110 V 60 Hz to 220 V 50 Hz - of the shelf
« on: June 08, 2018, 04:47:04 pm »
I'm looking for suggestions for a commercial America to Europe converter. For household, not Lab.
It should convert 110 V 60 Hz to 220/240, 50 Hz. It needs to deliver around 20 Watt.
The shape of the output signal isn't very critical. It has to be sinosodialish, but doesn't have to win a beauty contest.
It has to drive a synchronous AC motor so frequency stability at the output side is more important.
Drift over time is not critical, just not a lot of short term frequency drift because the receiving side is a turntable.

I would appreciate if you know of such a product.

You could, off course, tie a 12V converter to a car inverter and call it quits. Probably what's going on inside an all-in-one anyways...

I've seen a few ebay offers that do that. It is an option that I keep open.

Some higher-end UPSs (i.e. Liebert GXT2) have the ability to output a different frequency than the input.  Voltage conversion would have to be done with an external transformer.  But unless you can find a UPS really cheap, the car inverter would probably be a more cost-effective solution.

Out of the box idea;  8)

The power requirements are low, so I am tempted to suggest a class-D audio amplifier, feeding a step up transformer.

The frequency stability and the waveform distortion would be dependent on the source feeding the input.

A VFD would work if you can find one cheap enough.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.
