Bidirectional DC Power Supply

Benefits and Enhancements

  • Active voltage regulation is possible. The DC voltage level can be higher than a rectified AC voltage and is independent from the AC level.
  • Enables full separation from the AC grid. In case of a net fault the DC grid can operate with stored energy.
  • Reduced harmonic distortion on AC side. No additional power factor correction unit is required.
  • Reduced risk of production faults.
  • Peak power reduction is enabled in combination with an energy storage system.
  • Possibility of energy feed-back into the AC grid.
  • Redundant parallel connected power supply units are possible. Shutdown of single power supply units at low load factors is a feature to save energy.
  • The active AC/DC power supply may be combined with photovoltaic cells and battery storage in the same DC grid.
