—This paper presents advanced step-up dc/dc converter intended for high voltage gains for distributed power generation systems. A novel topology named Quasi Z-source Multilevel DC-DC step-up isolated Converter (ML-qZDC) has been proposed in this paper. Here, the ML-qZDC based Photovoltaic (PV) array system with MPPT technique for medium frequency has been introduced. Two active bridges can produce any desired output voltage waveform across the transformer. A 7L-2L configuration has been investigated and affirmed on SIMULINK MATLAB to verify the proposed topology. The proposed topology in this paper has proved that, high quality boosted DC output is obtained with low harmonic distortion. The experimental results have proved the validity and effectiveness of this converter. The proposed scheme has a potential application in case of large scaled DC PV stations.
