Hi all,
I have just about completed a design for a -6kV and -3kV output converter. I have current limiting at the front end, but was wondering what are the other schemes I should implement to ensure that I can work safely on this converter with such a high voltage.
I am thinking of having a comparator driving about 3 LED's which work as indicators for different voltage levels for the converter. But I was also thinking maybe I could do something else with this if an overvoltage condition is detected. Is a standard overvoltage protection circuit recommended?
Can anyone recommend a circuit which works well for high voltage and will minimize risk to myself when working with this converter? Power is 600W and currents shouldnt exceed 200mA in secondary. I have been looking at current foldback limiting which is on the secondary side - maybe this would work alongside the main primary side current limit?
