Advanced Materials, EarlyView.In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

An Evaluation Circuit for DC-Link Capacitors used in a Single-Phase PWM Inverter [PDF]
High-power conversion systems are based not only on three-phase inverters but also on single-phase inverters because modular multilevel cascade converters (MMCC) consist of half- or full-bridge single-phase converters.
