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.

International Journal of ADVANCED AND APPLIED SCIENCES, 2017 In this paper, a novel buck-boost converter with the voltage gain of 2D - 1/1 - D is proposed. Output voltage is positive and the voltage stresses on the power switches and the diodes are low. Suggested topology is based on conventional boost converter. Proposed converter can provide a large step down voltage conversion ratio.
