Comment on [discussion] DC (direct current) power network

How does the efficiency and cost of buck converters compare to AC transformers? Seems like the cost and efficiency of the voltage converter should be the prime determinant, rather than specific applications of generation/consumption.
What would a 400A 10kV utility scale DC converter look like?
well, a large part why I asked the question is because I hope that somebody knows more about what buck/boost-converters can do today. I know they work well enough on small scales, but I have no experimental data for them on larger scales.
I assume they would work well, but I’d like that somebody links me to the right datasheet or something.

I think a lot of power blocks rectify the AC and then shift the DC voltage anyway, because transformers are bulky and heavy. This is why power bricks are so much smaller now than they used to be. See the modes section of the Wikipedia page about AC adapters for a longer explanation.
