摘要

Multi-input–multi-output (MIMO) DC–DC converters have become integral to modern power electronic systems, offering significant advantages over traditional single-input–single-output converters. These advantages include reduced component count, enhanced efficiency, flexibility, reliability, compact size, improved power quality, scalability, and seamless integration with energy storage systems. These features make MIMO converters indispensable for various applications. However, they also present challenges such as increased component complexity, cross-regulation issues, and sophisticated control requirements. To address these challenges, a novel converter topology is proposed in this paper. The proposed method features a reduced component count and independent duty ratio control, effectively eliminating cross-regulation issues. This design is tailored for remote village DC microgrid applications. The performance and effectiveness of the proposed converter are validated through simulation and experimental results using a 250 W prototype.
