Step-Up Converter with High Order Selectivity

A new DC-DC boost converter with a positive output voltage that can be applied in applications requiring a wide range of voltage gain is proposed. Using a novel switch network, the proposed converter can achieve a high order of boost gain under low current stress while maintaining high efficiency. The operation of the proposed topology is analyzed, and a comparison with other topologies is done. A prototype circuit has been made for verification of the proposed topology, and its experimental results are analyzed. The experimental results show that the proposed converter can achieve quadratic, cubic, and more orders of gain with proper duty ratio.
