Abstract
This research paper proposes a novel high step-up dc-dc converter comprising a cascaded assembly of a coupled inductor as well as voltage doubler circuits. A high step-up voltage gain with an appropriate duty ratio as well as low voltage stress on the power switches is achieved by this converter. The output consists of the recycled energy which is stored in the leakage inductor of the coupled inductor. A discussion containing the details of the operating principles as well as steady state analysis of the proposed converter is also included. The performance of the proposed converter is verified in the laboratory by implementing a prototype circuit of the converter that is being proposed finally.
