Design and efficiency analysis of stand-alone power conditioning system for fuel-cell

In this paper, a fuel-cell power generating system using interleaved full-bridge converter has been designed and efficiency analysis was implemented. To generate power from fuel-cell stack, DC-DC converter and DC-AC inverter is needed. DC-DC converter boost from low voltage of fuel-cell stack to high voltage and supplies the power to inverter. To improve efficiency of converter, optimum design is needed. System stability, range of ZVS, system losses on full-bridge converter are analyzed. A fuel-cell power generating system using interleaved full-bridge converter has been designed and efficiency analysis was implemented. Simulation and experiment was implemented to verify theological analysis considering the characteristics of fuel-cell.
