Post Subject: Single ended First Watt F5Posted by cv on: 12/10/2009

Hi Romy,
On my to-do list is a single ended version of the F5... essentially just the upper or lower half of the schematic, with a load resistor to opposite power rail (or perhaps a low DCR SE transformer) replacing the complementary portion.

Alas it's quite far down the list of stuff at the moment, but I suspect that with battery supply and very careful, possibly 3d layout, it could be something quite special. I wanted to source the semisouth SiC FETs to try but not much cash at the mo....

I also think that a feedback path that short and direct is nothing to fear; even have Vishay Z foils to try in that position... eventually...

If you fancy trying a version with n channel JFET and the recommended Fairchild P-mosfet, I can mail you a couple of each to play with.

cheers
