  2. 1. Control, Modulation and Implementation of Modular Multilevel Converters

    Author : Antonios Antonopoulos; Hans-Peter Nee; Colin Oates; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular Multilevel Converter; Modulation; Feedback Control; Open-Loop Control; Implementation; Prototype; High-Performance Motor Drives; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Denna avhandling behandlar analys och styrning av den modulära multinivå omvandlaren (M2C). M2C är en lovande omvandlarteknologi för högspända högeffekttillämpningar. Anledningen till detta är låg distorsion i utstorheterna kan uppnås med låg  medelswitchfrekvens per switch och utan utgångsfilter. READ MORE

  4. 2. Dynamic analysis of a novel electromagnetic transducer for hybrid vehicle and experimental verification

    Author : Sylvain Chatelet; Chandur Sadarangani; Jorma Luomi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Machines and Drives; Electrical engineering; Elektroteknik;

    Abstract : This thesis presents the results of the work carried out on the dynamic analysis and experimental performance measurements of a novel concept of electromagnetic system for hybrid vehicle powertrains. The main focus of this work is to present how this novel electromagnetic system can be operated in a hybrid vehicle and to show how a prototype of this system has succesfully been operated in a laboratory set-up.

  5. 3. A Permanent Magnet Traction Motor for Electric Forklifts : Design and Iron Loss Analysis with Experimental Verifications

    Author : Yung-Kang Robert Chin; Chandur Sadarangani; Fabio Crescimbini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Abstract : This thesis presents the design analysis of a permanent magnet synchronous motor (PMSM) for the traction application in electric forklifts. Within the scope of the study, an existing induction traction motor for electric forklifts benchmarks the expected performances of the proposed PMSM designs, as design specifications. READ MORE

  6. 4. Improved performance characteristics of induction machines with non-skewed symmetrical rotor slots

    Author : Rathna Chitroju; Chandur Sadarangani; Kelvin C Maliti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; skewing; cross current losses; radial magnetic forces; magnetic noise; asymmetrical rotor slots; eccentricity; stator vibration; two-dimensional fast fourier transform; finite element method; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. READ MORE

  7. 5. Analysis of a novel Transversal Flux Machine with a tubular cross-section for Free Piston Energy Converter application

    Author : Alija Cosic; Chandur Sadarangani; Nicola Bianchi; KTH; []
