Power boxes for hydrogen electrolysis

We have been building rectifiers for decades! From a few KW up to over 30MW. The Power-Boxes contain everything - from medium voltage supply to DC supply of the stacks. Whether thyristor rectifier or IGBT rectifier, both technologies have their advantages and disadvantage. Nevertheless, thyristor has under all circumstances the better efficiency, therefore at IPS-FEST we use thyristor only.

In terms of transformer design and circuit topology, our power-box is precisely tailored to the requirements of your electrolysis. As a result optimal efficiency and high reliability reduce operating costs.
