Effect of duty ratio on fuel cell ripple current, power losses and converter efficiency
The duty cycle of the switch impacts the Fuel Cell (FC) ripple current and the efficiency of the converter. To analyze the effect of duty cycle on FC ripple current and efficiency of the DC-DC converter, a (Polymer Electrolyte Membrane Fuel Cell)PEMFC stack of rating 24 kW, 180 V is considered as input supply source incorporated with the multi device multi-phase interleaved boost converter (MDMPIBC) converter. The converter switches are operated with various duty cycles 0.25, 0.35 and 0.55. The FC ripple content and converter efficiency for different duty ratios are evaluated with the help of simulation wave forms. For each duty cycle the input current ripple and I/O power of converter is plotted and measured. The comparisons for various duty cycles are given with respect to FC ripple current, converter power losses and efficiency. The study shows that the optimum duty cycle for the converter is 0.25.
