Analysis. Design. and Performance Evaluation of Asymmetrical Half-Bridge Flyback Converter for Universal-Line-Voltage-Range Applications

In this paper. a detailed analysis and design procedure of the AHB flyback converter for the universal line-voltage range is provided. The analysis of operation is illustrated by simulation waveforms obtained in Simplis. It is shown that the primaryside switches operate with zero-voltage switching (ZVS). whereas. the secondary-side rectifier operates …

Influence of Deposition Conditions on Silicon Nanoclusters in Silicon Nitride Films Grown by Laser-Assisted CVD Method

Crystalline-silicon-nanocluster-embedded silicon nitride films were deposited at low temperature using a laser-assisted CVD (LACVD) system with various reactant gas flow rates and assisting laser power densities. The photoluminescence (PL) performances of the resultant films were studied. showing a systematic spectra blue shift. and the enhancement of PL intensity with the …

Efficient authentication scheme for data aggregation in smart grid with fault tolerance and fault diagnosis

Authentication schemes relying on per-packet signature and per-signature verification introduce heavy cost for computation and communication. Due to its constraint resources. smart grid’s authentication requirement cannot be satisfied by this scheme. Most importantly. it is a must to underscore smart grid’s demand for high availability. In this paper. we present …

A New Digital Distance Relaying Scheme for Series-Compensated Double-Circuit Line During Open Conductor and Ground Fault

A new digital distance relaying scheme presented in this paper provides adequate protection to series-compensated double-circuit lines during a simultaneous open conductor and ground fault. The proposed scheme is based on the derivation of the compensated values of impedance using the symmetrical components theory. It measures the correct value of …
