Design and simulation of modified multi-input interleaved boost converter for renewable resources

In the present scenario due to the advancement of technology energy consumption per capita has increased a lot. But the natural resources like fossil fuel are depleting day by day. To enhance the use of renewable energy in the present situation the development of converter circuit is most essential. This paper proposed a newly modified multi-input interleaved DC-DC boost converter. This proposed topology interfaces three unidirectional input power sources in a combined structure. This converter is attractive for alternative energy sources such as photovoltaic sources (PV), fuel cells, and batteries. This paper aims to design a high-performance multi-input boost converter. The proposed topology uses five switches that are separately controlled with five different duty ratios. Computed duty ratios are applied at different modes of operation and hence the switch realization of the new converter is obtained. The proposed topology has been realized through simulation using the MATLAB Simulink. The outputs of the simulated circuit confirm the feasibility of real-time implementation.
