Abstract
This paper proposes an Improved Gain Single Inductor Dual Switch Converter (IGSIDSC) for the grid integration of solar and fuel cells, which achieves high voltage gain at reduced duty ratio and with less component count. The proposed converter is designed to operate with a duty ratio less than 50% to ensures reduced losses and less component stress This salient feature makes the proposed converter unique among the other converters reported so far. By reducing voltage stress on switches and diodes, the design permits the use of lower-rated components and reduces the cost. The common ground configuration helps to reduce dv/dt issue. The IGSIDSC is analyzed in steady state with consideration of parasitic resistance for all components of the converter. Further, the simulation results are validated through experimental investigation using the prototype developed in laboratory for the power rating of 200 W. Also, the investigations on steady-state performance and dynamic behavior of the experimental prototype effectively demonstrate the successful operation of the IGSIDSC.
