Re: Terry's DRSSTC - input DC rectifier and filter stuff



Original poster: "colin heath" <colin.heath4@xxxxxxxxxxxx>

hi steve,
Good luck with this project.  I started working with even smaller
coils, and have a DRSSTC running at 550khz ;-)  It throws out some
cute 6-7" streamers at about 50W or so :-).  I will post details to
the TCML when i get the final version built.  But the fact that it
worked well at 550khz suggests that you really *can* build a DRSSTC
driver for just about any (resonably sized) secondary out there, just
have to use the right IGBTs ;-).

what igbts did you use for this steve as i have a secondary kicking around
that frequency and fancy building dr driver for it.
cheers
colin heath
