Continuité de service des convertisseurs triphasés de puissance et prototypage "FPGA in the loop" : application au filtre actif parallèle

Abstract : Voltage source converters (VSC) are essential components of many power electronics systems such as variable speed AC machines, uninterrupted power supplies and active power filters. A sudden failure in one of the used power switches or the current sensors decreases system performances and leads to disconnect the system. Moreover, if the fault is not quickly detected and compensated, it can lead to hard failure. Hence, to reduce the failure rate and to prevent unscheduled shutdown, effective and fast fault detection and compensation schemes must be implemented. In this thesis work we have studied a fault tolerant VSC. This converter provides the continuity of service in the presence of a semiconductor or a current sensor fault. In this work, we have chosen the shunt active power filter application to validate the studied fault tolerant VSC performances. The experimental results confirms the satisfactory performances and efficiency of the proposed fault tolerant VSC. To minimize the fault detection time, we targeted a FPGA (Field Programmable Gate Array) component. We also proposed in this thesis a new methodology to design and prototype so-called "FPGA in the Loop" that will reduce development time of the digital controllers.
