QCW SSTC More Testing & Toroids

This basically confirms to me now that I can smash the kind of output I was getting from this full bridge as a mains ramped SSTC at 120VAC but be able to do it from something the size of a drill battery or smaller. Had I swung the variac all the way up I'm sure the arcs would have reached out quite a bit further than the max lengths I got from the AC ramps. The difference is that with the mains ramped input I could push a pretty fast BPS without issue. With how long the arcs would seem to be from maybe 250VDC input it's not a big deal to have to wait for them via a charging circuit or cheap inverter like I'm using. I did end up killing half the bridge running it mains ramped a while back at max variac output but I can't remember if I ever found out the cause. I just added the missing IGBT's and started testing it with this setup so no telling if it will die again when I push the variac to the max. That would suck since I'd like to run at least 200V ramps. When I look at the buck output on the scope I already see the peak voltage begin to sag quite a bit when upping the on time. I will likely need to double my bus capacitance on the buck converter to push really long on times that don't diminish the arc lengths a lot, but just beefing up the LC filter more might also help a lot. If I were to imagine this setup running at about 200VDC on bus and it was also dual resonant, the arcs seem like they would be pretty close to real QCW territory so long as I had a big enough main reservoir capacitance to push the real thick arcs. I'm going to grab a bunch of 60N65's when I can and then make a QCW DRSSTC, but regular SSTC's buck ramped seem like they can be pretty awesome which is why I'm building a second smaller QCW when my other arduino shows up.
