Conception d'une interface d'électronique de puissance pour Pile à Combustible

Abstract : The Fuel Cell (FC) is an efficient generator using hydrogen based fuel to produce electrical energy and thermal energy with low environmental impact. The extension of fuel cell applications depends essentially on the power electronics interface which adapts it to the load. This PhD research centres the conception of optimal power electronics interfaces for three fuel cell applications fields: transport, stationary and telecommunications.
In this purpose, modular approach which is based on unitary converter and connexion modes has been proposed to adapt to the stacks manufacturing feature of fuel cell. Losses models and dimensioning models of active and passive components like inductors, semi conductors have been presented. Interleaving technique has been applied to deal with the high current problem and to optimize the dimensioning of inductors. A new structure, named interleaved double dual BOOST – IDD BOOST, has been proposed to solve the voltage constraints such as: high output voltage, high voltage ratio. Multi-sources control strategies have been built to adapt to interface topology. Two prototypes were manufactured to validate losses prediction as well as control strategies.
