Combining a buck-boost topology and Silent Switcher technology brings very low EMI at the highest power-conversion efficiency ...

A non-inverting buck-boost (NIBB) converter is analyzed according to control freedom to implement power modulation. A duty modulation strategy for the non-inverting buck-boost converter is designed ...

A hefty portable power bank is a handy thing to DIY, but one needs to get their hands on a number of matching lithium-ion cells to make it happen. [Chris Doel] points out an easy solution: salvage ...

Abstract: In this letter, a pulse alternation modulation (PAM) for four-level buck/boost (FLBB) converter is proposed. The inherent flaws of the existing modulations are analyzed. The low slope of the ...

This paper presents a new inverter based on three-phase Boost/Buck-boost single-stage inverter. The basic configuration of the new topology and their fundamental principle are firstly introduced, the ...

built in detachable solar panel, 2.) 2.5 - 20V DC input via an internal buck/boost circuit, or 3.) micro USB connector. It can charge from all three sources simultaneously, and of course charge in ...
