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 disadvantages - we will provide you with the optimal device for your requirements.

The power supply is precisely matched to the requirements of the electrolysis in terms of transformer design, circuit topology and semiconductor selection (thyristor or IGBT). Optimum efficiency and high reliability reduce operating costs.
