MODIFIED DUAL-SWITCH BOOST DC–DC CONVERTER FOR FUEL CELL VEHICLES

  • Unique Paper ID: 180377
  • PageNo: 1226-1231
  • Abstract:
  • A DC-DC converter designed for fuel cell vehicle applications must deliver high voltage gain, low voltage stress on components, compact size, and high efficiency. Traditional converter topologies such as two-level, three-level, and cascaded boost converters often fall short in fulfilling these criteria. To address these limitations, a novel non-isolated converter incorporating a switched-capacitor network is introduced. This design achieves a significant voltage gain, supports a wide input voltage range, maintains low voltage stress across the components, and offers a common ground configuration. The proposed high-gain converter ensures continuous input current, reduced voltage stress, and a minimal component count, all while maintaining a grounded architecture. A detailed steady- state analysis is carried out in continuous conduction mode (CCM), and its performance is compared with other state-of- the-art converter designs. Simulation studies, performed using MATLAB/SIMULINK, confirm the theoretical predictions and demonstrate the efficiency and effectiveness of the proposed topology. For experimental validation, a hardware prototype is built using the TMS320F28027F microcontroller. With an input voltage of 2V, the prototype successfully delivers an output of 9V, achieving a voltage gain of 4.5. Under rated operating conditions, the converter attains a peak efficiency of 93.1%
