This paper analyzes the use of high-frequency signal injection methods for the sensorless control of doubly fed induction generators (DFIGs). High-frequency signal injection methods have been widely investigated for the sensorless control at very low speed and position control of induction machines and permanent-magnet synchronous machines. Most of these(More)
Fusion of phospholipid vesicles with photosynthetic chromatophores from Rhodopseudomonas sphaeroides was induced by freezing and thawing. After sucrose density gradient sedimentation, bands containing closed vesicles characterized by different phospholipid to reaction center molar ratios could be isolated and analyzed morphologically and functionally by(More)
Functional compatibility between the F1 and F0 parts of ATP synthases from Escherichia coli (EF1F0) and the thermophilic bacterium PS3 (TF1F0) was analyzed. F1-stripped everted membrane vesicles from both organisms bound the homologous or heterologous F1 part to the same extent. Titration of the reconstituted membrane vesicles with dicyclohexylcarbodiimide(More)
Mitochondria, isolated from the ubiquinone-deficient nuclear mutant of Saccharomyces cerevisiae E3-24, are practically unable to oxidize exogenous substrates. Respiratory activity, coupled to ATP synthesis, can, however, be reconstituted by the simple addition of ethanolic solutions of ubiquinones. A minimal length of the isoprenoid side chain (greater than(More)
