Hmm….

So, the HVDC systems us AC transformers to change the voltage at each end, rectify/invert to/from DC at that voltage, etc.

SO, if you want a DC tranmission/distribution/household use system, at each step you invert to AC, use a conventional transformer to change the voltage up or down, then rectify back to DC…

Why would this be better???

If somebody (say a Peer) really wanted to do HVDC, we could generate the DC by re-fitting the Hoover Dam’s powerhouse with Faraday Disks. I suppose said Peer would have a strong position in copper futures, of course…

Peer? No Peers in America. Moguls, senators, and Pork Kings, yes, but no Peers.

Rematog;
Each of those “steps” is lossy, of course. I suppose if the power is cheap enough, you don’t care, though.
