Abstract

Recent years have witnessed a growing interest in altering the connection configuration of converters to enhance the electrical efficiency of boost converters within DC-DC converter systems. This paper explores three connection methods for the magnetic integrated switched inductor boost converter: staggered parallel connection, single switched inductor cascade, and double switched inductor cascade. The study introduces these topologies and operation modes, emphasizing their enhancements in terms of voltage gain and inductor current ripple compared to traditional boost converters. Additionally, it summarizes existing research on these connection modes, providing insights for further advancements in this field. The necessity for developing and utilizing new energy sources amid the energy crisis is underscored, with DC-DC converters being pivotal in new energy power generation systems. Boost converters, particularly, have garnered attention due to their efficiency and compactness, prompting extensive research globally. Various strategies, including magnetic integration technology, have been explored to improve these converters, aiming to increase voltage gain and reduce inductor current ripple. Comparative analyses of different connection modes reveal significant advancements, especially in voltage gain, highlighting the potential of these approaches in enhancing the performance of new energy systems. Through tightly coupling discrete inductors using magnetic integration, the proposed converter demonstrates improved electrical performance, making it suitable for various high-gain DC-DC converter applications in new energy systems.
