Investigation of inter feeder power flow regulator: Load sharing mode
(2010 , Article)
The Inter feeder Power Flow Regulator (IFPFR) proposed in this paper consists of several voltage source inverters with common dc bus; each inverter is connected in series with one of different independent distribution ...
Switched mode power supplies for charge-up, discharge and balancing dc-link capacitors of diode-clamped five-level inverter
(
IET
, 2010 , Article)
Inductor switch mode power supplies (SMPS) operated in a discontinuous inductor current mode are used to balance the dc-link capacitor voltages of a diode-clamped five-level inverter. The SMPS concept is extended to charge ...

(
Elsevier B.V.
, 2010 , Article)
The efficiency of iron coated activated alumina, ferric oxihydroxide and granular activated carbon for the removal of humic substance (HS) from water and wastewater was demonstrated in batch studies. This paper investigated ...
Bioenergy II: Bio-ethanol from municipal solid waste (MSW): The role of biomass properties and structures during the ethanol conversion process
(
Berkeley Electronic Press
, 2010 , Article)
The emerging biofuel industry demands large amount of biomass feedstock. Although commercial ethanol has been produced from primary biomass sources such as corns, the global food crisis caused by the use of primary biomass ...
Kinetics of humics removal from water and wastewater using granular activated carbon, iron-coated activated alumina, and beta ferric oxihydroxide
(2010 , Article)
Application of kinetic models to represent the removal of humic substances from water and wastewater was investigated. An adsorbate-adsorbent system was represented by humic substances and three adsorbents, namely granular ...
