A SEPIC-Cuk-CSCCC Based SIMO Converter Design Using PSO-MPPT For Renewable Energy Application
Abstract
Background and Objectives: The increasing requirement of different voltage and power levels in various power electronics applications, especially based on renewable energy, is escalating the growth of the different DC-DC converter topologies. Besides single-input single-output (SISO), multi-input multi-output (MIMO) type topologies become famous. So, in this paper, a Single-Ended Primary Inductance Converter (SEPIC), Cuk and Canonical Switch Cell (CSC) based single-input multi-output (SIMO) boost converter is proposed with a maximum power point tracking (MPPT) controller.Methods: The Design of the three different DC-DC converter-based SIMO topology has been developed and thereafter the operation of the proposed converter is verified with Solar Photovoltaic (SPV), connected as an input to the converter. To extract maximum power from the SPV and MPPT controller is also developed. Finally, the converter's transfer function is developed using small-signal analysis and the system's stability is analyzed with and without compensation.Results: A MATLAB simulation has been done to verify the theoretical analysis. Successful extraction of the maximum power from the SPV panel (65W, Vmpp 18.2V, Impp = 3.55A) with Particle Swarm Optimization (PSO) is verified. SEPIC and Cuk-based DC-DC converter can successfully operate in boost mode with a gain of 2.66. A significant reduction in the Cuk converter capacitor voltage ripple is also established.Conclusion: So, this paper represents an SPV-fed SIMO boost converter based on SEPIC Cuk CSC topology. In addition to that, a PSO-based MPPT controller is also introduced for maximum power extraction. Verification of the theoretical analysis with simulation results is also described.
