Edité par HAL CCSD

International audience. This article deals with the model order reduction by state residualization of power electronic converters. It presents a method to a priori estimate the error induced by this reduction. This method helps choosing the most suitable reduced model, the one that minimizes the error, depending on the simulated events. When applied to a system with several converters, it helps choosing which converter to reduce and how much, in order to simplify the models while keeping a sufficient accuracy.
