  • grid current control;
  • wind and photovoltaic systems, grid-connected - using voltage source converter as front-end;
  • basic current control techniques and modulation strategies;
  • current harmonic requirements;
  • demands, made on grid-connected PV and WT systems - and preservation of power quality;
