Hi Alexander,

it all sounds pure hardware, which job should the 2051 do ?

Also it sounds very awkward to convert a voltage in 3 steps 5V -> 12V -> 36V -> 400V. Why not 5V -> 400V directly ?

And definetively a 12V / 50Hz transformer can not work at 36V / 50 Hz.
Most standard transformers already on tis nominal voltage close to saturation (economize copper and iron).
So on 3 times higher voltage it was saturated completely and act like a short circuit.
