Hello, i just finished building my sstc, and things are going kinda great, everything works correctly, but to a certain point. after I exceed around 180v the arcs stop and i get nothing. if i go back down in voltage it starts right back up again, but i have to go to zero first. when it stops arcing theres a fairly quiet clicking noise or discharging noise coming from the H-Bridge. Ive tried figuring it out as best i can but i just need someones knowledge. my setup is Kraizer's SSTC II which is basically just steve wards SSTC 5. im feeding 120 fully rectified into a voltage doubler, other then that everythings a exact copy
