dc.description.abstractRenewable energy sources (RESs) such as photovoltaic panels (PV) and fuel cells (FC) are frequently equipped with DC-DC converters to regulate output voltage and to extract maximum energy because of their intermittent nature. In addition to regulation capability, the DC-DC converters need to increase low output voltage levels of RESs with their high gain capability. Although conventional boost converters are a good candidate to reduce the number of series-connected PV panels, they have recently been replaced by high voltage gain step-up DC-DC converters due to the disadvantages of limited voltage gain and high switching stress. The main aims of the high gain converters are to provide high voltage gain and to extract maximum power from the PV systems. In this paper, the benchmarking of maximum power extraction capabilities of high step-up DC-DC converters for PV-powered systems, have been presented. Three different high gain step-up DC-DC converter topologies: (i) quadratic boost converter (QBC), (ii) three level boost converter (TLBC), (iii) stacked boost converter (SBC) have been analysed under maximum power point tracking (MPPT) mode that uses the Perturb and Observe (P&O) algorithm. 5.11 kW PV-powered system has been modelled in the MATLAB/Simulink environment for each converter using same design parameters. The aforementioned converters are simulated under different irradiances: 1000, 900, 850, 750 and 700. The performance comparison of the converters has been conducted for such metrics; the maximum PV power, converter efficiencies, output current and voltage ripples. Performance results show that; the TLBC topology excels with the advantages of higher energy extraction capability and efficiency values. The efficiency values of the converters are 98.9%, 98.1%, and 96.5% for TLBC, SBC, and QBC, respectively.
