New Repetitive Current Controller for PWM Rectifier
Abstract This paper analyzed and designed a new Repetitive Current Controller (New RCC), performing a comparison with a traditional RCC. Based on the tracking performance by the original PI controller, the New RCC uses another PI controller to replace the compensator to achieve better control performance.
