How do I create this?

Question

Here is what I need in the end:

83.5 kilohertz or any odd multiple of 83.5 kilohertz, aka 167 kilohertz, etc. It needs to switch between + and -, not on and off, etc.
3000v

I have thought of several ideas. One would be having a signal generator that sets the frequency, then stepping that up. My concern is, though, that most types of transformers will change the frequency. Does anyone have any ideas on this?

Another was to produce the voltage, then run it through a computer controlled switch like a spdt switch that would change the polarity in time with the frequency. Could a basic2 stamp be programed to do this?


thanks!

Answer 1

So you need to switch from +3000V to -3000V at 83.5 khz. (And 167 khs is an *even* multiple of 83.5 khz, not an odd multiple)

And wherever did you get the idea that transformers cause a frequency change??

What, *exactly*, means 'produce the voltage'? Have you figured out if you're going to use a high-voltage 60 Hz.transformer, voltage multiplier, what??

And, while we're on the subject of 'what'...... one little thing that's missing is how much *current* this wonder gizmo of yours has to supply to whatever it's driving.

Yes, you could build a high voltage switch that could be driven by a basic stamp or a pic. But you'll have to know how much current it needs to switch.
