In this thesis, a novel high step-up boost converter with coupled inductor is proposed. The circuit topology of the proposed converter is derivatived from the conventional boost converter with coupled inductor connection such that high step-up voltage gain with proper duty ratio is achieved. Besides, the converter has the advantages of simple circuit topology and high efficiency which can be applied to renewable energy systems. The operating principle, steady-state analysis, and efficiency analysis are presented. Finally, an experimental prototype with 24 V input and 200 V/ 2.5 A output is implemented to verify the theoretical analysis.
