Abstract

The production of hydrogen from electrolytic water using renewable energy is a highly effective way to reduce carbon emissions and has garnered significant attention from scholars around the world. As the crucial link between the electrolyzer and the DC bus, the performance of the DC-DC buck converter is paramount. Therefore, a multiphase stacked interleaved buck converter (MSIBC) is proposed in this paper, which offers superior performance in terms of low voltage, high current, and minimal current ripple. This paper delves into the circuit design methods and current ripple elimination mechanisms of this topology. Furthermore, a detailed analysis is conducted to compare the performance of MSIBC with that of interleaved buck converter (IBC) and stacked interleaved buck converter (SIBC), covering factors such as efficiency, inductor current stress, and switching current stress. The results indicate that MSIBC offers superior efficiency, low inductor current stress, and switching current stress. Additionally, MSIBC enables redundant control of the system. Finally, experimental and MATLAB/SIMULINK simulation results confirm the accuracy of ripple cancellation.

具有极低输出电流纹波和低电流-电压应力的高效多相叠加交错直流-直流降压转换器
利用可再生能源从电解水中制氢是一种减少碳排放的高效方法,已引起世界各地学者的极大关注。作为电解槽与直流母线之间的关键环节,直流-直流降压转换器的性能至关重要。因此,本文提出了一种多相叠加交错降压转换器(MSIBC),该转换器在低电压、大电流和最小电流纹波方面性能优越。本文深入探讨了这种拓扑结构的电路设计方法和电流纹波消除机制。此外,本文还进行了详细分析,比较了 MSIBC 与交错降压转换器(IBC)和堆叠交错降压转换器(SIBC)的性能,包括效率、电感器电流应力和开关电流应力等因素。结果表明,MSIBC 具有更高的效率、更低的电感器电流应力和开关电流应力。此外,MSIBC 还能实现系统的冗余控制。最后,实验和 MATLAB/SIMULINK 仿真结果证实了纹波消除的准确性。
