YES, I understand corona, arcing, safety, and Ohm's law...
I am building a high power AC/DC variable power supply: Microwave oven transformers, CW voltage multipliers, flyback transformer, variac... Yes, the bits are potted, and in a massive heat sink with active air-flow. Adequate grounding, etc...
My question is: I would like to use a Raspberry Pi2 as a function generator/oscilloscope. I would use the analog GPIO for the function out, a bitscope for the imaging.
Do I control the upstream supply? The downstream power, or somewhere in between?
What is the best way to use the Pi to generate the signal (sine, square, etc.. vari freq from <1Hz to <1 GHz) then match that signal with the enormous values I get from the supply - a HVLC side, and a HCLV side isolated, and read the output on the scope image
I have a guy who will be coding the function generator, and the scope, so that I have preset wave forms, and display will be one period of the signal. The frequency change will be done via pot, the voltage with a Variac, and the current.. maybe a rheostat.
NOTE: The DC side will have signals: ON/Pulse - the pulse with variable dwell and delay, I thought to drive that with a simple relay.
Using 5vdc to control 0-1MvAC/DC (Not at the same time, and not necessarily that value for each mode)
It runs on 115vAC @ 60Hz. I had considered an LC for the variable freq, but this does nothing for different wave forms, and I do not believe that I can get the frequency range I am looking for with this method.
