Reply to comment by I_dont_have_a_waifu in How exactly is the "direction" of the flow of power measured in a alternating current system? by Landhund

Yes. I think in their example tho they are thinking about power supplies that rectify and the smooth ac into a useful DC signal. And on practical terms many people consider the ripple negligible and call it a DC power supply.

But I think they are coming from a pretty simplified explanation and then the added nuances don't exactly work with the simplified explanation

You're right, and it's not often that I would bother thinking much about the AC ripple on a power supply like that. I think the only I really gave it much thought was when I was designing rectifiers, and switching converters back in power electronics.

Otherwise I'd just throw a filter on it and call it a day.
