Abstract :
A novel repetitive control scheme which adopts zero-phase compensated odd-harmonic signal generator, is proposed for three-phase CVCF PWM inverters to simplify the implementation of repetitive controller and track sinusoidal reference signals at much faster convergence rate and high tracking accuracy (very low THD). The simulation results verify the effectiveness of the proposed scheme.
