Abstract |
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.
