Containerized AC/DC IGBT Hydrogen Power Supply
Before leaving our factory, each hydrogen production rectifier undergoes full system functional tests, insulation hi-pot verification, protection logic validation, and long-term stability runs — proven to withstand years of continuous operation in harsh grid and renewable environments.
The DC power supply series includes three main product lines:
AC/DC IGBT Hydrogen Power Supply: Two‑stage (AC/DC+DC/DC) for grid‑connected and wind‑solar hybrid systems.
DC/DC IGBT Hydrogen Power Supply:Single‑stage DC/DC for PV‑direct and DC‑coupled off‑grid hydrogen production.
Containerized AC/DC IGBT Hydrogen Power Supply: Integrated MV transformer + rectifier + cooling in a 40ft GP container, ready for direct MV grid connection.
All DC power supply products are compatible with both PEM (proton exchange membrane) and alkaline (ALK) electrolyzers. The output voltage is continuously adjustable from 0 to 700V DC, covering the full operating range of both technologies. This dual compatibility gives you maximum flexibility when selecting or upgrading electrolyzers.
IGBT full‑control topology: Enables <100ms dynamic response and THDi ≤3% without external filters.
100% liquid cooling:Provides 20‑30× better heat dissipation than air cooling, enabling compact design, IP54 protection, and longer lifetime.
Wide load range (10–120%): Handles electrolyzer start‑up, partial load, and peak demand without derating.
Modular parallel design: Scale from 1.5MW to hundreds of MW by paralleling units.
High efficiency: AC/DC models ≥98%, DC/DC models ≥99%.
Grid adaptability: Supports low short‑circuit ratio, weak grids, and wide voltage/frequency variations (±10%).
Load response time is ≤100ms from 0% to 100% load step. This millisecond‑level response is essential for wind‑solar‑hydrogen systems where renewable power fluctuates rapidly. It protects the electrolyzer from voltage/current spikes and ensures stable hydrogen production even under weak grid or off‑grid conditions.
THDi (Total Harmonic Distortion) is ≤3% at above 30% load. Low harmonics mean the power supply does not pollute the grid, eliminating the need for expensive external filtering equipment. It complies with IEEE 519 and global grid codes, making grid connection simpler, cheaper, and faster.
