Performance Comparison of Standard and TwoPhase DC-DC Boost Converter

This paper presents steady-state performance comparison between standard boost converter and two-phase boost converter with reduced input current ripple characteristic. Several performance measurements were investigated under varying load conditions, which include output power, output voltage, input current ripple and efficiency. Results of the study using computer simulation reveal that the standard boost converter yielded input current ripple of 7.35% at full load while the two-phase converter draws a significantly less ripple of 0.01%. The difference, however, is not as pronounced on converter’s efficiency at full load with the standard boost converter having 92.4% efficiency while the two-phase boost converter achieved 95.69% efficiency.
