고전류제품 Modular IGBT rectifier 690KW/module
본문
- I-Kraft™ for renewable hydrogen production.
- Modular construction enables flexible power system design tailored to electrolyzer energy requirements.
- We design the power system based on production specifics and grid requirements, considering what’s the most economical solution over lifetime operation.
- Smooth DC current flow towards the electrolyzer.
- Dynamic operational conditions of the power supply.
- Keep your production running in case of run-time deviatio.
- I-Kraft is an active front end, IGBT based power supply, providing high quality power output with minimum power losses in all operation modes. It removes the need for additional accessories for meeting grid requirements and electrolyzer power quality specifications.
- 690kW modular construction enables flexible power system design tailored to electrolyzer energy requirements — giving possibility to adapt the rectifier to the actual power requirement. By clustering the power modules, scaling up of operations can be achieved, with a simplified transformer design.
