I wanted to share this opinion on Hackaday about a topic that is the usefulness of a something that has become ubiquitous relatively fast.
This techonolgyy has a lot of potential, what do you think?

_ It wants 3.3V, or 5V, or 12V, or 48V, or 18.7V,
Exactly
That’s why if you had a 110VDC supply at the wall, you do a simple PWM step-down to the required voltage in every device.
LOADS cheaper/efficient than any USB-C PD circuit…
Saves on transformers, saves on dozens of USB PD wall outlets, saves on communication needed to communicate the PD required between each device and every USB PD wall outlet.
Much cheaper. More efficient.
If only the wall was 100VDC instead of AC
Why would 100VDC help over AC? You lose very little by rectifying AC.
And again, these aren’t the high draw items in the house. Stuff with motors are, like air con and refrigerators. Those are better left on AC. Why bother when the gains are small?

No. Trend is they are all showing up with frequency drives. Of which those inverters are rectifying to DC before making their own AC.
Efficiency gains are massive of a frequency drive , hence why they are doing it.
Would be even better if they could drop the first rectifying circuit and just use the inverter portion only.
You lose very little by rectifying AC
You lose a lot actually in all the small cheap rectifiers that are in every device in the house.
Where a single purpose designed FET rectifier that is built for efficiency at the breaker would be drastically better.
