| Abstract |
An overview of key areas in the field of power electronics is given as well as
perspectives. Areas that need new solutions and research are discussed with focus on adjustable speed drives, ASDs. The compatibility between power electronics and the motor and its driven object is covered in some details. Parasitic effects: noise, bearing currents,
insulation stresses, etc. are mentioned. The potential impact of new materials in electrical machines is indicated, e.g., powder-iron for magnetic circuits, and chromium oxide for winding insulation resistant to partial discharge, PD. IntegralMotors are now on the market while SmartMotor is a vision to communicate on an Intranet. Trends in power transmission and distribution, T &D, as well as in power generation are reviewed. A view on the Scandinavian
countries as partners in the Nordel and to UCPTE is given. Medium-voltage de, MVDC, distribution is an exciting possibility and might be used in sea-based wind-power plants.
Variable-speed generation, VSG, and solar cells, PV, are examples where power electronics is essential. Neoelectrification summarises the trend for quick and sustainable manufacturing
technologies in several industries. Several references are given, both conventional scientific ones and to Internet. Anticipated impacts, benefits, global and environmental aspects, and
sustainable technologies are used as guides through the keynote paper. |
