Characterization of silicon Geiger-mode avalanche photodiodes with novel device architecture [PDF]

open access: yes, 2011
Geiger-mode avalanche photodiode (GM APD) detectors are capable of counting single photons, measuring arrival times with high resolution, and generating zero read noise (when operated with a CMOS digital readout circuit) due to their unique internal gain

Transient stability of grid following inverters: The impacts of damping and fault ride‐through

open access: yesEnergy Internet, Volume 1, Issue 2, Page 150-165, November 2024.
Abstract The interaction of grid following inverters with a weak grid raises risks of transient instability. The effects of damping and fault‐ride through (FRT) make the transient dynamics more complicated. To investigate the impact of FRT on the transient stability of converters, this paper first employs the switch system theory to construct a ...

Active elimination of DC bias current of a SiC based dual active bridge by controlling the dead time period

open access: yesIET Power Electronics, Volume 17, Issue 14, Page 1960-1972, 4 November 2024.
The transient switching mismatch between the switch pairs S1 & S4 and S2 & S3 leads to average voltage deviations during turn‐on and turn‐off instants, resulting in a net DC average voltage. This problem is compounded due to the low winding resistance of the transformer and eventually leads to saturation of the transformer. Abstract Dual active bridge (

Improved Reference Infrared Spectrometer [PDF]

open access: yes, 2012
Infrapunasäteily on sähkömagneettista säteilyä, jonka aallonpituus on 750 nn - 1 mm. Se on tärkeä työväline optisessa spektroskopiassa, vaikka onkin ihmissilmälle näkymätöntä.

Improved reactive power sharing among photovoltaic inverters using Thevenin's impedance based approach

open access: yes, 2017
Unity power factor injection from rooftop photovoltaics (PVs) in residential distribution systems are creating voltage magnitude problems. One way to deal with this is to ensure reactive power sharing from PV inverters.

The use of flux temperatures in thermal design

open access: yes, 1981
The term ‘flux temperature’ is used here to denote a quantity with the status of a driving temperature made up as the sum of another temperature and a heat flow term.
