It is either a circuit very similar to a light dimmer, or possibly just
a
rectifier.

A rectifier would cut the power in half compared to 230 VAC for a constant
resistive load. This is not what you want.

I thought the high powered ones were nothing but diodes? They're only good
for resistive loads, mostly they're made for irons and hair dryers.
