Switched reluctance motors for electric vehicle propulsion: comparative numerical and experimental study of control schemesPetrus, Vlad 21 September 2012 (has links)
Policies to reduce emissions from transportation are implemented by different World and European<p>associations. Personal and freight transportation is one of the key contributors in GHG<p>emissions, being the second biggest GHG emitter after energy sector in the European Union.<p>The policies to reduce emissions from transportation are focusing on the optimization of the efficiency<p>of the existing vehicles, the development of new sustainable fuels and propulsion systems<p>and the electrification of the vehicles<p>The continuously increasing price of the permanent magnets and the shortage of rare earths<p>demand the finding of alternatives for the permanent magnet synchronous machines which is<p>currently the leading technology in several domains as hybrid and full electric propulsion and<p>wind turbines due to their best overall performances.<p>The good efficiency and the large constant power-speed ratio in addition to low the cost, high<p>reliability and fault-tolerance make the SRM a candidate with real chances on the market of<p>vehicle propulsion. The main drawbacks of the SRM related to the torque ripple, noise and<p>vibration make the research object in R&Ds all over the world.<p>This thesis is focused on the development of an efficient and robust switched reluctance drive<p>which can be integrated in a hybrid dive train or can be solely used for electric vehicle traction.<p>To achieve this goal, various instantaneous and average torque control techniques are implemented<p>and compared. A converter is designed, built and integrated on a test bench which<p>allows testing SRMs for vehicle propulsion. An investigation on noise production in SRDs ends<p>the thesis. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished
