Abstract
DC to DC conversion at high voltage gain is an imperative feature for many applications particularly for photovoltaic grid-connected system. The voltage conversions at large gain in boost converter are restricted due to the diode reverse-recovery problem and the stress on the switch. In this paper, a hybrid boost converter (HBC) that operates at high voltage gain is analyzed. This converter topology has better features like large voltage conversion for the smaller duty cycles, reduced voltage and current stress on the active switches. Also, the dynamic performance of the HBC is analyzed in the closed-loop operation with fuzzy logic controller for the variations of supply voltages and load resistances. The simulation model of 400 V, 10 KW HBC is designed and implemented in MATLAB/Simulink, and the obtained results verify the better performance of HBC over boost converter.
