Re: -- EDM power supply -- two paths

Carlos,

I feel I am still a bit green to confirm your suggested input/outputs
but they look pretty good to me.

To All,

I spent a little time searching through Patents and there are some
quite interesting ones on all manner of EDM power supplys. A lot of
them are really just tweaks on the basic idea of pulsing

Here is the site I searched:

http://ep.espacenet.com/

And here are some patent numbers of interest:

US3943321 - Probably one of the first on pulse type supplies
US5276302 - Adjusting the gap using average current
US4617443 - A pulse generator
US4503309 - Good stuff on variable pulses
US4453069 - More pulse supply stuff
US4441005 - Ditto
US4335436 - micro processor controlled EDM
US4090961 - Efficiency monitoring
US4005303 - Detection of undesirable conditions
US3997753 - Gap checking method

Just enter the number into the second search window, click on the
link and the abstract will be loaded. Then use the buttons at the
top to view descriptions and drawings. There is normally several
drawings click next to scroll through.

Cheers,

Graham
