Introduction to High-Power Electrolytic Power Supplies (for the Electrochemical Industry) High-power electrolytic power supplies are large-scale rectifier systems designed for the electrochemical industry. They are suitable for the electrolysis of non-ferrous metals such as copper, aluminum, magnesium, and zinc, as well as for large-scale chemical processes like the electrolysis of brine to produce caustic soda and chlorine. The output current can reach tens of thousands of amperes, and the equipment typically adopts a cabinet-type or open-frame structure. Applications include non-ferrous metal electrolytic refining (copper, zinc, lead), electrolytic production of caustic soda and potash, smelting of precious metals such as gold and silver, rare-earth smelting (e.g., NdFeB), carbon plants, and diamond smelting.

Introduction to Power Supplies Dedicated to Electrolytic Hydrogen Production: Electrolytic hydrogen production power supplies are rectifier devices that connect the power grid to the electrolyzer, converting alternating current into stable direct current to drive water electrolysis for hydrogen generation. Depending on the electrolyzer type (alkaline ALK/PEM) and the technological route, hydrogen production power supplies are classified into two categories: thyristor-based and IGBT-based. Application of alkaline electrolysis (ALK) and PEM electrolysis for green hydrogen production in wind–solar‑hybrid projects: industrial decarbonization and green hydrogen metallurgy. Product features: IGBT-based hydrogen generation power supply with an output response time of less than 100 ms, enabling immediate response to rapid fluctuations in photovoltaic and wind power generation.

Characterized by robustness and durability, as well as relatively low cost, it is a mature solution in the fields of hydrometallurgy and hydrogen production. Applications include high-power electrolytic metallurgy (aluminum, magnesium, zinc, etc.), hydrogen production via water electrolysis (alkaline electrolyzers), caustic soda and chlorine production through brine electrolysis, as well as electric heating for carbon plants and refractory materials. Key product features: output current up to 0–50,000 A, wide power range per unit, and DC output.

Introduction to High-Frequency Switching Electrolytic Power Supplies (IGBT/PWM Type): These power supplies utilize IGBT power devices and PWM modulation technology to convert AC power into low-voltage, high-current DC power, making them suitable for electrochemical processes such as electrolysis, electroplating, and anodizing. Compared with traditional thyristor-based rectifier power supplies, it offers significant advantages such as a compact footprint, high efficiency, low ripple, and high control accuracy. Applications of non-ferrous metal electrolysis: hydrogen production via copper, aluminum, zinc, magnesium, lead, manganese, and other metals; electrolytic saltwater treatment; electroplating and electropolishing; wastewater electrolysis and electrochemical treatment. Product features: compact size and weight, with adjustable dimensions.

Product Overview: The electrolytic rectifier power supply is a high-power DC power supply specifically designed for electrochemical processes. Its primary function is to convert three-phase AC power into low-voltage, high-current, highly stable, and adjustable DC power, providing continuous and reliable DC power to the electrolytic cell. Its operating principle is as follows: Three-phase AC power is isolated and stepped down by a rectifier transformer, then rectified into an adjustable DC output using thyristors or high-frequency switching devices. Current equalization is achieved through in-phase inverse-parallel or modular parallel connection techniques. Electrolytic rectifier power supplies are widely used in non-ferrous metal electrolysis (copper, aluminum, zinc, lead, manganese, etc.), chlor-alkali chemical industry, water electrolysis for hydrogen production, chlorine generation via electrolysis, and gold…
