Transformer Isolated Buck-Boost Converters [PDF]
Renewable Energy and Sustainable Development, 2016 Of the single-switch dc-to-dc converters, those with the buck-boost voltage transfer function offer most potential for transformer coupling, hence isolation, at the kilowatt level. This paper highlights the limitations of the traditional magnetic coupled, buck-boost topology.
