A Modified Topology of Two-Switch Buck-Boost Converter
IEEE 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
