dc.description.abstract | Nowadays, because of pollution problems of the fossil fuels and their unpleasant effects on the earth planet and people life, renewable energy sources such az photovoltaic
(PV) cells and fuel cells are considered to produce electrical energy. These
sources directly convert solar energy and chemical energy to electrical energy, respectively.
Since the output voltage of PV cells is low, a high step-up dc-dc converter is
needed to increase this low voltage to meet inverter input required voltage.
In this thesis, a novel high step-up dc-dc converter (which is the derivation of
z-source converter) is introduced. This converter has a higher voltage gain in comparison
to the conventional converters. This advantage makes this converter a suitable
choice for high step-up applications, such as boosting the low output voltage of
solar panels. Also, by choosing appropriate turns ratio of the coupled inductors, the
proposed converter can be used for a wide range of voltage gain.
First, the z-source converter is analyzed and the conventional high step-up converters
are discussed. Then, the new high step up converter is proposed and analyzed.
The converter is simulated and the results are compared to the theoretical results.
The proposed converter is then experimentally tested. The experiment results verify
the theoretical and simulation results. Finally, the proposed converter is compared to
the conventional ones and it’s advantages such as having higher voltage gain are
confirmed. | en |
