Modified boost with switched inductor different configurational structures for DC-DC converter for renewable application

The proposed work represents the modified high voltage conversion boost converter (MBC) and its four different configurations using Switched Inductor (SI) structure-Modified Boost Converter with LL Configuration (MB-LL), Modified Boost Converter with XL Configuration (MBSI-XL), Modified Boost Converter with LY Configuration (MBSI-LY), and Modified Boost Converter with XY Configuration (MBSI-XY). All four configurations are having a single controlled device and derive from the conventional boost converter by hosting boosting circuit in the conventional boost converter. The comparative analysis of four configurations of MBC is done in the paper. The voltage conversion analysis by considering internal voltage drop and without considering voltage drop across the passive device is carried out. The comparison of four configurations of MBC is done on the basis of the voltage conversion ratio, number of components and efficiency of the converter. Four configurations of MBC are simulated in MatLab Simulink for 250W. The simulation results validate the achievability of the modified boost converter.
