Hello, first post here - looking for some help designing a circuit. I would call myself a beginner... I can build pretty simple things but have to look a lot up for more complicated designs.
I need help switching 250V on/off fast (sub microsecond). I know that photodiodes can be used as switches, but not quite sure how they actually work as switches. But I have a pretty basic idea of how I think I need to go about it. But not sure how to actually implement it.
What I planned on doing was using an external 5V trigger source to drive the leds.
When LED 1 is on, photodiode 1 sends 250V. When LED 2 is on, photodiode 2 sends 0V. Neither LED will be on at the same time.
The 250V will be coming from a 6kV supply that runs the rest of the set up.
Any help or direction would be appreciated.

Edit: It would be something similar to this...http://patentimages.storage.googleapis.com/pages/US4872057-2.png I have everything else figured out except '21' and '22'. Those are the switches I am referring too. Not sure how to exactly wire those up...
