Will an AC to DC converter work if the input was DC instead of AC?

No Stupid Questions@lemmy.world · 1 year ago

If I were to take a standard AC to DC converter, say a laptop charger, and hook up the input side (which expects 120VAC at 60Hz) to a DC power supply of some sorts, will the electricity still be “converted,” or will it just not work at all? I am clearly very uneducated when it comes to electronics (albeit working on it) so I would very much an ELI5 answer Thanks!

What makes it not work? Shouldn’t the rectifier be happy with almost anything, and anything after the rectifier would be getting the same rectified voltage in either case?
