High-Efficiency Multiphase Stacked Interleaved DC-DC Buck Converter with Very Low Output Current Ripple and Low Current–Voltage Stress
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.
