120V -> 220v SMPS conversion?

[cuibono]

Sooo, I'm pretty sure the answer is NO!, but can I convert this 120v 60Hz SMPS to 220v 50Hz reasonably easily? The unit is an induction burner, and consumes 1800W. I have two of these and I'd rather not replace them. I have no schematic : P

Some SMPS can handle the voltage range 120Vac-230Vac. That should be marked at the power input.
If this is a pure 120Vac input model, your criterion "reasonably easily" decides the reply.

Most SMPS units use a full wave bridge rectifier on the input. If there is a link on the rectifier, shorting half of it out , that can be removed and employing it as a voltage doubler then if the components filtering the input are rated for 230v AC, it is possible.
Check the label firstly then the schematic.

unfortunately not rated for 220v. I didn't see a bridge rectifier either, so RIP

If I am right then it is not really and SMPS in the sense that others seem to be thinking. I assume Induction Burner means it is a 'hotplate' for cooking. The flat spiral winding seems to indicate as much. Like as not it is probably some sort of resonant mode thing driven directly from the mains and most certainly designed with a specific supply voltage in mind. You would, bare minimum, be looking at replacing power switches and retuning the tank so... not very simple at all.
