About Course

Spurred on by technological progress and a growing concern about the efficient use of depleting energy resources, static power electronic converters employing advanced semi-conductor devices are currently used in an increasing number of applications. Such applications range from low power converters for miliwatt applications to converters for high-voltage dc transmission systems, handling hundreds of mega-watts. Other classical applications include adjustable-speed ac and dc drives for use in industry, switch-mode power supplies, audio amplifiers, uninterruptible power supplies and welding machines. In the last decade, power electronics and electrical drives have deeply penetrated the renewable energy sector. Today, power electronic converters provide vital functionality in a diversity of new technologies, including large wind turbine systems, fuel cells systems and photo-voltaic power generation. Further, motor drives comprising power electronic converters and advanced electric machines play a key role in the transportation sector, where new technologies are exploited in order to electrify many kinds of vehicle
