This paper discusses the design of a repetitive feedback
controller for a grid-connected two-level three-phase voltagesource inverter connected between a DC source and the grid through an LCL filter. The controller incorporates a classical
two loop feedback of the output current and the capacitor
current in addition to a repetitive feedback loop. The results
show that the proposed technique improves the steady state
error and the total harmonic distortion of output current in
presence of utility harmonics.
