A buck-boost converter with extended duty-cycle range in the buck voltage region for renewable energy sources [PDF]

open access: yes, 2023
Buck-boost DC-DC converters are useful as DC grid interfaces for renewable energy resources. In the classical buck-boost converter, output voltages smaller than the input voltage (the buck region) are observed for duty cycles between 0 and 0.5.

Air Pollution and the Risk and Progression of Multiple Sclerosis: A Systematic Review and Meta‐Analysis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose Air pollution has been linked to several neurological conditions, including stroke and neurodegenerative diseases. Evidence regarding its association with multiple sclerosis (MS) remains conflicting, limited by small sample sizes. Methods PubMed, Embase, Scopus, and Cochrane controlled register of trials (CENTRAL) were searched on ...

Magnetically Coupled Buck–Boost Bidirectional DC–DC Converter

open access: yesIEEE Transactions on Industrial Electronics, 2021
A new nonisolated bidirectional dc–dc converter with noninverting output and buck–boost operation is proposed and described in this article. The passive components arrangement in the proposed magnetically coupled buck–boost bidirectional dc–dc (MCB 3 ) converter makes it possible to use triple-phase shift (TPS) modulation, originally intended for the ...

A new optimum topology switching DC-to-DC converter [PDF]

open access: yes, 1977
A novel switching dc-to-dc converter is presented, which has the same general conversion property (increase or decrease of the input dc voltage) as does the conventional buck-boost converter, and which offers through its new optimum topology higher ...
