The Modified SEPIC Converter with Extra Boost Unit and Without Coupling Inductor for PV Application
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
In this paper, the modified SEPIC converter with extra boost circuit and without coupling inductor is proposed for PV application using perturb and observe mppt algorithm. The proposed DC-DC converter has only one MOSFET switch with minimum voltage stress and this reduces the complex circuit design. The proposed converter is connected in between PV panel and load to obtain high voltage without extreme duty ratio. In this paper input voltage of 40V is obtained from PV panel is fed to converter in order to obtained output voltage of 400V with switching frequency of 100kHz. Thecircuit operation and passive parameter design of this proposed converter are discussed in details.
