Transformer Isolated Buck-Boost Converters [PDF]

open access: yesRenewable 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.

A Modified Topology of Two-Switch Buck-Boost Converter

open access: yesIEEE Access, 2017
Two-switch buck-boost (TSBB) is one of the non-isolated dc-to-dc converters that can change its mode from among buck, boost, and buck-boost modes. Changing its mode is possible by controlling gate signals. This paper presents a novel modified topology of
