In a wide variety of industrial applications, an increasing demand exists to improve the quality of the energy provided by electrical systems. Besides the reliability and availability of electric power, the power quality is now becoming an important issue. Among the causes of the poor power quality, the harmonics are included as the reason which contributes the majority of power failures. Many efforts have been developed to solve the harmonics problem as, for instance, to install special devices such as active filters. This research work deals with the development of direct power control using the hybrid predictive control approach. The hybrid control considers each voltage vector of the converter as a discrete entity which will be applied to control a continuous linear system. One criterion to calculate the optimal voltage vector to apply will be established for the predictive control model. The optimal voltage vector to apply for each switching period, and the corresponding application time will be used to approach the actual value of the state variables of the system to the desired reference point. Two instantaneous power theories will be used, i.e. pq0 and pqr instantaneous power theory for a shunt active power filter application implemented in 3-phase 4-wire system. These instantaneous power theories have been developed to be applied to unbalanced systems using the power variables to obtain the currents that should be injected from active filters. The active filter will produce the required reactive power for the load and compensate the ripple component of active power so that the source only delivers constant active power

Given the importance of power converter safety operation in several fields (electric traction, renewable energy, etc ..), it is necessary to examine availability of these systems in the case of malfunction of an IGBT module, a converter leg or a phase machine. Thus, it is essential to develop new hardware architectures and software controls capable of operating at significant power after fault occurence. This thesis deals with a new multilevel fault tolerant hybrid topology. It consists on adding to a 3-phase 3-level NPC (Neutral Point Clamped) inverter, a fourth 3-level FC (Flying Cap) leg. New techniques of fault tolerance parts, namely detection, isolation, reconfiguration and system control during post fault mode, are proposed, analyzed and validated with a 15kW experimental converter prototype

The goal of this work is to build a benchmark for control and observation of multicellular converters series using the tools and theories of hybrid systems. The most important contributions of this work are: implementation of an experimental benchmark, using the hybrid approach to model the converter for the purpose of demonstrating the feasibility of this approach by establishing a hybrid automaton with different modes in order to represent the converter, apply high order sliding mode control theory to control a chopper multicellular combined with a RL load and then with a brushed DC motor, study the observability and synthesize observers for intermediate voltages by using the recent proposed theory of 'Z (TN) observability' for the converter from hybrid point of view. Observation strategies for intermediate voltages of the converter are studied: adaptive observer, step by step sliding mode observer and high order sliding mode observer (super twisting algorithm). All methods of control and observation presented in this dissertation have been experimentally validated through the benchmark which we have built

électrique.
Après avoir établi la caractéristique tension-courant des piles à combustible dont la forme justifie l'utilisation de
convertisseurs statiques, les structures à conversion continu-continu sont analysées en s'attardant sur la structure
élévatrice de base et sur la mise en parallèle de plusieurs d'entre elles. Cette dernière est une réponse satisfaisante
au caractère fort courant/basse tension des piles à combustible. Deux modes de réalisation des inductances du
convertisseur sont considérés. Pour le premier, les inductances sont indépendantes. Pour le deuxième, elles sont
réalisées sur le même circuit magnétique.
Un régulateur hybride de courant est ensuite proposé pour le contrôle du convertisseur continu-continu. Celui-ci
autorise une variation importante de la tension d'entrée comme c'est le cas en sortie d'une pile à combustible. Le
régulateur fonctionne à fréquence fixe et englobe les propriétés de trois modes de commande, la commande par
mode de glissement pour bénéficier de sa robustesse et les commandes de type commande à l'amorçage et au
blocage, afin de pouvoir assurer un fonctionnement correct du système, quelle que soit la valeur du rapport
cyclique. La stabilité du système au sens des valeurs moyennes basse et haute fréquences est considérée. Le
modèle moyen ne permettant pas d'étudier la nature exacte du cycle décrit par la trajectoire d'état du système, un
outil basé sur le calcul des multiplieurs de Floquet est élaboré. Il a permis de souligner la robustesse du régulateur
vis-à-vis de variations de l'inductance du convertisseur et de la tension d'alimentation de celui-ci.

This thesis is dedicated to the control and the observation of a class of switched linear systems (SLS). This class contains the systems that can be represented by a port-Hamiltonian model. A lot of works have been studied SLS for several years using an average modeling approach. Recently, various works have shown that hybrid system theory allows to cope with stabilization, controllability, and observability problems of switched linear systems. However, several problems are still open and need more development such as the design of hybrid observers for SLS that have unobservable modes or the control of systems with reduced number of switching inputs and numerous variable states to control. In this work, we are interested in the design of state observers for a particular class of SLS using both the average and the hybrid port-Hamiltonian models. This formalism has the necessary tools to study and establish the stability of the observation errors. At the beginning, a nonlinear observer based on the average modeling is proposed. Next, a hybrid observer is designed for switched linear systems. This observer takes into account the unobservable operating modes of the system. The second point of our work concerns the design of control laws for the considered class of SLS. At first, two Lyapunov-based control laws have been established using either an average model or a hybrid model of the system. A hybrid optimal control based on the maximum principle of Pontryagin and the computation of singular arcs has been also proposed. Finally, a hybrid predictive control based on a discrete model of the system is synthesized. Simulation results and an experimental implementation on a SEPIC converter are given to show the efficiency of the proposed methods. Our motivation to study such a converter is mainly due to its particular topology that includes observable and unobservable subsystems. It is also known to be difficult to be controlled because only one switching input is used to control four state variables

The increasing rise of distributed generation integration in the energy mix is a challenging issue. Indeed distributed generation based on renewable energy sources like solar and wind creates fluctuation of the grid’s parameter and can lead to minor issues like harmonics, over or under voltages, flicker and so on, or to major failure like blackouts. The concept of microgrid associated with energy storage systems is seen as a potential solution to increase renewable energy integration to the grid, while increasing efficiency and reliability at the same time.A review of energy Storage technologies is carried out and it results that currently none of these technologies can offer energy and power capabilities while fast response and efficiency at the same time. The use of Hybrid Energy Storage System allows to reach such performance. For this thesis, a Li-Ion and a Vanadium Redox Flow Battery have been selected for their good power and energy abilities respectively, and their high round trip efficiency.The main contribution of this work lies in the structural limits analysis of the topology and the control algorithm for the four leg three level NPC used as a multipurpose interface between a Renewable Energy Source, a Hybrid Energy Storage System and a Microgrid. The effectiveness of the proposed algorithms and limits model are tested both in simulation and experiments. Ancillary services like frequency and voltage support are then developed and tested in simulation under various conditions

This thesis deals with the development of a power conversion solution, allowing for the coupling of two similar voltage sources. Applied to a combined battery storage sys-tem power/energy for electric vehicles, the proposed solution presents a compromise between production costs, mass and energy performance, providing a better solution than those currently in existence. As such, the two voltage sources are coupled in series with a controlled current source. A structure of the converter allowing the coupling is studied and compared to a classic structure. Finally a demonstrator on a reduced voltage scale has been realized and shows advantages of this converter solution
