Who makes chokes rated at more than 1100 volts?
It will be used in a CLC power supple.

Put the choke in the 0V leg as Eli suggests.

You can use a lower voltage rated choke and bias up the channel frame. This is pretty dangerous though, you have to be careful about mounting.
The potential difference across a choke, in a CLC supply, is considerably less than the rail voltage.
In choke I/P supplies where the voltage rating really comes into play, a way around the rating limit is to place the choke in the ground, instead of the "hot" leg.
Like many other electronic entities, PSUs are inherently differential. We make them single ended, bipolar, or whatever by grounding a specific point.

if 4000V between winding and 2000V between windings and core works, you're in.
Bought a slew of them for a 845 amp (2 each LCLCLC power supply per side, one for the driver, second for the output tube) that I never got around to building, and that (high voltage) was a consideration.
