Modeling and Controlling Strategy of Four-Switch Buck-boost Convertor with Smooth Mode Transitions
The Open Electrical & Electronic Engineering Journal, 2017 Four-switch synchronous buck-boost (FSBB) converter is much suitable for battery management system for its characteristic of wide input voltage range, high efficiency, and positive voltage output. A three mode control scheme with two modulation signals and one carrier can be adopted to achieve the smooth transition among modes.

Advanced Functional Materials, EarlyView.By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.
