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

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 ...

To help achieve more precise control of gene therapy, MIT engineers have tuned and applied a control circuit that can keep expression levels within a target range. In human cells, they showed that ...
