Compensation system of reactive energy

Presentation

This power factor compensation circuit developed by the GREEN laboratory at the University of Lorraine can ensure an almost unity power factor for each home, even if the reactive energy consumed is highly variable. It contains a harmonic filter including a compensation capacitor to provide reactive power to the network, a  static fully reversible power converter, an absorption coil, and a control module. 

The reversibility allows the converter to collect the surplus reactive power at the absorption coil. The converter switching frequency is low enough to enable a loss reduction, thus increasing its performance.

Competitive advantages

• Reduction of local energy consumption in homes and SMEs / SMIs;
• A simple, solid, highly compact, economical, long-life conditioner;
• Respect of electromagnetic compatibility standards and harmonic interferences on the distribution network.
  

Applications/Markets

• Domestic sphere and home automation;
• Light industry: Production of household appliances;
• Sector of general public electricity consumption.
  

Intellectual property

• Patent application FR1255667;
• Collaboration sought: Licenses available for the industrialization of the device.
