Holcomb Energy Systems:Breakthrough technology to the world

[Dog-One]

I have some improved driver boards online for anyone that may be hampered on the electrical side.

Fully isolated, logic driven at 3.3v or 5v.  MOSFETs (TO-220 style) mount upside down on the back side so the board can be placed on a heat sink with a pair of thermal pads.  Mask removed over the high amperage areas for tinning.  Also on the board are two 5 to 15 volt 1 watt DC2DC converters to ensure gate drive power is isolated--no worries about ground loops from scope probes and such.  This design is intended for using dual power sources or a single bipolar power source in lieu of using full bridge switching.  If you need any RC snubbers, I would suggest attaching them externally, as close to your coils as possible.  Just enough to keep the peak back EMF from smoking your MOSFETs.

The 2EDS8265HXUMA2 driver chip is quite the piece of silicon.  At the time I started designing this board they were available at Mouser, but I see now someone bought a bunch of them up, more are on order.  I'd get some when you can from any supplier that has them.

I like modular stuff and these can be used for anything in addition to driving an HES, though I would like to see someone get a working HES on their bench.

Digikey.com has a lot of those 2EDS8265HXUMA2 in stock.

And this virtual rotating magnetic field of yours can be twisted into a tornado whirlwind ?
With a decrease in diameter and an increase in the angular velocity of rotation ?

Hi kolbacict,

Please show us what you're talking about. Are you able to video the CRT effects in that excited stator?

Got a bit of positive feedback on some product delivered to actual end user !
Will try to find out a bit more detail!
