Implementation of Floating Output Interleaved Input DC-DC Boost Converter

This paper explores and presents the analysis, design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced output voltage and output current ripple, also reduces the voltage and current rating of power electronic components compared with conventional boost converter. The voltage stress on the switches are reduced in this topology. Analysis, design and converter operating waveforms in the continuous conduction mode are provided along with design guidelines. The converter has been designed for rated power of 50W, input voltage of 24V, output voltage of 72V and switching frequency of 25 kHz. The floating output interleaved input high voltage gain converter is compared with conventional boost converter, hardware and simulation results are verified.
