Abstract

The Boost converter is used for many applications, in hybrid electric vehicles, in medical equipment, as renewable energy sources, as Power Factor Correction [PFC] circuit, etc. This document proposes a new topology for the non-isolated threelevel dc-to-dc boost converter. This proposed system has a high voltage gain compared to the traditionalnon isolatedboost converter. The proposed dc-to-dcsystem is used in photovoltaic applications to extract the highest and constant output voltage from photovoltaics. The steadystate operation of the drive-in continuous conductionmode is analysed with a feedback circuit to extract the constant voltage with a high voltage gain for a resistive load. The performance of this proposed system is compared to the traditional non-isolatedboost converter. The proposed system is also simulated within the PSIM software to prove the calculations. The simulation results, show that the converter is one of the most suitable solutions for photovoltaic production systems.
