RF Diode
« on: December 14, 2012, 19:44:47 pm »
Has anyone ever tried using an RF diode in the VIC?  Considering the frequencies we're using, would they not be more suited to the circuit?  Could this be what Meyer referred to as a switching diode?

I use to get hi freq ones for around 30euros in italy... i burned lots of them it were 80 amps 1200 wolts...

I've been doing some investigating into fast recovery and very low voltage forward diodes.  It seems to me if we want to have the most voltage available inside the VIC circuit that we want make sure that there's minimal resistance from the other components in the VIC, such as the diodes voltage forward.  Any resistance should exclusively be from the inductors.

Some Schlottky diodes have a Vf as low as 0.2V.  I'm starting to believe that Meyers reference to switching diodes was actually a reference to to these low voltage forward diodes or something similar.

PIN diodes also seem to have interesting properties.

not sure.. maybe just high surge current ability...
