This paper proposes a dual input single output DISO step up dc dc converter exhibiting high voltage gain for grid connected applications The main advantage of the proposed concept is the common ground between input and output ports with a continuous input current profile at both input ports The operating principle and steady state analysis are presented in detail The voltage gain expressions for both inputs are obtained using equivalent circuit analysis The voltage and current stresses of all components and the design equations for L C elements are derived Preliminary simulation results are presented using the LTspice simulator to demonstrate the key operational characteristics of the proposed DISO step up converter Finally the converter operation and analytical studies are verified through sample experimental results captured using a prototype converter
