Re: [CAD_CAM_EDM_DRO] EDM Power Supply

Jon,

There are different ways to control the Mosfets. Both a transistor totem
pole or a Mosfet driver will work. The basic idea is to pulse on and off
very fast (you already know that from visiting your website!)

I'll do the best I can at explaining different details, but be aware that I
plan to offer the unit for sale - therefore, eager people may find the
information lacking.

The supply will have both a voltage and current display so you can "see"
what's happening. This is most useful as without this, I would constantly
ask myself, "Is it shorted or is it too far away??" With the display and
some experience, you can drive just by looking at the display.

I hope that helps some. Like I said, I'll try to explain without divulging.
Of course, you could always buy a unit when they're ready and experiment to
your heart's content!
