High DC Voltage Rectifier (AFE)
Compact rectifier for high DC voltage
Combining high efficiency, scalable DC output, and a compact design, our High DC Voltage Rectifier (AFE) delivers reliable and cost-effective performance.
Developed using Active Front End (IGBT) technology, the High DC Voltage Rectifier (AFE) provides a nominal 12MW output, scalable in 3MW steps.
With a scalable DC current range of 2200–8800ADC and a DC voltage range of 1070–1500VDC, it delivers high efficiency and key grid compliance features, including precise power control, low harmonics, and active Fault Ride-Through (FRT).
Optional configurations offer a wider DC voltage range of 936–1500VDC or up to 13MW output.
Key benefits
Designed for high DC voltage green hydrogen applications.
Scalable DC output to match the operational range of the electrolyzer.
Ideal for large-scale plants and megawatt upscaling.
Compact footprint for challenging layout requirements.
AFE technology provides high power quality and low harmonic distortion.
Seamless plant integration to ensure TSO/grid compliance.
Rectifier technology comparison
At KK Wind Solutions, we employ two rectifier technologies: Active Front End (IGBT) and traditional diode.
Diode/Thyristor Rectifiers
Efficient and reliable, these rectifiers are ideal for small-scale projects where basic control and standard power quality are sufficient. Due to unidirectional power flow and lack of active power factor control, they require additional filtering, which increases operating costs.
Active Front End (IGBT) Rectifiers
Widely used in renewable energy systems, AFE rectifiers offer fast, precise control, reactive power capability, and superior DC voltage regulation. Their high efficiency, reduced harmonic distortion, and scalability make them ideal for large green hydrogen plants and evolving grid requirements.
