Full textTo increase railway traffic, the quality of the electrical power supply is crucial. On the one hand, it is necessary to guarantee a satisfactory voltage level for the proper operation of traction units and, on the other hand, to ensure that the energy drawn from the upstream electricity transmission network meets quality standards. For 25kV/50Hz electrified lines, the increase in power consumption can only be tolerated by the power supplier if the voltage unbalance, due to the substation connection between two phases, is minimal. To meet this constraint and to meet the challenge of increasing traffic on its lines, SNCF-Réseau has to rely on power electronics solutions.The balancing systems currently used by SNCF-Réseau are based on three-phase voltage inverters. These systems have high losses, and their maintenance is complex. It is against this background that a new low-loss modular topology was proposed in 2016 as part of an ANR project led by LAPLACE and involving industrial partners SCLE and CIRTEM. This solution is based on a Steinmetz compensation circuit controlled by PWM AC choppers.This thesis was carried out as part of the “High Voltage Balancing System” (HVBS) project, funded by the France 2030 program operated by ADEME. The aim of this project, which began in 2019, is the design, development, and industrial realisation of a new unbalance compensator topology dedicated to 25kV/50Hz railway substations.This thesis first presents the future prospects for railway traffic, followed by a state-of-the-art review of unbalance balancing topologies. Subsequently, a comparative study, considering semiconductors losses and the reactive elements stored energies, highlights the advantages of the proposed new solution.Two design tools, considering the power consumed by the substations, are then presented. One is dedicated to conventional single-phase substations, while the other concerns "V" scheme substations, mainly used for the power supply of high-speed lines.To prepare for the installation of the compensator on the power transmission network, a harmonic analysis of the current absorbed by the substation must be carried out. This is then used in a simulation model to check that there are no interactions between the three-phase high-voltage network, the compensation system, and the substation. This demonstrates the robustness of the compensator and its control against harmonic disturbances generated by the trains.Finally, the last part of this thesis is dedicated to the realisation and testing of an experimental branch connected to the 20kV network and comprising 54 PWM AC choppers connected in series. The experimental results obtained on SCLE's test platform are presented. They validate the proper operation of the developed solution and pave the way for its installation in one of the critical substations of the national railway network
