First, I don't need a variable oscillator, I need an oscillator that I can to the frequency (with components) to a specific value somewhere in that range (10k-750kHz). I'll be using the voltage right out of the wall (~110V), and I'll be rectifying it to DC before running it through the oscillator. I shouldn't be pulling very many amps (~100mA) and it will be supplying power on the other end at about 13 watts.
Right now, I'm somewhat stuck because I need to use such a 'high' voltage. I've thought about using something like a colpitts oscillator with components rated for that voltage. This is for a 'wireless' power transmission using an air cored transformer with the coils at about 1.5 inches away from each other.
I figured I'd ask in the RF design section because of the oscillator, hope I'm not wrong, as I'm also new here.
Thanks for the help,
Eric
