ABSTRACT
Our project consists in the study, the design and the realization of a Forward converter. The design of a forward converter demands great precision when calculating the different parameters and restrictions that will have to be applied when conceiving the model. The first step was the understanding of the forward converter in order to know the main parameters needed and the different mathematical equations for the choice of the different components of the forward. The use of the software PSIM completes this work for the comprehension,the collection of different values and for the checking of the circuit calculations. Once this had been done it was possible to proceed to the construction and to the test the forward converter in the laboratory. These different tests allowed us to validate the performed design and simulations. Then we have controlled the output voltage of the forward converter with a feedback control circuit in order to assure the optimal function of the forward and automatic control of the different parameters.
RESUME Ce projet a pour but l’étude et la réalisation complète d’un convertisseur Forward s’inscrivant dans un cahier des charges bien précis afin d’être tester. Un travail préliminaire portant sur l’étude qualitatives du convertisseur permet de dégager les nombreux paramètres qu’il sera nécessaire de surveiller ainsi que d’obtenir les différentes équations mathématiques utiles pour dimensionner les éléments constitutif du convertisseur. La simulation par outil informatique vient compléter cette démarche amont et nous aide ainsi à accéder à des résultats qu’il convient de confronter une fois le prototype réaliser. Ensuite le convertisseur une fois dimensionner, en ayant respecté au maximum le cahier des charges est construit puis testé. Ces différents tests nous permettent de valider notre convertisseur et les simulations effectuées. Enfin l’intégration dans une chaine de contrôle permet d’asservir le convertisseur tout en assurant un fonctionnement optimal de ce dernier et le contrôle des différents paramètres.

ABSTRACT
The high demand of energy efficiency has led to the development power converter
topologies and control system designs within the field of power electronics. Recent advances of
interleaved boost converters have showed improved features between the power conversion
topologies in several aspects, including power quality, efficiency, sustainability and reliability.
Interleaved boost converter with multi-phase technique for PV system is an attractive area
for distributed power generation. During load variation or power supply changes due to the weather
changes the output voltage requires a robust control to maintain stable and perform robustness.
Connecting converters in series and parallel have the advantages of modularity, scalability,
reliability, distributed location of capacitors which make it favorable in industrial applications. In
this dissertation, a design of μ-synthesis controller is proposed to address the design specification
of multi-phase interleaved boost converter at several power applications. This thesis contributes to
the ongoing research on the IBC topology by proposing the modeling, applications uses and control
techniques to the stability challenges. The research proposes a new strategy of robust control
applied to a non-isolated DC/DC interleaved boost converter with a high step voltage ratio as
multi-phase, multi-stage which is favorable for PV applications. The proposed controller is
designed based on μ-synthesis technique to approach a high regulated output voltage, better
efficiency, gain a fast regulation response against disturbance and load variation with a better
dynamic performance and achieve robustness. The controller has been simulated using
MATLAB/Simulink software and validated through experimental results which show the
effectiveness and the robustness.
