DSP Based Hardware Implementation of Repetitive Current Controller for Interleaved Grid Connected Inverter

摘要

The performance of the repetitive controller (RC) for classical inverters (e.g. two-level LCL filter based inverter) can decline if the system bandwidth is not sufficient enough due to much larger LCL filter component values. The novel interleaved inverters can provide higher bandwidth than the classical inverters because of low filter values. This paper reflects upon the analysis and hardware implementation of the RC for interleaved inverter using DSP. High quality (very low THD) output current is demonstrated through simulation and experimental results.%W artykule przedstawiono analiz? i implementacj? na DSP sterowania powtarzalnego dla badanego falownika typu interieaved.
