I'm having a problem finding a choke with a small enough current rating for my HV application power supply but which still has a high enough voltage rating. I understand that the choke voltage rating equates to the resistance to arcing of the coil to the frame of the choke.
I thought of putting the choke in the return line but that does not seem to work so well. When I simm it on LTspice it causes a 12 to 16 volt unfiltered voltage on the line connecting the bottom half of the power supply capacitors. Am I correct that the load for that power supply is still connected to regular ground and not the lower end of those capacitors? Sorry if this is a dumb question.
The other alternative that I though about was just floating the frame of these small chokes. As long as there is no danger of fingers or conductive parts in close proximity it seems like I wouldn't need to worry about it. These chokes are close to the range of what the power supply will be, i.e. 300 volt rated choke in a 500 volt circuit. Is this a viable idea? It won't be in a metal chassis, but a wood one.
