I'm trying to create a +160v and +/- 100v supply that with idle at 2A. The problem I'm having is I can't find capacitors that can handle the ripple currents for the prefilter. I need to order like $200 worth of caps to keep the ripple currents barely within spec. LC and RC filters don't work because without a capacitor before them the DC loss is too great. Is there a sane way to filter at these currents? A few volts of ripple is fine, I just need the caps to not die after a month. Any ideas?
