Hi all I wonder if anyone can provide a design with values for a a variable frequency device. I would like to construct a device that does not rely on voltage variation to vary the frequency over a wide range if possible. Voltage range 100 to 200 AC and this is what I would like to retain with the abilty to vary the frequency. I hope someone out there can help it would be greatly appreciated.

And this has what to do with RE?
