Increasing AC frequency

Static inverters and motor generators are the usual industrial ways, although 500 Hz is (AFAIK) rather rarer than 400 Hz.

"Simple" and "economical" are slippery words -- compared to a line cord, no, there is no simple and economical way. Compared to the cost and complexity of what you need to power? How should we know, you haven't said!

Thank you, anyone. I'm sorry that you don't understand. Some knowledge of basic electromagnetic theory would go a long way to alleviating your problems in this regard.

Get a 500Hz oscillator, an audio amplifier and an (audio) transformer.

Explain what you really want to do.

Switching supplies are an example of using higher frequencies so that the transformer can be much smaller (because it is handling a higher frequency).

Note that any switching supply converts existing AC to DC, which then powers a power oscillator that feeds the transformer at a higher frequency.

But until you explain what you really want, the solution isn't there.

If you're thinking it would be nice to have a smaller transformer in the power supply, it's already done.

If you hope to get timing off the AC line, but think a higher frequency makes more sense, then you do the timing from some internal standard rather than using the AC line for timing.

Simple:60Hz motor driving a 500 Hz generator. Better:60Hz motor driving a 400 Hz generator, combo to be found in army surplus trade.

Dangit! I was _thinking_ lighter! Really!

(they're sure as heck not cheaper!).

Hello,

the weight of the transformers is important for airplanes and this is much smaller using 400 Hz instead of 50 or 60 Hz. Transformers for the use in airplanes are not cheap.

simple but not economical would be get an AC power supply from California Instruments.
