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.

To increase power density and to allow easier installation on site, a new base frame solution for two DC-3 systems is proposed by AEG Power Solutions. The immediate benefit is that integration is easier in larger systems and it significantly decreases the handling and installation costs on site.

The Power Frame option comprises:

  • 2 Modules of DC-3 installed on a single base frame

  • Prewired AC paralleling cabinet, which allows to choose AC connection top or bottom and comprises a synchronization and decoupling choke as well as optional fuse switches or circuit breakers

  • Single base frame allows forklift handling

  • Optional installation of four Power Frames to form a 10 MW Power Block solution


Additional scope of supply

  • Transformer
  • Outdoor solution
  • Busbar
  • AC-LV-Distribution
  • Cooling system

 

Container / Skid Solution

Both, Power Frame and Power Block, are also available as transformer-rectifier unit (TRU) in a 40ft container or skid solution. Optional MV-switch gear, LV distribution or cooling systems are available.
