Convertisseur bidirectionnel à haut rendement pour récupérateur d'énergie sur réseaux de transport urbain

Abstract : The increasing growth of activity and traffic in city obligates users to reconsider their urban trips. In the past few years, we could notice a trend of shifting from polluted private vehicles to sustainable public transportation. In order to assist this transition, network operator extends consistently their lines and increase vehicles flow rate. Most of the newly added lines are dedicated for electric vehicle fed by an overhead catenary. This thesis work consists in designing a power converter tailor-made for energy recovery of electric urban traffic vehicles. A design process is proposed and applied on basis of the standard requirements in railway area and the specific needs of the application. As a result, an optimal layout using an innovating topology is obtained from our method. Then, this new topology is deeply study and two new modulation principles are presented. These control modes are compatibles each other and extended the capabilities of the converter. By gathering all the equation of the previous study, an assessment of the semiconductor losses is made and the overall efficiency is verified. At last, the applied waveforms on the magnetic components are examined. The initial selection of materials is finally verified with help of simulation
