Simulation and Experimental Validation of An Improved High Step-Up Boost Converter Suitable for Smart Micro-Grids

The high-gain boost DC-DC converters are good options for smart-grid and renewable energy system applications. The suggested common-grounded structure has high boosting ability (even at low duty ratios) and continuous input-current primacy that are proofed by mathematics calculations. Minimum switching frequency as well as critical inductances required for sustaining Continuous Conduction Mode (CCM) operation of converters have been computed. Also, the comparative analysis has been done, which certifies the high boosting capability per device of suggested configuration. In addition to open-loop simulation, the dynamic behavior of closed-loop system has also been investigated.
