| Abstract |
This paper presents the method of current higher harmonics control for grid connected powerelectronic converter by means of a digital comb filter application. The proposed method providesmultiple harmonics compensation and simple implementation. The Proportional-Resonant (PR)control was complemented with appropriately tuned comb filter which resulted in reduced mitigationof output current harmonics and reduced THD. Two types of comb filters have been verified as aharmonic compensator namely feedback and feedforward structures. The compensator based on thefeedback comb filter included additional casual FIR low-pass filter for increased robustness. ProposedFIR filter is casual therefore its implementation on the digital microprocessors is greatly facilitated.The experimental results have demonstrated the effectiveness of proposed solution for grid connectedconverter operating in a network with distorted supply voltage. |
