	Comparison of different Low Voltage Multilevel Converter Topologies for Distributed Power Generation   By Ingmar KAISER	[View]   [Download]
Abstract: Typically converters for distributed power generation built with IGBTs have a poor partial load efficiency. Multilevel converters with low voltage SI MOSFETs can be an attractive alternative regarding partial load efficiency and semiconductor cost. In this paper, different multilevel topologies with low voltage SI MOSFETs are compared.
	Experimental Validation of the Performances of an Inverter Sized with Optimization Methods   By Adrien VOLDOIRE	[View]   [Download]
Abstract: This work shows the experimental performances of a PWM inverter designed with a fast design automation tool. The chosen optimization method uses a deterministic algorithm with continuous equations. Analytical models are used to design active and passive components under loss, harmonic, thermal and efficiency constraints. Precise calorimetric test benches are used to measure the losses, and an original method is proposed to measure capacitor currents. Then, the results given by the optimization tool, presented as Pareto front, are discussed. A 10kW prototype was built to compare the constraints between the optimization results and the experimental values.
	On the switching-induced dc-link voltage ripple in three-level converters with a neutral point   By Ioannis TSOUMAS	[View]   [Download]
Abstract: The operation of a three-level (3L) converter with a neutral point (NP) employed in a medium voltage (MV) wind energy conversion system (WECS) is investigated. In particular, the voltage ripple of the upper or the lower half of the dc-link and its dependence on the relative phase of the carriers in a carrierbased pulse width modulation (CB-PWM) scheme is investigated. It is shown that the carrier phase has no influence on the half dc-link voltage ripple.
	Optimization strategy for the sizing of passive magnetic components   By Guillaume DEVOS	[View]   [Download]
Abstract: This paper presents an optimization methodology for the design of magnetic components embedded in aeronautical structures. We want to realize a multi-objective optimization of an inductance, taking into account some physical phenomenon that are not easily described with mathematical formulations, and to set up a methodology that allows us to harvest optimization time. We will use, for that purpose, analytical formulations, Finite Element Analysis (FEA), and a neural network to reduce the time consumption of components evaluation.
	Review of optimization methods for the design of power electronics systems   By MYLENE DELHOMMAIS	[View]   [Download]
Abstract: Optimization methods for the design of power electronics are increasingly used. The variety of methods is rich but can be confusing for designers who wish to start using them. This article is an introduction to optimization methods that can be applied in power electronics through a review of the literature.
