A Hydrogen Electrolysis Rectifier Power Supply is a specialized electrical device used to convert alternating current (AC) from the power grid into direct current (DC) for hydrogen production through electrolysis. In this process, the rectifier provides the stable and controlled DC voltage needed to split water into hydrogen and oxygen gases. This power supply is essential for efficient and reliable hydrogen production in various applications, including industrial hydrogen generation, fuel cell technology, and renewable energy storage. It features high efficiency, precise voltage regulation, and safety features to manage the electrolysis process effectively and support the growing demand for clean hydrogen energy solutions.
Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called electrolyze. Electrolyzes can range in size from small, appliance-size equipment that is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be tied directly to renewable or other non-greenhouse-gas-emitting forms of electricity production.
The DC power supply required for electrolyzing water to produce hydrogen generally has higher voltage and lower current. This means that in the rectifier transformer, the voltage will be greatly increased and the current will be reduced accordingly.
Therefore, the design of the rectifier transformer must take into account the voltage and current requirements to ensure that the process of electrolyzing water to produce hydrogen is as efficient as possible. In addition to voltage and current requirements, the stability of the rectifier transformer is also one of the key factors. This is because once the output of the rectifier transformer is unstable, it will affect the process of electrolyzing water to produce hydrogen and may cause equipment damage or other problems. Therefore, stability is a factor that must be considered when designing a rectifier transformer.
The global key manufacturers of Hydrogen Electrolysis Rectifier Power Supply include ABB, Hubei Green Power, Siemens, Jiangxi Liyuan Haina, Sensata Technologies, Sungrow Power Supply, Prodrive Technologies, AEG Power Solutions, Comeca and American Superconductor, etc. In 2024, the global top five players had a share 58.14 % in terms of revenue.
The integration of wind, solar, and hydrogen production is accelerating, leading to an increase in the scale of single-cell hydrogen production and driving the expansion of rectifier power supplies for hydrogen generation. Green hydrogen projects are experiencing rapid growth, with individual project capacities continually rising. On one hand, as the hydrogen output capacity of electrolyzers improves, the power requirements for rectifier systems are expected to increase accordingly. On the other hand, with the growing scale of wind and solar power generation and the expanded use of surplus renewable electricity for hydrogen production, the market share of PEM water electrolysis technology continues to rise. Against this backdrop, the market share of IGBT-based rectifier power supplies for hydrogen production is also expected to increase.
From the current market and technological development perspective, hydrogen production rectifier power supplies serve as a vital "bridge" connecting the hydrogen production system to the power grid. At present, the two mainstream technologies in this field are SCR and IGBT. While SCR-based rectifiers are more widely used under current conditions, IGBT-based rectifiers offer stronger grid protection and better adaptability to power fluctuations. With the emergence of large-scale (megawatt-level) electrolyzers and hydrogen production scenarios involving weak or off-grid power systems, IGBT technology is expected to see broader application. Similar to the role of photovoltaic inverters in the solar power industry, hydrogen production rectifier power supplies are poised to follow a growth trajectory in tandem with the expanding hydrogen market.
