Rectifiers

Power conversion for green hydrogen power supply.

As a world-leading converter manufacturer and a trusted partner to top electrolyzer OEMs, we design and manufacture rectifiers to accelerate green hydrogen production and the renewable energy transition.

Full-scope rectifier partner

Customised rectifiers built on proven wind energy experience and technology.

With over 40 years of experience delivering power converters to the wind industry, we bring proven expertise to rectifiers for green hydrogen production, offering solutions that are both customised and cost-efficient.

We provide three types of rectifiers utilising both Active Front End (IGBT) and Diode technologies, specifically designed to align with your electrolyzer’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.

Rectifiers designed with high efficiency

Developed specifically for green hydrogen application, our rectifiers are customised to your electrolyzer’s operational range, and plant-specific output.

High DC Voltage Rectifier (AFE)

Developed using Active Front End (IGBT) technology, this rectifier provides a scalable DC voltage range of 1070–1500VDC.

 

Medium DC Voltage Rectifier (AFE)

Developed using Active Front End (IGBT) technology, this rectifier provides a wide DC voltage range of 50–1200VDC.

 

Medium DC Voltage Rectifier (Diode)

Developed using traditional Diode technology, this rectifier provides a flexible DC voltage range of 50–850VDC.

 

Select the right rectifier technology

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.

At KK Wind Solutions, we employ two rectifier technologies: traditional diode and Active Front End (IGBT), which can be further customised to your plant-specific requirements.

Selecting the right rectifier technology for a green hydrogen plant’s Power Supply Unit is essential, as it influences both efficiency and production output.

Factoring in power quality and grid compliance from the outset enables calculating the plant’s economic performance and total cost of ownership, effectively balancing capital and operating costs.
