High Gain Coupled Inductor-Based Dc/Dc Converter For Offshore Wind Energy Systems
International Journal Of Engineering And Computer Science
Now a days power demand are increased to reduce the power demand using renewable the energy systems. With the increasing integration of renewable energy generation into high-power grids, transmission at the dc level is becoming increasingly more useful than ac transmission. In this regard, emerging application, such as offshore wind farms, require a high-power offshore wind energy systems. The proposed dc/dc converter is characterized by the resonant switching transitions to achieve minimum
... ching losses and maximum system efficiency. Therefore, a higher switching frequency is conceivable to attain a higher power density. The double stage output voltage of the proposed converter operates at seven times as high as the input voltages with a small device count. The output capacitors are charged and discharged continuously by a 180 phase shift with respect to each other to eliminate the output voltage ripples with low capacitance requirements.The proposed seriesmodular and cascade configurations show the intrinsic merits of being readily applicable to multistage power switching converter. The developed topology has been implemented on a 5-kw prototype converter to test its feasibility.
