Abstract: Proportional-resonant (PR) controllers for current control are described in this paper. They are suitable for converters connected in a grid. In single phase converters, steady state error problems with PI controller are reduced with this controller. Also, with PR controllers, the selective compensation of harmonics is possible. The critical power quality issue that is degrading the performance on load side and source side is the voltage and current ripples. This causes reliability concerns. These can be overcome by using PR controller. In this paper, designing of PR current controller as a selective harmonic compensator has been presented.
Keywords: Harmonic Compensation, Proportional Resonant Controller.
