A new modified non isolated dc-dc converter is premeditated for DC microgrid utility. The modified dc-dc converter comprises of voltage multiplier cell (VMC) integrated with dual inductors in the input side of dc-dc converter. The solar and bladeless wind turbine based renewable energy sources are effectively utilized with these modified dc-dc converter. The major issue related with renewable energy sources owing to deliver low output voltage. The lower output voltage issue can be improved with the proposed modified dc-dc high gain non isolated converter. The modified converter makes use of dual inductor (input side of the converter) connected in cascade/parallel sequence with VMC to perform charging/discharging operation. The VMC (output side of the converter) provides voltage lift with better static gain, reduced switching voltage stress and improved dynamic response. The new modified dc-dc non isolated converter is arrived using Matlab/ Simulink 2013a and developed the experimental setup for power rating of 100W. from the analysis both the simulation and experimental model effectively performs with the goals to improve the voltage gain and low voltage stress with reduced duty cycle.
