Multistage switched inductor boost converter for renewable energy application

In this paper Multistage Switched Inductor Boost Converter (Multistage SIBC) is uttered for renewable energy applications. The projected converter is derived from an amalgamation of the conventional step-up converter and inductor stack. The number of inductor and duty ratio decides the overall voltage gain of the projected converter. The projected converter consists of only one controlled power semiconductor device. The 50 KHz frequency is adopted to reduce the L, C value and to suppress the output waveform ripples. The analysis and working of projected converter is discussed in detail. Simulation of the projected converter for three stages is done in Matlab/Simulink (version-2016) and the results are verified with theoretical values.
