It’s a rube goldberg footgun

That’s the neat part- you don’t!

Pretty sure openmediavault uses it, but that’s the only one I’ve seen
It depends where you measure. If you measure across the inductor, it absolutely goes negative.
The frequency is generally fixed, the duty cycle will vary.
A variable speed drive can be fed with DC. Is the output AC or DC? I know you need a three phase AC motor to wire up to it.
Is audio DC? It doesn’t have a fixed frequency. Amplifiers pulse DC and then remove or ‘block’ the DC offset so speakers see AC.
It seems like people in this thread have a very strict definition of AC being a 60Hz sine wave, and everything else must be DC.
Is a square wave not AC? Current is flowing in and out of an inductor 100k times a second.
Could that 100khz square wave excite a transformer and produce usable current on the secondary? Absolutely it could, and that’s how a bigger SMPS works.
If you’re looking for a “pure DC to pure DC” converter, that’s called a linear regulator and it’s wildly inefficient. They work by varying the conductance of a transistor but are useful for low currents. The extra voltage is converted to heat.
buy dc to dc power converter

And that’s your problem? Do you hold $AAPL

The same counterargument used in every debate about this
I have a 2018 OLED, and the ratio of comments by guests about thinness vs picture quality is 3:1.

It’s the only way to stand out in the store.
They have two divisions and only one is “open”
Non-profit doesn’t mean that no one makes money. But it does mean they pay less taxes. If the C suite is full of funders, you can pay them in bonuses.

I also self host vault warden, it’s pretty straight forward. Like the other person said, it caches locally.

Lose more data, faster!
It volts up under load, maybe the problem is too little voltage at light loads.
