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 …
