Type: conference-paper
Abstract: This paper describes an independent AC based power production system that is fully powered by Proton Exchange Membrane (PEM) fuel cell and managed by an advanced adaptive approach. A two-phase Interleaved Boost Converter (IBC) is used to stabilize the low and fluctuating fuelcell voltage and supply a ripple-free and stable DC-link to the following power stage. To provide a high-quality AC power to the load, a Voltage Source Inverter (VSI) of three stages is implemented in combination with an LC filter. A unified control system that incorporates Adaptive Voltage Controller (AVC), Load Current Observer (LCO) and the Space Vector Pulse Width Modulation (SVPWM) is developed to improve the precision of voltage tracking, eliminate sensor reliance and harmonic operation. The outcome of the simulations show that the proposed configuration will give balanced sinusoidal output, robust disturbance rejection and a good steady-state performance when it is loaded by the RL conditions. Harmonic analysis establishes low distortion levels, a voltage THD of 1.86% and a current THD of 2.10 which is within the IEEE standards of standalone power systems. These results confirm the presence of the effectiveness of the approach suggested to provide stable, efficient, and highquality AC power based on fuel-cell-based distributed energy sources.
