La volonté de diminuer la consommation en carburant en aéronautique amène à repenser les architectures de distribution et de conversion de puissance embarquées. L’utilisation d’un outil d’optimisation déterministe apparait comme une solution prometteuse pour prendre en compte les compromis intrinsèques aux convertisseurs statiques en pré-dimensionn...

Wide bandgap power transistors such as SiC MOSFETs and HEMTs GaN push furthermore the classical compromises in power electronics. Briefly, significant gains have been demonstrated: better efficiency, coupled with an increase in power densities offered by the increase in switching frequency. HV SiC MOSFETs have specific features such as a low short-...

Ces dernières années, l’utilisation des électrolyseurs pour produire proprement et efficacement de l’hydrogène à partir de sources d’énergie renouvelables (éolien, solaire) a profité d’un intérêt croissant de la part des chercheurs et également des industriels. De même que les piles à combustible, les électrolyseurs ont besoin de convertisseurs DC/...

Les applications de puissance dans lesquelles la température ambiante est élevée, provoquent l’augmentation de la température dans les dispositifs électroniques. De ce fait, il est important de développer les dispositifs électroniques pour pouvoir supporter des densités de courant et de puissance plus élevées. Dans cette thèse, nous avons pour obje...

Making use of renewable energy directly from the location of production requires converting source power into usable power. The specific scope of this project focuses on the DC to DC conversion within a user friendly universal farmbot system. Since renewable sources vary widely in voltage and current, a wide input-range DC to DC converter is desire...

DC-DC converters can be separated into two main groups: switching converters and linear regulators. Linear regulators such as Low Dropout Regulators (LDOs) are straightforward to implement and have a very stable output with low voltage ripple. However, the efficiency of an LDO can fluctuate greatly, as the power dissipation is a function of the dev...

This paper presents the development and study of multiple-input single-output converter (MISO) for the DC House project that utilizes a controller to maximize the overall converter’s efficiency. The premise of this thesis is to create uneven load current sharing between the converters at different loading conditions in order to maximize the efficie...

Tee-Resonant Dual Active Bridges are isolated, bidirectional, DC-DC converters that behave as voltage-controlled current sources, which makes them especially useful for battery charging applications. In this work, three new phase-shift modulation strategies are proposed that can improve the converter efficiency at high switching frequencies and ena...
