A battery charger for electric vehicles is to be designed. The charger should have advantageous impact on the utility grid, for example filtering capabilities, reactive power compensation, etc. several battery chargers forms a network where communication between the chargers and the vehicles and some distribution level master controller is an important issue. A possible battery charger topology is
During a series of HST/STIS observations of Eta Carinae and associatedejecta, we noticed a peculiar emission filament located a few arcsecondsnorth of the central source. While bright in nebular standards, it issubmerged in a sea of scattered starlight until moderately highdispersion, long-slit spectroscopy with the STIS (R 8000) brings theemission lines out. The initial spectrum, centered on 6768
