Hydra rectifier

6MW SiC-based rectifier, scalable up to 24MW

Hydra is the next generation of rectifiers for electrolyzers based on SiC MOSFET topology. Compared to traditional IGBT or thyristor rectifiers, Hydra brings higher efficiency across the entire load, fast response times, smaller footprint due to lower losses and reducing components required for compensation as well as superior grid and stack compatibility.

Hydra brings high euro efficiency of 98.6% (peak efficiency up to 98.7%) due to its SiC MOSFET topology which is capable of operating at higher switching frequencies compared to other rectifiers. The faster switching capabilities enables the design of smaller passive components such as inductors and capacitors, which reduces both system size and weight while maintaining high efficiency. Additionally, lower conduction losses in the system reduces the need for large heatsinks and minimize power wastage as heat improves the overall efficiency.

*Note: EURO efficiency represents the weighted average of the converter efficiency across the power output range. The modular design allows for adjustable rack sizes, which can be cascaded to meet varying power requirements.
