DC-3 Industrial High-Power DC Power Supply for Green Hydrogen Production

  • 1,25 MW Rectifier Module
  • 2,5 MW Power Frame
  • 10 MW Power Block
1/3

DC-3 from AEG Power Solutions fulfills the most stringent power supply requirements for demanding industrial processes: a perfect stability of output voltage for the best current quality and high efficiency performance. In line with the specificities of those processes, power consumption is as close as possible to a sine wave form. DC-3 is based on proven B12 Thyristor Rectifier and IGBT chopper technology which results in a high power factor of up to 1.

Due to the wide output voltage range, load voltages from 50 V up to 1000 V can be achieved with DC-3. The maximum output current of each DC-3 module is 2000 A. Thanks to its modularity and to the capability of interconnecting up to 8 units into one power block, higher power requirements can be easily met.

The robust and compact design of the DC-3 enables utilization even in harsh environments. DC-3 supplies demanding industrial processes and meets the grid connection requirements without installing additional power factor correction or harmonic filters. This allows to increase the efficiency and decrease the life cycle costs to combine the highest level of reliability with the best economic results.
