type of smps
well you must be doing radar with that high voltage and low current.
you do supply for TWTA ?
-but anyway, maybe where you work they very secretive and not show you how to do.
but yes, you will get problems with the immense divider ratio, as that divider ratio goes in the transfer function.
do yuo know how to make transfer function for your smps?.....if not then take no fear, as 99.9% of engineers also aint got no clue.
but you can use gain phase analyzer to investigate that loop of yours then you see gain and phase margin.
you could use the beautiful UC3909 high frequency pulse transformer driver to give you a nice piece of isolated feedback.
and i recommend that to you too.
but hey?.....howcome you need isolation???
after all, your highest voltage is on the output........
and also, for military equipment, do they really care about domestic standards?
Anyway, happy wave tubing..........
