SiC heat pump converters with support for voltage unbalance in distribution grids [PDF]
2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015 This paper studies the impact of involving the demand side of the LV grid into the grid conditioning process. Heat pumps are distribution loads with a substation capacity increase in the last years, with expectancy of growth in the coming years. Controlling the loads is the first step in the transition to smart grids, and heat pumps are to be the first

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.

An improved digital phase locked loop against adverse grid conditions
Energy Reports, 2022 The phase-locked loop (PLL) is an essential synchronization technique to ensure stable operation and control of grid-connected converters. Nevertheless, under actual conditions, the grid voltage is often influenced by harmonics and frequency variation ...
