Dynex has delivered its first IGBT based Hydrogen Electrolyser power supply unit. The power supply will be deployed to generate Hydrogen from a dedicated solar farm. The delivery of the power supply is the output of a year of development in enabling technology and capability by the Power Assemblies Engineering team, who have developed the Power electronics, Control Electronics, Mechanical design and Software. The Power Supply’s manufacture required new techniques and skills to produce a high quality end product.
As a manufacturer of semiconductors and power converters, Dynex is uniquely able to design power assemblies with tailored semiconductors, as well as benefiting from expert knowledge of wear out mechanisms and capability outside of the common operation. 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. The HY-Power range is the perfect fit for all types of electrolysis, with power levels from 150kW up to 2MW. Our HY-Power range of active front end-based rectifiers are optimised in terms of reactive power, harmonics (THDi) and DC current ripple, with output voltages available from 50V to 2000V and current up to 20kA. They are designed for high efficiency, which is typically greater than 95% including the reactive components.
