To achieve the buck/Strengthen feature, everything is necessary is 2 separate switches so the AC input might be linked to on the list of two Main taps, even though the load is connected to the other, Hence using the principal transformer's primary windings being an autotransformer.
This a few-stage process lowers AC-facet noise noticeably,⁵ so it is possible that there are products which have been developed with the idea that the resulting noise and ripple about the output of such a supply is relatively cleanse, and would get aggravated with the hundreds-of-Hz hash popping out of a modified-sine UPS.
