Simulations of Interleaving Two Switched-Inductor Hybrid DC Boost Converters For Fuel Cell Applications

Abstract

This research paper introduces the interleaving of two
switched-inductor hybrid units for increasing output DC
voltage of a DC converter. The benefits of the proposed
converter include high DC voltage gain and reduced ripple
current. The proposed converter operates in four modes,
working of all the four modes are discussed. A conventional
method of controlling the proposed converter is adopted.
Simulated steady state analysis including waveforms of
converter input current, inductor current and voltages,
power electronics switching device current and voltages,
output load current and voltages are presented. Results
show that the proposed converter demonstrates the
maximum efficiency of approximately 85% at a duty ratio of
0.4.
