ADOR heavy-duty rectifiers power electrolytic cells that produce hydrogen from electrolysis. Electrolysis is the process of using electricity to split water into hydrogen and oxygen molecules. ADOR supplies electrolyser manufacturers and hydrogen producers with DC Power sources and rectifiers to power these hydrogen generating cells.

The system is designed to meet the most demanding specification of electrolytic water hydrogen production industry. These are available in 6, 12 and 24 pulse systems and thyristor rectifiers are engineered, designed, manufactured and tested to internationally recognized standards including CE certification. Our design capabilities include automatic power factor and harmonic mitigation. We also offer a state-of-the-art switch mode technology with systems designed to be scalable, simple to use and easy to maintain.  Only a basic maintenance check procedure is needed to ensure your rectifiers continue running, saving both time and maintenance repair costs. All high power thyristor rectifiers are bespoke custom designed for our customer’s requirements, ensuring you get the exact rectifier your process requires with the most advanced Digital Regulations and electronics.

Rectifier technologies and topologies in support of hydrogen generation includes:

6, 12, 24, and higher pulse rectification with SCR (thyristor) only control as well as DC bus front ends for high-frequency designs

High-frequency IGBT based designs for power control in place of SCRs (thyristors) Special ripple filtering utilizing inductive and / or capacitive filtering to meet electrolytic cell ripple requirements Digital control technology with high-speed networking and holistic alarm and fault monitoring
