This happens to be common even in the cheapest UPSes mainly because it will take benefit of elements presently incorporated. The primary fifty/sixty Hz transformer applied to convert between line voltage and battery voltage demands to provide two a little bit unique turns ratios: One particular to transform the battery output voltage (commonly a several of 12 V) to line voltage, in addition to a second just one to convert the road voltage to a rather greater battery charging voltage (for instance a numerous of fourteen V).
For reference, This can be exactly what the unfiltered AC line voltage seems like at the take a look at locale, with voltage learn more vs time to the remaining and a spectrum plot of exactly the same waveform on the correct:
outside of nearly anything the Computer system should really truly take in… so long as your PSU has a decent power performance and isn't larger sized than 800W, of course. (For reference: a contemporary significant-conclude Laptop with an i7-9700K and RTX 2080 Ti need to take in no more than 375 Watts of power in advance of overclocking.)
This is essentially the actual-globe Variation on the idealized waveform shown in fixer1234's reply. The solution to my dilemma higher than, then, is "Yes, they seriously do make UPSes with output excellent that bad."
