Analytical Dead-Band Compensation for ZCS Modulation Applied to Hybrid Si-SiC Dual Active Bridge

open access: yesIEEE Access, 2020
This paper proposes a triangular modulation with zero current switching (ZCS) for a hybrid Si-SiC isolated bidirectional DC-DC converter (IBDC). Three of the four legs in the IBDC operate at ZCS and use Si IGBTs, while the fourth operates at zero voltage

Constructing Interface‐Enhanced S‐Heterojunctions Via Surface Functionalization Strategies to Improve Photocatalytic Hydrogen Production Efficiency in Inorganic/Organic Composite Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surface in situ growth strategy was employed to fabricate a COF/TiO2 S‐scheme heterojunction with enhanced interfacial forces. This enhanced interfacial heterojunction significantly improved photocatalytic hydrogen production capacity. S‐scheme heterojunctions play a crucial role in enhancing charge‐carrier separation efficiency and redox capability.
