چکیده
In this paper, a Multi-Input Multi-Output (MIMO) high step-up transformerless DC-DC converter is proposed. The proposed can expand the number of ports from both input and output terminals. Also, it has modular structure using voltage multiplier cells (a switch, two diodes, capacitor, an inductor). useful for wide range applications merit interfacing multiple hybrid sources with each other to supply different loads various levels. All voltages be regulated at same time by tuning separate controlling parameters. Since digital control benefit (1) enhancing efficiency, (2) higher flexibility than analog electronics, (3) ease use, (4) improving reliability stability in energy conversion applications, method implementation adopted. key contributions article would 1) expandable MIMO performance all duty cycles; 2) integration delivering loads; 3) nonlinear approach achieve fast transient response under variation loads, 4) gain low normalized power stress on switches. To simplify analysis, first, single-input, dual-output (SIDO) mother-module, dual-input, three-output (DITO) three-input, four-output (TIFO) developed modules are carefully analyzed then, explained. verify theoretical results, prototype SIDO operation scheme implemented 30V /150V, 250V total 450W. Furthermore, experimental results DITO 40V voltages/150V, 250V, 405V 800W extracted.
