I've got a plan for a large electroluminescent display. EL panels are typically driven with a sine wave at around 1kHz, and I want to use mains power for this. What's the best way to convert mains power from 60Hz to 1kHz? I don't need a whole lot of current - 500mA RMS should be plenty.
I've been thinking converting to DC, then back to AC again would be the simplest way to do this, but I'm concerned about the efficiency of such a system; is there a better way? I also don't know how I'd produce a clean sine wave (EL is quite picky) at the output.
EDIT: I'm in the US, so this is 120V at 60Hz.
