Study of Controllers for an Isolated Full Bridge Boost Converter Topology in Fuel Cell Applications: A Comparative Approach | Chapter5 | Newest Updates in Physical Science Research Vol. 13

In recent years, renewable energy sources have become a fascinating study topic, and fuel cells have emerged as a viable alternative for generating power to address the energy crisis. This sparked interest in power conditioning systems, which connect the fuel cell to the grid. Among the several converter topologies, the isolated full bridge boost converter (IFBC) is the most suitable for fuel cell applications. This paper proposes a Predictive Switching Modulator (PSM) Control for the converter architecture, and its performance is compared to Linear Peak Control. Non-Linear Carrier Control (NLCC) and Current Mode Control (LPCM) (NLC). Three controllers (LPCM, NLC, and PSM) are used to operate the chosen IFBC converter, and simulation is performed using MATLAB with a fuel cell as the input source. The three controllers are then evaluated in terms of time response parameters, with the suggested PSM control emerging as the superior controller for obtaining quick responses while overcoming uncertainties and maintaining steady state stability.
