Re: Dan's ultrafast gate drive, schematic?

Hey,

I don't have an exact schematic, but I remember the concept. He was 
basically rectifying the output, and using it as a DC/DC converter, 
and getting the signal from the diode bridge, so the transformer 
supplied both power and signal.

It should be possible to get it to cope with variations in duty 
cycle, with a proper DC blocking capacitor, but it might be tricky to 
get it to work right.

Hi,

there used to be a schematic for an ultrafast transformer coupled
gate drive on Dan McCauleys homepage
(<http://www.easternvoltageresearch.com>http://www.easternvoltageresearch.com) 
that I think he used in some
audio amp SSTC. But now a lot of site sections are "under work" and I
can't find the PDF/schematic for this circuit.
Does someone still have a copy?

I was considering to use it in a high power digital audio amp. And
BTW, maybe someone has the circuit or schematic, /and/ even knows if
it can cope with large duty cycle variations from pulse to pulse, as
needed for audio amp work? :-)

Thanks!
