that shows a schematic to better illustrate what i was describing in my post about TRANSFORMERS...
I think if you will think about it for a minute Ben said that 70V was about right for his version of the EDM machine. Also it is the amount of time that the...
dray, the schematic was left without values on purpose. using the formula in my other post anyone can figure out the values to suit their own transformer....
OK Cary your saying you deal with real EDM's Will you show me one commercial EDM that will allow you to lower the voltage to below 100volts? I have been going...
Cary I do understand you have not take electronics but to back up a few steps your second bridge rectifier in what you call a spark generator has no point. for...
... The important part of this quote is "bridge rectifier in what you call a spark generator has no point" Gee - I wonder if it works like two forward biased...
Sorry Andrew it does not work that way no matter what you wish for. OK the input points on that B2 bridge rectifier are the top corner and the bottom corner...
Hi, I'm very interested in this, unfortunately it seems that this info exchange is quite old. Does anyone has some info about this solution ? which is the...
dray, i know it doesn't happen often but you are the one who is wrong. I AM NOT TRYING TO START A FLAMMING WAR!!!! using a bridge rectifier in this way is a...
... I agree, you can pull all sorts of little tricks with the diodes in a bridge rectifier like you say. One of my favourite wrinkles is flywheel diodes on an...
dray,I AM NOT TRYING TO START A FLAMING WAR!!!!just answering you statements!! by real EDM i meant one's that are based on proven factors, whether home built...
... I have added a PDF of the exact topology, for those who don't understand the jargon. The H bridge is made of 4 switches in the legs of the H, with a load...
... Watton Electronics "Arc Out" - it ONLY outputs 12-15V DC and works fine at removing broken taps, drills and cutting holes in hard materials. Steve...
... D Ray, I am pretty certain I know the way a diode works. I am also pretty certain most people on here know how a diode works. Robert Langlois knew how...
Andrew I was going to try to explain to you how it works but it is obvious you do not know how a bridge rectifier works so we will leave it there I could ask...
As I said apples and oranges I did have to go to yahoo to be able to see you hand drawn diagram. You see we are not building your mosfet system and even then...
It is possible to use the individual diodes in a bridge rectifier. However the diagram shows the anodes and cathodes in the wrong positions. It would not work...
The full wave bridge rectifier just flips the negative side of the AC wave up to give a positive bouncing ball effect to the upper side of zero, the caps then ...
An "H" bridge is typically for driving a DC motor where you need to electronically do forward reverse and shorting of the motor leads together to cause...
... EDM = Electronics Discharge Machining That's what it does - It uses an electrical discharge to remove metal. I removes metal that equals the shape of the...
... Well that was the idea. It wasn't hand-drawn incidentally. ... Are you wilfully missing the point ? ... You really are missing the point aren't you ? The H...
Yes and what is the dielectric fluid that it is using? I agree that for most things edm and plasma are very similar but the are not the same thing. Why dont...
Steve way too long to keep trying to put up with wannabes If you will tell me what part of your supposed "H" bridge YOur name not any one else's. has to do...
... I thought the most appropriate place to upload the scan was Drays own photos folder. The picture is called "Magical Bridge Rectifier" It is part of the...
rob , i didn't pay much attention to the way the cathodes and anodes were drawn, i do know better. the schematic was just to illustrate what i was trying to...
steve i hope you don't mind me answering this for you. dray, as your fond of saying, do you own Ben's book? if so you probably missed the SN754410NE chip in...
... OWWWWW. What the heck is "positive electron" ;-) If a positive electron, or positron, meets an electron, there is a brief and (microscopically) spectacular...
