I am in the early stages of designing an adjustable high-voltage DC/DC converter (similar to the EMCO C80 module) and one of the goals is to be able to closely monitor & respond to the output current (e.g. if we sense arcing in the application we want to reduce the output voltage). As a result, I am wondering if instead of using capacitors to filter/buffer the output I might be able to use inductors for this (help maintain stable current).
Is this feasible? Should I be concerned about the
withstanding voltage? Despite being used in a high-voltage supply, there shouldn't be much voltage across the inductor. What are some things I should be keeping in mind?
Update: This supply is used to generate a corona, which will result in some small current (~50uA?). If the current suddenly rises to a higher level that indicates a fault (i.e. arcing or short). My current design uses a full-wave Greinacher/Cockcroft–Walton multiplier. There is a capacitor at the HV output to reduce the ripple, but I am wondering if this possibly also reduces its ability to limit current (capacitor could supply a burst) or if I should care. Are there simpler ways to limit output current than monitoring it (e.g. via shunt + op-amp) and using that as feedback?
