Insofar as in applying a power supply to an existing electrical circuit component -- in an instance of if there was not a power supply provided with the component, or if the provided power supply was unavailable -- I would first endeavor to read the specifications of the item, to see what type of current -- perhaps trivially, AC or DC -- and what amperage, and what voltage would be required by the component, so far as would be published by the component's manufacturer.
Offhand, I'm at last outwardly familiar with a "Wall wart" kind of power converter -- as would typically be provided with a laptop -- or an AC-to-DC-over-USB converter, as insofar as charging for mobile electronics from an AC electrical source. Of course, those are all designed for a single-phase household current, in a consumer electrical domain -- as namely for charging and for consistent power of digital electrical devices, each having an internal or detachable battery. Of course, the battery in such a device, itself, would be a type of power source also.
So, as far as electrical sources and their corresponding power adapters, without seeking any too formal reference, offhand:
1) The AC-to-DC power converter in the form of a "Wall wart," so to speak (AC input, DC output)
2) The AC-to-DC power converter provided of an AC-to-USB power adapter (AC input, DC output)
3) Direct household AC electrical (AC input, AC output)
4) Three-phase industrial electrical. (AC input, three phase, AC output, three phase)
5) Rechargeable battery (DC input, DC output)
6) Non-rechargeable battery (DC output)
Perhaps in a bit of a sidebar, as with regards to DC electrical systems: Candidly, I don't imagine there's been as much standardization for DC power inputs, in digital devices -- as much as with regards to so much standardization as developed around household AC systems, regionally, and industrial AC systems, likewise. Perhaps there may ever be some more standards developed for DC power systems, however -- as could be developed in terms of ideal voltage and ideal amperage, such as for powering a heterogeneous range of DC powered devices, prospectively from a grounded household DC line, as might be run in parallel to a grounded household AC line, within a context of a single household?
Perhaps, if one may endeavor to develop any small effort towards a manner of standardization as such, perhaps it could be of some relevance with regards to development of solar electrical systems?
Candidly, I'm not sure of how well such a concept might be adopted in any single industry, however -- so, but perhaps one may endeavor to develop an initial "Proof of concept," a working prototype, sometime, for implementing a household DC line -- perhaps, towards a primarily DC electrical system extending of a solar electrical source, and safely so? Certainly, in a context of a household, a DC electrical current may not need to travel a really long distance -- with an apology, that I know this represents such that one may seek any number of formal references about, if one was to develop a complete thesis about such a concept.
Of course, there are applications for AC inductance, such as of any number of conventional AC devices -- as might typically be in regards to motors and heating elements -- such as may be powered indirectly from a household DC line, if not directly from a household AC line -- and of course, there could be a development of any number of standards as such, as might be addressed firstly around paramount concerns for household safety, in applications, such as insofar as for ensuring a consistent ground, within a prospective, household DC electrical system.
Certainly, there are applications for AC inductance, in household and industrial electrical systems. In regards to industrial domains, certainly, I've read of a transition from DC electrical systems to AC electrical systems, in industry.[1] My not being immediately too familiar with the theoretical qualities of such a transition, but if there may have been, previously, any systems developed for DC power in regards to motors and heating elements, perhaps such old designs could be rennovated somehow, perhaps towards a contemporary application onto solar electrical systems, and broader DC electrical systems? Certainly, with digital systems being so broadly available in the consumer market -- assuming that any single digital system runs on a DC power supply, directly -- then if a DC electrical system could be developed as to support an adequate range of amperage and voltage ratings, among individual digital household devices, though it might seem to represent something of a shift away from conventional household and industrial electrical sources, but perhaps there might ever be an emerging market discovered for such technology.
Insofar as if one may find any applications for DC electrical systems -- such as for a simple feat of driving an electrical motor, for instance, from a DC current, such as for a household air conditioner, in its condenser and motor elements, or a household refrigerator, in a similar regards, or any motorized or heater-type household tools as in a proverbial electrical-powered shop -- but if there may be any similar elements in industrial applications of DC electrical systems, perhaps there may be some similar works developed for household applications.
So, barring any lobbying to the contrary -- candidly -- perhaps there might be a broader application available for DC electrical systems, in household applications, focusing on essentially short-distance household wiring systems and their corresponding safety elements, as well as the solar domain of electrical sources? One might hope it would not seem like a devolution in electrical systems, however -- perhaps, rather towards something of a decentralization, in some regards?
Certainly, I've read of some of the press around households endeavoring to "Go" effectively "Off grid" with solar electrical systems. So, I would certainly not want to be too hasty in any of such a design then, certainly -- though it may seem somehow viable, theoretically, and perhaps none too problematic, electrically, if one may develop a system for a household DC current, and safely so?

Towards Draft 2 of this thesis, Ed. Notes:
- This is not to revisit the War on Currents [Wikipedia] Certainly, the essentially decentralized nature of a solar-electrical system -- considered onto the open market, broadly in a global scale -- may permit for a warless development of a household DC electrical system. One might assume, furthermore, that there would not be any high-voltage lines implemented on Mars, at any time soon.
- The decentralized character of a solar/battery systems may bear some specific note, as in regards to development of solar energy systems for rural applications
- The International Space Station certainly would be using a lot of DC-signal energy also
- Solar, perhaps together with fuel cells.
- How does one ground an electrical system, in outer space?
- Concept, version 2: Parallel-line AC/DC mains system for localized residential application
- Safety concern: DC grounding
- Common ground line for each of AC and DC household mains?
- Technical question: Possible interference to DC mains lines, from AC mains lines?
- Practical concerns:
- Differing DC current and voltage ratings in DC appliances
- Block Diagrams
- Proof of Concept - Case Studies
- Specifications
- Safety
