A New Fully Soft‐Switching High Step‐Up Interleaved Converter for Optimal Efficiency

open access: yesIET Power Electronics
A novel fully soft‐switching interleaved high step‐up converter is introduced in this paper. The suggested converter achieves high voltage gain using coupled inductors (CI) and a voltage multiplier cell (VMC).

Analysis of Switching-Loss-Reduction Methods for MHz-Switching Buck Converters [PDF]

open access: yes2007 IEEE Conference on Electron Devices and Solid-State Circuits, 2007
Numbers of switching-loss-reduction methods recently proposed for MHz-switching buck converters are thoroughly investigated. From a theoretical perspective, switching loss is found to be effectively minimized by adapting the width rather than the turn-on voltage of power transistors of a buck converter.

Analysis of power converters with devices of SiC for applications in electric traction systems [PDF]

open access: yes, 2016
This article presents the analysis of two topologies of power converters. Voltage Source Inverter (VSI) and Current Source Inverter (CSI) proposals for traction system applications, these topologies are implemented with silicon carbide devices.

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Low-loss AlInN/GaN microwave switch

open access: yesElectronics Letters, 2011
A report is presented on the first low-loss monolithic microwave integrated circuit switch using AlInN/GaN heterostructure field effect transistors. Owing to significantly lower sheet resistance compared to the conventional AlGaN/GaN heterostructure (215 against 280 Q/□), and lower contact resistance (0.27 against 0.5 Ω×mm), the microwave switch based ...

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Comparison between unipolar and bipolar single phase grid-connected inverters for PV applications [PDF]

open access: yes, 2007
An inverter is essential for the interfacing of photovoltaic panels with the AC network. There are many possible inverter topologies and inverter switching schemes and each one will have its own relative advantages and disadvantages.
