Power factor correction using a boost quasi-resonant converter
, 2009 A steady-state analysis of a quasi-resonant zero current boost converter is performed in its application to a single-phase power factor correction circuit. The known closed-form expressions are used to design the boost converter and the multiloop control

Power factor correction using boost converter technique: article / Nur Zati Akmar Lukeman [PDF]
, 2013 This paper describes a single phase rectifier with improved power factor by using the boost converter technique. Low power factor is caused by non-linearity of the input current.

Advanced Engineering Materials, EarlyView.Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

A Low Common Mode Noise Bridgeless Boost-Buck-Boost Power Factor Correction Rectifier
, 2012 In this paper, a new topology for single phase power factor correction (PFC) rectifier is proposed with the intent to reduce the common mode current. The proposed PFC rectifier merges the boost and buck-boost converter by sharing an inductor and removes ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...
