A New Single-Stage Three-Phase PFC for Four-Switch Three-Phase Inverter Fed IM Drives

Advances in Electrical and Computer Engineering, 2019
This paper proposes a single-stage three-phase power factor correction (PFC) for four-switch inverter (FSI) fed induction motor (IM) drives. The PFC scheme uses a Cuk converter with only one switch, and consequently, it needs only one control signal ...

Scn1a‐mediated developmental regulation of prefrontal cortex plasticity and cognition

Epilepsia, EarlyView.
Abstract Objective The voltage‐gated sodium channel Nav1.1, encoded by Scn1a, is essential for γ‐aminobutyric acid (GABA)ergic function, and its alteration is associated with neurological disorders such as Dravet syndrome and Alzheimer's disease. We previously demonstrated that local Nav1.1 dysfunction in the medial prefrontal cortex (mPFC) during ...

Use of Hydrogen Energy Storage to Stabilize Solar Power Output With an Energy Efficiency Analysis for European Union Member Countries

Energy Science &Engineering, EarlyView.
Photovoltaic solar power production can be stabilized using hydrogen energy storage. Gaseous hydrogen is produced, compressed, stored, and consumed in fuel cells to provide a constant power output. ABSTRACT Seasonal energy storage as compressed hydrogen offers a potential solution to balance the power grid as intermittent renewable energy sources are ...
