I'm baffled by some of the ludicrous requests I get...
I need to design an isolated power supply with two output channels. The requested output voltage per channel was specified to be adjustable between 0V and 180V with 1V increments, and each channel needs to deliver 500W of power (total power would be 1000W for both channels). Total tolerance should be no more than +/-1V
My first thought was to buy two of these suckers to isolate the circuitry from the mains:

From there I figure the best approach would be to use some form of a PWM step-down circuitry with a PID feedback loop.
Has anyone got any experience with high voltage/high power supplies?
Does a complete solution in form of an IC already exist, or am I going to have to design this by myself? I searched but couldn't find anything with the specifications I need.
Thanks,
