Scope

Scope: This document specifies the product types, basic functional requirements, performance requirements, and protection requirements for hydrogen rectifier power supplies that provide DC power to electrolyzers in pressure-type hydrogen production systems by electrolysis of water. This document applies to hydrogen rectifier power supplies in alkaline water electrolysis hydrogen production systems and PEM water electrolysis hydrogen production systems, with an AC input voltage not exceeding 1,000 V and a DC output voltage not exceeding 1,500 V. Main technical content: According to the "Medium- and Long-Term Plan for the Development of the Hydrogen Energy Industry (2021-2035)" issued by the National Development and Reform Commission and the National Energy Administration in 2022 (hereinafter referred to as the "Plan"), by 2025, the goal is to "achieve a hydrogen production volume of 100,000-200,000 tons/year from renewable energy, making it an important component of new hydrogen energy consumption and reducing carbon dioxide emissions by 100-200 million tons/year"; by 2030, renewable energy hydrogen production will be widely applied, providing strong support for achieving the carbon peaking target; and by 2035, the proportion of renewable energy hydrogen production in terminal energy consumption will be significantly increased, playing an important role in supporting the green transformation of energy. Given the massive demand for renewable energy hydrogen production and the carbon dioxide reduction target, renewable energy hydrogen production devices are an important carrier for achieving this goal. Among them, efficient, reliable, and safe hydrogen production power supplies are of utmost importance in ensuring the basic principle of "safety first and clean and low-carbon" in hydrogen production systems. The hydrogen rectifier power supply (hereinafter referred to as the "power supply") connects to the AC power system at the AC input end and to the electrolyzer at t
