2. 1. Modeling and testing of line start permanent magnet motors

   Author : Tomas Modeer; Chandur Sadarangani; Jörgen Engström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; line start permanent magnet; flux integration; step response; Electrical engineering; Elektroteknik;

   Abstract : This licentiate thesis describes the modeling and measurements performed with the aim of developing design guidelines for Line Start Permanent Magnet Synchronous Motors, LSPMSMs. LSPMSMs can offer higher efficiency than standard induction motors used in the industry today, especially for small motor sizes.

4. 2. Cascaded Converters with Gate-Commutated Thyristors : Experimental Verification and Auxiliary Power Supply

   Author : Tomas Modeer; Hans-Peter Nee; Staffan Norrga; Dragan Jovcic; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis describes an effort to investigate the use of gate-commutated thyristors(GCTs) in cascaded converters. Cascaded converters, such as modularmultilevel converters (M2Cs) and cascaded H-bridge converters (CHBs), haveproved to be especially suitable in high-voltage, high-power applications. READ MORE
