Rectifiers designed for electrolyzer power supplies, optimised for plant-specific output and efficient hydrogen production.
For more than 45 years, we have delivered power converters to the wind industry. As a world-leading converter manufacturer and trusted partner to leading electrolyser OEMs, we now apply that expertise to rectifiers for hydrogen production with customised, cost-efficient solutions.
We provide two types of rectifiers utilising Active Front End (IGBT) technology , specifically designed to align with your electrolyser’s operational range and plant-specific output.
Leveraging a flexible global value chain and extensive manufacturing know-how, we accelerate the development of high-quality rectifiers with enhanced reliability and grid compliance.
Our rectifiers are developed and customised to your electrolyser’s operational range and plant-specific output.
Our high DC voltage rectifier is designed with Active Front End (IGBT) technology. With its compact footprint, this rectifier provides a scalable DC voltage range of 1070-1500VDC.
Our medium DC voltage rectifier, designed with Active Front End (IGBT) technology, and an integrated DC step-down module, delivers a DC voltage range of 50-1200 VDC.
With an established track record within the renewables sector, we stand as the largest converter manufacturer in the wind industry.
Our proven expertise lies in supporting our customers in scaling technologies from prototypes to global manufacturing on a gigawatt-scale, all backed by our impressive annual production capacity exceeding 20 GW.
Moreover, we are a trusted supplier of electrolyzer Power Supply Units to the world's leading electrolyzer OEMs in the hydrogen industry.

At the core of the Power Supply Unit (PSU), the rectifier converts AC into DC current, driving efficiency and reliability for both the PSU and the electrolyzer.
Choosing the right technology is essential, as it directly impacts efficiency, production output, power quality, and grid compliance.
Factoring in power quality and grid compliance early enables accurate calculation of plant economics and total cost of ownership.
