Electrolysis of water to produce hydrogen is a technology that uses direct current (DC) to decompose water into hydrogen and oxygen gases. The core equipment includes electrolyzers and rectifying power supplies, with the latter converting alternating current (AC) from the power grid or new energy sources into stable DC power. Under the action of DC electricity, the electrodes in the electrolyzer release oxygen at the anode and hydrogen at the cathode. This process is suitable for green hydrogen production and can achieve zero carbon emissions when combined with renewable energy sources. The power supply for electrolysis of water converts AC power into high-voltage DC power to drive the reaction, precisely meeting the voltage and current density requirements of the electrolyzer. It serves as the "energy hub" for green hydrogen production, and its technological upgrades determine the efficiency and economy of hydrogen production. The future development is oriented towards high efficiency, high adaptability, and high intelligence to support the large-scale production of hydrogen from renewable energy sources, contributing to global carbon neutrality.

The product strictly adheres to international and industry standards such as IEC 62477-1 (Safety Requirements for Power Electronic Converters) and GB/T 36282 (Technical Specifications for Electrolytic Hydrogen Production Systems), integrating features like backflow prevention, dual magnetic isolation design, and modular redundancy backup functions. It is compatible with PV/wind grid-connected interfaces and intelligent electrolyzer systems, supporting both off-grid and grid-connected hybrid hydrogen production modes. The product range includes silicon-controlled rectifier (SCR) series power supplies and silicon carbide (SiC) series power supplies, with power ratings from 76kW to custom megawatt-level requirements. It is widely applied in green hydrogen integration projects, chemical synthesis, hydrogen energy transportation, semiconductor manufacturing, and other fields, achieving efficient, safe, and low-carbon hydrogen production.
