Abstract:

With the advancement of the national goal of “double carbon”, the hydrogen production by electrolytic water will usher in explosive growth, among which the topology and control of power supply is of great significance to improve the efficiency of hydrogen production system. This paper took the topology of isolated DC/DC hydrogen production power supply as the main line to sort out and analyze, and summarized and analyzed the structures, advantages and disadvantages of single-stage, two-stage, parallel and multi-port DC/DC isolated hydrogen production power supply according to different application scenarios. The analysis shows that the full-bridge resonant converter and the control scheme considering the temperature, pressure and hydrogen/oxygen cross-osmosis feedback of the electrolytic cell will become the development trend of high-power large-scale hydrogen production power supply which can adapt to wide range and strong fluctuation. Moreover, the isolated three-port DC/DC conversion power supply will become the distributed integrated electric-hydrogen coupling development mode in the future. The research of this paper aims to provide theoretical reference for the further research of hydrogen production by electrolytic water.
