The nonlinear dynamic second-order voltage controller guarantees: a) asymptotic average DC-link voltage regulation; b) reconstruction of the current reference derivative; c) filtering properties of the DC-link control loop with respect to the perturbations generated by the high-order active filter current harmonics. The modified current controllers provide harmonic distortions rejection, while voltage controller guarantees keeping the DC-link voltage in admissible range. The simulation study proofs theoretical findings.
