Modulation of Local Environment for Selective Bicarbonate Conversion to Multi‐Carbon Products
Advanced Energy Materials, EarlyView.Highly porous Cu electrode partially coated with an ionomer/carbon composite enables efficient conversion of bicarbonate to multi‐carbon products. By regulating the local reaction microenvironment, this strategy overcomes selectivity and reaction‐rate limitations, achieving Faradaic efficiencies of 43% for ethylene and 60% for total multi‐carbon ...

LLC resonant converter modelling
, 2014 Many of today's power converters use pulse-width modulation(PWM) techniques to regulate the circulating currents and voltages. A significant problem with most dc-dc converters is the increased power loss during switching. These devices typically operate in hard-switching mode which results in switching losses.

Digitally Implemented Charge Control for LLC Resonant Converters
IEEE Transactions on Industrial Electronics, 2017 This paper proposes a digitally implemented charge control for LLC resonant converters. By analyzing the small-signal characteristics of the resonant capacitor, it is revealed that the resonant capacitor has exactly the same functionality as a resettable integrator in the charge control for a PWM converter.
