Hydrogen

Dynex has a rich history in producing multimegawatt power conversion solutions. Our power converter technology is a perfect fit for power supplies needed for hydrogen electrolysis applications.

Power Converters

Dynex is uniquely able to design power converters with its own tailored semiconductors, as well as benefiting from expert knowledge of wear out mechanisms and capability outside of the common operation.

Dynex power converter technology is ideally suited for the power supplies needed for hydrogen electrolysis, whether that may be from a renewable source such as solar, wind and wave power, or simply grid connected. Using the latest IGBT AFE (Active Front End) technology our supplies are optimised in terms of efficiency, size, power factor correction and harmonic distortion.

With a wealth of experience in designing power converters our team of application engineers are able to match and refine a power supply to meet the customers needs, whether that be DC ripple requirements, space limitations or differing incoming supply voltages.

All of our power supplies feature a Dynex designed controller that makes it easy to interface the electrolyser control system with our power supply. This gives constant status feedback to ensure the smooth and efficient running.

With the production of hydrogen, safety is paramount, this is why our power supplies feature an MCCB on the input side that has a trip that can be customer controlled to instantly cut power in the case of an emergency shutdown.
