DF-DRSSTC



Original poster: Terry Fritz <vardin@xxxxxxxxxxxxxxxxxxxxxxx>

Hi,

I have been pretty busy with non Tesla coil things this last month but I did get to run the DF-DRSSTC hard last Sunday.

It worked pretty well! The IGBTs were getting to ~50C and nothing seemed to want to blow up at all. The sparks were a little short at about 2 feet. I think the 60 BPS is hurting it there as well as things not being real well tuned tuned up and such. I also forgot to bring the 5mH line inductor so the firing voltage was about 170VDC rather than ~240VDC. but it seems to work pretty good. DRSSTC are a little odd when figuring out power but it should have been about 380 watts for a Freau number of 1.23. So finding a way to run up to 120BPS is next on the list....

Cheers,

	Terry
