Servavidya Kumar Manas, Bharat Bhushan . Performance Analysis of Conventional, Quadratic and Double Cascaded Boost Converters in a PV System with P and O based MPPT Controller. International Journal of Computer Applications. 176, 40 ( Jul 2020), 26-33. DOI=10.5120/ijca2020920507
In this paper, performance analysis of three different DC/DC converter topologies i.e. a conventional, a quadratic and a double cascaded boost converter for a Solar PV system, driven by Perturb and Observe based MPPT controller is proposed. A boost topology is used to increase the output voltage of a solar PV module. However, for the case where high step-up ratio is required, a conventional boost converter may not fulfill the purpose and therefore cascaded boost converters are employed to overcome this limitation. Cascaded boost converters provide high voltage conversion ratio along with higher efficiency values, in comparison to conventional boost converter. Perturb-and-observe (P&O) technique is a very widely used technique for operating the solar PV system at maximum power point, because of its simple structure, simplicity of algorithm and its low-cost implementation in a microcontroller based real systems. This MPPT algorithm extracts the maximum power point from the PV panel module corresponding to a constant load resistance under various pairs of solar radiation and ambient temperature. For all the three converter topologies. MATLAB/ Simulink software is used to simulate the circuits. The results are compared to evaluate the overall performance of the Solar PV system in each case.
