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

EMC Analysis of the Inverting Boost/Buck Converter Topology
Electronics, 2022 This paper describes the electromagnetic compatibility (EMC) analysis of an inverting buck/boost converter. The inverting buck/boost converter differs from other DC/DC converters, such as the noninverting boost or buck converters, in that one inductor terminal is connected to the ground and not to the input or output of the converter, i.e., neither ...
