How to put oscilator in 50V 500A circuit ?

Thanks, but my info is that relays can't switch that fast.

>>Okay, you might be right.  Have you thought of the very large push-pull inverter?
Oscillators don't get much simpler than that.  You can vary the frequency with the value of the base resistor on the transistors, right?

Thanks for idea, will be looking over it.
At this point I'm only brainstorming the concept, I'm working on something else.
When I'm done with current project, I'll start checking yours suggestions.

why that particular frequency?

I'm trying to apply Tesla switch on car batteries.
Over 800 Hz - strange effects ( so they say ).
Below 500 Hz - not efficient.

use a tone generator and half wave rectification from the output of a headphone jack and you can turn a transistor on and off quite effectively.

but, you will have to double the frequency on half wave to get the desired frequency.
