Hydrogen Production

Hydrogen energy, the world's cleanest energy source, is poised to play a pivotal role in decarbonizing multiple industrial sectors. The advancement of electrolyzer power supplies is essential to this rapid evolution, since these systems must deliver stable low-DC-voltage output at megawatt-scale power levels – a critical technical challenge in green hydrogen production.

As an impeller in power electronics, VEICHI, starts to provide the upstream hydrogen industry with its VHP power supply solution featuring high safety, high-efficiency, and low-harmonics based on current mainstream alkaline electrolyzer and PEM electrolyzer power supply needs. This solution consists of the VHP series DC power supply system and the VHP series DC power supply cabinets so to adapt to the renewable energy fluctuations better on the adaptor side, providing high-quality power output for hydrogen production from the electrolyzer with high efficiency for uninterrupted 24h operation. With a deep understanding of user needs for product, service, and solution customization, our system features leading low-energy-consumption designs that deliver impressive cost efficiency in hydrogen production. Various current density settings enable customized output and energy efficiency, while fully automated remote control offers a comprehensive upgrade in system intelligence.
