Clean Power for Green Hydrogen
Yiwei's green hydrogen power supply solutions provide high-efficiency rectification and power conversion systems for alkaline and PEM electrolyzers. By pairing renewable energy sources — solar, wind, or hybrid — with specialized hydrogen power supply equipment, we enable cost-effective, low-carbon hydrogen production at scale.
Our hydrogen power supply system converts AC grid or renewable power to stable, controllable DC output for electrolyzers. With high-efficiency IGBT rectifiers achieving 98%+ efficiency and low total harmonic distortion, the system ensures optimal electrolyzer performance and long service life.
From MW-scale hydrogen production plants to integrated renewable-hydrogen energy bases, Yiwei delivers complete power supply solutions including rectifiers, transformers, switchgear, EMS, and system integration — compliant with international standards for hydrogen production safety and grid connection.
Efficient. Stable. Scalable.
A green hydrogen power supply system that maximizes electrolyzer efficiency and enables large-scale renewable hydrogen production.
Renewable Hydrogen Power
Directly couple solar, wind, or hybrid renewable generation with electrolyzers through our power supply system, producing truly green hydrogen with zero grid emissions.
High-Efficiency Rectification
IGBT-based rectifiers achieve 98%+ conversion efficiency with low THD, minimizing energy loss and ensuring stable DC output for optimal electrolyzer performance.
Stable DC Output
Precise voltage and current control across a wide 200–1500V DC range ensures electrolyzers operate within optimal parameters, improving hydrogen yield and cell life.
System Integration
Complete turnkey solutions including rectifiers, transformers, switchgear, EMS, and protection systems — single-point responsibility for the entire power supply chain.
Engineered for Electrolyzer Loads
Every hydrogen power supply system is designed around the specific electrolyzer type — alkaline or PEM — and its dynamic load characteristics. The architecture supports both grid-connected and renewable-direct operation modes.
- IGBT rectifier, 200–1500V DC, 98%+ efficiency
- Modular design, 500 kW – 20 MW+ scalable
- EMS with renewable dispatch & load following
- Comprehensive protection: overvoltage, overcurrent, isolation
Built for Hydrogen Production
From industrial hydrogen plants to renewable energy bases, our power supply solutions support every green hydrogen application.
Hydrogen Production Plants
