I. Core Technological Advantages of Hydrogen Production Power Supplies

1>High-Frequency Switching Technology: An Efficiency Revolution

Hydrogen production power supplies utilize IGBTs or third-generation semiconductor SiC power devices, with operating frequencies reaching 20-50kHz, representing a qualitative leap compared to traditional solutions. High-frequency operation brings three major breakthroughs:

• Conversion efficiency up to 99%: The silicon carbide (SiC) solution further improves efficiency by 1-2 percentage points compared to traditional IGBTs, significantly reducing energy costs.
• Fast Dynamic Response: Power regulation response time ≤0.1 seconds, enabling real-time tracking of renewable energy fluctuations and achieving "flexible hydrogen production."
• Low Ripple Output: Extremely low output voltage ripple, effectively protecting the electrolyzer and extending equipment lifespan.

2>Modular Design: Smarter Operation and Maintenance

• Hot-swappable Maintenance: Each power module operates independently; faulty modules can be replaced online, minimizing downtime.
• Flexible Expansion: Power modules can be flexibly added or removed according to hydrogen production needs, achieving "on-demand configuration."
• Remote Intelligent Operation and Maintenance: Built-in big data recording function, real-time monitoring of current, voltage, and temperature curves, supporting remote diagnostics via cloud platform.

3>. Superior Power Quality: Grid-Friendly Design

• Compared to traditional thyristor solutions, IGBT hydrogen production power supplies offer significant advantages:
• Harmonic Content <3%: No need for additional filtering devices, reducing supporting costs
• Power Factor >99%: Reduces reactive power losses and provides reactive power support capability
• Low Switching Losses: Soft-switching technology reduces electromagnetic interference and improves system reliability

II. Economic and Environmental Adaptability Advantages

1,Overall Cost Advantage

• Although the initial purchase cost of IGBT hydrogen production power supplies is higher, the total life-cycle cost is more competitive:
• Electricity Cost Savings: Efficiency improvement of 1-2 percentage points can save millions of yuan in electricity costs annually in a hydrogen production base with tens of thousands of tons of production capacity.
• Reduced Heat Dissipation Costs: High efficiency means low heat generation, reducing investment in cooling systems.
• Reduced Space Costs: High power density design significantly reduces volume and weight, saving installation space.

2,Wide Adaptability Design

• Operating Environment: -25℃ to +45℃: Meets the hydrogen production needs of harsh environments such as high altitudes and deserts.
• Compatible with Multiple Electrolyzers: Perfectly matches both alkaline and PEM electrolyzers.

III. Application Scenarios Advantages: The Best Partner for Renewable Energy

• In fluctuating power supply scenarios such as photovoltaic and wind power, hydrogen production power supplies demonstrate unique value:
• Sub-second Response Speed: Quickly smooths fluctuations in renewable energy generation, maintaining efficient and stable operation of the electrolyzer.
• Supports Off-Grid/Weak Grid Connection: Provides technical support for distributed hydrogen production in remote areas.
• Improves the Economics of Green Hydrogen: The North Sea wind power hydrogen production base in Germany uses a 10000A hydrogen production power supply, achieving an annual production capacity of tens of thousands of tons.
• Wide Applications in Industrial Fields
• From chemical and metallurgical industries to semiconductor manufacturing, hydrogen production power supplies are becoming key equipment for industrial decarbonization. China Baowu Steel's hydrogen-based ironmaking project and various fuel cell hydrogen refueling stations have adopted this advanced technology.
