Refrigerant Charge Fault Detection and Diagnosis Algorithm for Water-to-Water Heat Pump Unit
Energies, 2019 Refrigerant charge faults have a great adverse effect on the performance of heat pumps and must therefore be detected and diagnosed early in real time. In this study, the effect of refrigerant charge faults on a water-to-water heat pump is experimentally

Design of a dual-input cross-connected charge pump utilizing scavenged energy
Energy Reports, 2020 This paper presents a novel dual-input cross-connected charge pump utilizing scavenged energy. The proposed converter has two input sources: a battery input and a scavenged energy input. Unlike existing charge pumps, the proposed converter alleviates the

Electronics Letters, 2006 A low-voltage charge pump, having a symmetrical structure, is proposed. In this charge pump, enhanced switches are used instead of diode-configured MOSTs. The switch-controlling voltage is mutually offered by the two symmetrical branches, which makes the enhanced switches turn on/off alternatively during the designated cycles. Consequently, the voltage

Statistics of an adiabatic charge pump
, 2015 We investigate the effect of time-dependent cyclic-adiabatic driving on the charge transport in quantum junction. We propose a nonequilibrium Greens function formalism to study statistics of the charge pumped (at zero bias) through the junction.

Charge density wave and charge pump of interacting fermions in circularly shaken hexagonal optical lattices [PDF]
, 2018 We analyze strong correlation effects and topological properties of interacting fermions with a Falicov-Kimball type interaction in circularly shaken hexagonal optical lattices, which can be effectively described by the Haldane-Falicov-Kimball model ...

Comparison of positive and negative Dickson charge pump and Fibonacci charge pump [PDF]
2017 International Conference on Applied Electronics (AE), 2017 An operation of electronic equipment is dependent on a power supply. Today, a trend of only one AC/DC adapter is used for supplying an electronic system. Thus, an electronic equipment with various power supply requirements uses some internal DC/DC converters.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
