The electric warship [electric propulsion]

摘要: Integrated full electric propulsion has become a normal first choice for several commercial operators, in particular cruise ships where it proves to be fuel efficient transmission system. Operating profiles warships of frigate size and above are similar with long periods at well below power. However the size, weight initial cost equipment generally prevented selection warships. With application modern technologies, power densities being increased such that integrated now serious competitor mechanical systems traditionally adapted The authors discuss PM motor technology, semiconductor devices (GTO, IGBT, MOS controlled thyristors), variable speed drives.
