Large Capacitor Reforming/Charging w/12v ZVS

Proper leakage testing requires more than what I'm doing here but I plan to handle that on a more sophisticated version in the future. I figure since reforming an old electrolytic capacitor involves simply feeding it voltage to reconstitute the dielectric properly then pretty much any method of safely giving it the necessary DC voltage will work, and this doesn't require a variable transformer with current limiting on the output. This setup is handy for just charging large caps to over 400V at a manageable rate in a portable battery powered build. While this arrangement is not a truly regulated supply I can still vary a set output voltage using the PWM. I need to increase the driving voltage of this one at the buck module in order to charge at over 580V and hopefully I won't lose my smooth ramping. In reality this is not actually needed because it's better to test each capacitor individually, so even a 450V or so max may be a better idea. At 450V even across a series bank the 225V or so across each you're looking for should be close enough to max operating voltage to get a good idea. I plan to use these capacitors on a larger DRSSTC build hopefully using some kind of UD+ driver if I can get one.
