The review summarizes the progress of emerging 2D manganese-based materials as advanced electrode for EES.
Abstract Metal–organic frameworks (MOFs) are crystalline porous materials with a long‐range ordered structure and excellent specific surface area have found wide range of applications in diverse fields, such as catalysis, energy storage, sensing, biomedicine. However, their poor electrical conductivity chemical stability, low capacity, weak adhesion to substrates greatly limited performance. Doping has emerged unique strategy mitigate the issues. In this review, concept, classification,...
In order to reduce the cost and volume of small-medium power ac-dc light-emitting diode (LED) lighting systems, single-stage LED drivers are often used drive LEDs with constant current. this paper, a isolated high-power factor driver is proposed analyzed in detail, which composed buck-boost correction unit operating discontinuous conduction mode an dc/dc voltage doubler rectifier, two units integrated together by sharing same switch. Very high input achieved since PFC operates almost fixed...
Low-voltage enhancement-mode gallium nitride high electron mobility transistors (eGaN HEMTs) are a kind of promising devices to realize high-efficiency and high-power-density conversion because their fast switching speed, low conduction, losses. Since the reverse conduction loss eGaN HEMTs accounts for large part losses, it is great importance improve traditional analytical model predict loss. In this paper, complete accurate low-voltage presented, which considers effects low-parasitic...
Wide bandgap devices such as gallium nitride (GaN) are being widely used due to their low on-resistance and parasitic parameters that can improve system performance compared Si mosfets. However, these advantages mentioned above sometimes lead unexpected behavior in practical systems, false triggering oscillation. False oscillation may cause overshoot, electromagnetic interference, shoot-through, even device damage, which seriously affects the of system. In this paper, an RC snubber circuit...
Herein, we report the first result of large scale and oxygen vacancy VO
Selective production of <italic>p</italic>-chloroaniline from <italic>p</italic>-chloronitrobenzene without any further hydrogenation products was found feasible by catalytic over the Pt–Fe/AC catalyst.
The hybrid distribution transformer (HDT) achieves a compromise between the low-frequency (LFT) and solid-state (SST). It combines LFT's efficiency reliability with added advantage of partial power controllability via an integrated converter. However, existing research on HDT fault ride-through does not consider coordination relationship its own safe operation constraints, while few studies have considered capacity multiple converters. Therefore, this paper proposes improved hierarchical...
Pristine MOF nanosheets with a highly active metal–sulfur (M–S, M = Co and Ni) region as cathodes for Zn–Co/Ni batteries are successfully prepared through dual substitution strategy of metal ions organic ligands.
Hierarchical Cu/Cu(OH)<sub>2</sub> nanorod arrays grown on Cu foam (Cu/Cu(OH)<sub>2</sub> NRA/CF) were prepared <italic>via</italic> a three-step strategy involving the synthesis of Cu(OH)<sub>2</sub> NRA/CF, preparation and growth nanoparticles NRA/CF.
A single-stage high-frequency resonant ac/ac converter converts the ac-line input voltage into sinusoidal output voltage, which consists of two power conversion units, i.e., a factor correction (PFC) unit and dc/ac unit, it can be used to derive modular multichannel constant current LED driver. By adopting totem-pole bridgeless PFC boost rectifier reduce conduction losses, is proposed in this paper. The operating principle described, performance analysis presented detail. Moreover,...
